Q457 Motor Modification for Shaft Position Encoder
:* R33 limits modifications to a motor. Sub item A allows
modifications for connecting "the motor to the ROBOT and actuated part".
Can that rule be adjusted to specifically allow motor modifications for the
purpose of mounting a shaft position encoder directly to the motor?
The purpose of this Q&A is to clarify questions related to _FIRST_
STEAMWORKS. If you have rule suggestions or comments, please contact [Team
Support](mailto:firstroboticscompetition@firstinspires.org).

Q453 FIRST Choice items count toward overall BoM costs?
:* Do the items obtained from FIRST Choice count towards our overall
expenditures taken into account for the Bill of Materials? (i.e., does it
subtract from the overall amount we are allotted to spend on the robot?)
As per Section 8.1, "the Kit of Parts (KOP) ... is the collection of
items listed on any Kickoff Kit Checklists, distributed via _FIRST_ Choice,
or paid for completely, except shipping, with a Product Donation Voucher
(PDV)." Therefore items distributed via _FIRST_ Choice are part of the KOP,
which are exempt from the Cost Accounting Worksheet (CAW) per !R10.

Q450 Monkeys Fist knot in rope contents
:* If we tie a monkeys fist knot in our rope, can we use a
marble/golfball in the center of that knot? The rope we are using is Para
cord (if you need to know).
No, this would violate !I04-D

Q452 Can a "youth" over 18 submit the Chairman's Award?
:* I have a "youth" who is over 18. How will I get her into the youth
registration to be able to submit the chairman's award. I cannot find the
directions.

Q443 When does the T=0 check occur relative to the time when the robot is
disabled?
:* Consider a robot which climbs the rope, displaces the touchpad for
>1 second, and holds position until the robot is disabled, at which point
it immediately back-drives and releases the touchpad. Does the T=0 scoring
check occur before, after, or during the instant the robot is disabled?
Will a robot that behaves in this way score the TAKEOFF bonus? In other
words, is it at all possible for a robot to get the TAKEOFF bonus if it
cannot hold position without power?
ROBOTS are not expected to continue displacing the TOUCHPAD plate past
T=0 without power in order to be awarded "Ready for Takeoff," assuming they
have adequately displaced the TOUCHPAD plate continuously for at least 1
second up to and including T=0.

Q421 Can we use a dye on the rope for aesthetic reasons? Dye must
chemically bond to the rope.
:* We would like to know whether it is acceptable to use a
"universal" dye such as RIT. This is a "direct dye" and bonds to the fibers
of the rope, but we do not believe this affects the operating
characteristics of the rope in any meaningful way.
No, Team-applied dye is not permitted in !I04 (although dye applied by
a manufacturer is permitted as of [Team Update
09](https://firstfrc.blob.core.windows.net/frc2017/Manual/TeamUpdates/TeamUpdate09.pdf)).

Q404 PPE standard
:* Hello, we are attending from Europe & we have difficulty in
finding ANSI approved PPE. Is it possible to use CE approved PPE instead of
ANSI? Looking forward to receive your reply. Thanks
Yes, CE EN166 safety glasses are approved per [Team Update
09](https://firstfrc.blob.core.windows.net/frc2017/Manual/TeamUpdates/TeamUpdate09.pdf).

https://frc-qa.firstinspires.org/qa/449
Q449 Lenght of Rope
:* When interpreting I04 does this rule mean that part of your rope
must be in contact with the floor after it is released?
No, there is no requirement in !I04 that the ROPE contact the floor
when released.

Q448 Clearance for Hanging rope
:* If a robot pulls into the climbing area until its bumpers meet
resistance, how far from the edge of the robot (including bumpers) will the
rope hang? I want to verify how far back the climbing mechanism can be
positioned and still make contact with the rope. I don't see this 'hanging'
dimension anywhere in the manuals.
The purpose of this Q&A is to answer questions regarding the rules of
_FIRST_ STEAMWORKS. Any measurements or materials information can be
derived from the Field Drawings available at:
[http://www.firstinspires.org/resource-library/frc/competition-manual-qa-system](http://www.firstinspires.org/resource-library/frc/competition-manual-qa-system)

Q447 Do the Bumpers on all four sides of the robot need to be bolted on?
:* We know that the outside corners have to be covered with at least
6 inches of bumper, but does the bumper need to be bolted/pinned in on all
4 sides, as in there needs to be a supports device holding the bumpers on
every side of the robot?
Yes, per !R26-G BUMPERS "must attach to the FRAME PERIMETER of the
ROBOT with a rigid fastening system". Also pay special attention to !R31 as
updated in Team Update 05, which specifies, "... a minimum of ½ in. (~12.7
mm) at each end of each BUMPER wood segment must be backed by the FRAME
PERMIETER."

Q446 Is Lift Peg Painted
:* Is the spring portion of the lift peg painted or is it the
standard silver/gray color as sourced from McMaster-Carr?
The peg is not painted.

Q445 Gear used in robot construction
:* Hello, We were looking to use a partial gear in the construction
of one of the manipulators of our robot that would be permanently attached.
We would consider painting the gear if this could cause confusion. Thanks,
Kevin
There are no rules that prohibit using a GEAR as a part of your ROBOT.
Distinguishing the GEAR used on your ROBOT from the GEARS used as GAME
PIECES is recommended to avoid any confusion when assessing how many GEARS
your ROBOT is carrying per !G27.

https://frc-qa.firstinspires.org/qa/442
Q442 Davit locking pin reoval
:* Can the locking pin on the Davit fingers be removed to allow for
the rope loop to be installed? If not can your rope loop (obviously shorter
than 250mm) pass through the davit fingers and around both fingers to
create your retaining feature. ?
Yes, the DAVIT retaining pins are intended to be removed in order to
install or remove a ROPE.

Q441 Fastness on the robot frame protrude past those on the drive chasey
:* We have used 80/20 extrusion in each corner of our robot. We have
just discovered that the fasteners used in the extrusion sit 4mm further
out than the thickest bolt head on the chassey ie the wheel axel which
protudes 6.5mm. These fasteners we have used while slightly outside the
chassey frame are inside the permitted volume. Is this an issue?
We cannot rule absolutely on hypothetical ROBOT designs, and the final
decision as to legality of a particular ROBOT lies with the Lead ROBOT
Inspector (LRI) at each event. !R02 does contain a provision for minor
protrusions, but we cannot definitively state whether your 10.5mm bolt
heads qualify as we lack the complete context your LRI will have to make
that call.

https://frc-qa.firstinspires.org/qa/439
Q439 Electrical linear actualtors
:* Per R82 pneumatic linear actuators are allowed; would a COTS
electrically driven linear actuator (not a solenoid or sold as a servo) be
allowed?
A COTS electric linear actuator is not a pneumatic linear actuator and
therefore !R82 would not apply. If the motor or actuator is not permitted
per !R32, it is not allowed.

438
https://frc-qa.firstinspires.org/qa/438
Q438 Previous Year's KOP Parts
:* As our team works on the Bill of Materials for this year, do parts
included in previous year's kit of parts count as exempt from the cost of
the this year's robot? Examples of this question would include the roboRIO,
voltage regulator, and pneumatic control module, which we recieved in last
year's kit of parts from the rookie kit, but not this year's.
Yes, the definition of Kit of Parts (KOP) includes "any Kickoff Kit
Checklists" which includes the Kickoff Kit Checklist for the Rookie Tote
you received last year.

Q437 FRC Age Requirements
:* Are there official age requirements and/or age limits for students
on an FRC team? I see the marketing materials for Grades 9 - 12 and ages 14
- 18, but I was told these were only recommendations, not requirements
and/or rules

https://frc-qa.firstinspires.org/qa/436
Q436 Please clarify the phrase "included in any Kickoff Kit"
:* In Table 8-1 there is the phrase "included in any Kickoff Kit".
Could you please clarify, does this literally mean "any" kickoff kit? For
example kickoff kits going all the way back to 1992 (not sure if there were
kickoff kits in 1992) or only kickoff kits distributed for the 2017 Game
"Any Kickoff Kit" means "any Kickoff Kit" and is not restricted to the
2017 Kickoff Kits. Please note, you may be asked to provide documentation
that an item was in a Kickoff Kit, especially for older items that
Inspectors may not be familiar with.

Q422 Chairman's Essay
:* Can we use portions of our old essays and just update information,
particularly if we like the way it communicates our thoughts? i.e.
metaphors we've used?
Yes, there are no rules against that.

Q440 using a reducer which wasn't in the kit of parts
:* We were wondering if it was ok to use the reducers from the link
below;
www.li-ming.com/english/index.php?option=com_content&view=rticle&id=374&Itemid=357
thanks in advance,
We cannot rule absolutely on hypothetical ROBOT designs, and the final

https://frc-qa.firstinspires.org/qa/432
Q432 R29B & F Aluminium Bracket Size Limits
:* Are there any size limitations, besides those established in R29B,
on the aluminium brackets allowed under R29F? The limit is 1 inch away from
the frame perimeter, but no limitation parallel to the frame perimeter is
established. Figure 8-4 shows a tiny extrusion, while our team has an angle
bracket which extends several inches away from the corner. However, the
rules do not have any limitations on how long the corner brackets can be,
meaning you could have a metal belt in the bumpers
There are no limits to how far the aluminum brackets allowed by !R29
part F may run parallel to the FRAME PERIMETER, so long as the brackets are
being used for the intended purpose specified in !R29 part F.

https://frc-qa.firstinspires.org/qa/431
Q431 Andy Mark am-2971
:* Can we use am-2971 even though the motor is am-0939 which is not
on the current list of allowed motors? The gearmotor am-2971 has the same
specs as an allowed gearbox with an allowed motor.
Motors not listed in !R32 are not permitted. We recommend contacting
the VENDOR if you need additional clarity on which motor(s) is used in a
particular product.

https://frc-qa.firstinspires.org/qa/426
Q426 Pneumatic air tanks
:* Are we allowed to air up a couple of identical 125 psi air tanks
and change out the air tanks on our system between matches? May we use an
external compressor to charge the On-board tanks? May we use a separate
battery to air up an on-board tank between matches OR are we required to
use the on-board battery to charge the tanks?
Question 1: No, per !R86, "No stored air pressure intended for the
ROBOT may be located off-board the ROBOT." Question 2: Yes, provided you
are doing so in compliance with all applicable rules (e.g. !R84, !R85,
!R90, and !R91). Question 3: You may change the battery after pressurizing
any pneumatic storage tanks, but you must be using a battery plugged into
your ROBOT for the entire process per !R85. In the future, please submit
individual questions separately. This helps speed up response and make the
Q&A more easily readable and searchable. Thank you!

423
https://frc-qa.firstinspires.org/qa/423
Q423 Cutting team supplied rope
:* If at the end of a match, a robot cannot be released from the rope
for whatever reason. Would a team be allowed to cut their team supplied
rope to remove the robot from the field without a penalty?
There are no rules that prohibit a Team cutting their own supplied
ROPE. As with all other activities, please keep safety in mind if you
decide to do this.
28
429
https://frc-qa.firstinspires.org/qa/429
Q429 PWM connections
:* Is it permissible to control two motor controllers via a single
robo Rio PWM output using a Y-cable? Does this meet the R23 intent of
"directly" connecting?
Yes, and yes (assuming you mean !R73, not !R23).
29
427
https://frc-qa.firstinspires.org/qa/427
Q427 Where are the forms for 2017?:* Where's the robot lock up form? Robot inspection form?
Those forms are not yet posted, but when they are, they'll be
announced in a Team Update.

424
https://frc-qa.firstinspires.org/qa/424
Q424 Laser use.
:* We have been given a class 2 distance laser by Balluff Canada -
can we use it?
Item D in the Blue Box under !R07 specifies that any exposed lasers
other than Class 1 lasers will be a violation of !R07.
31
417
https://frc-qa.firstinspires.org/qa/417
Q417 Bumpers and velcro covers
:* There are bumpers for sale that use velcro to attach a blue or red
cover for a rapid switch. Are these FRC legal? While our bumpers will be
built according to rules, we would use a velcro attached cover for the
second color. For example, we would build traditional blue bumpers, and
make red covers that are attached with abundant velcro.
Yes, with restrictions; please see !R26-B.
32
428
https://frc-qa.firstinspires.org/qa/428
Q428 USB Camera Limit
:* Is there a limit to how many USB cameras we can have on the robot?
If there isn't a limit, are USB hubs legal.
There are no restrictions to the number of cameras allowed on the
ROBOT, nor are there any restrictions on using USB hubs.
33
416
https://frc-qa.firstinspires.org/qa/416
Q416 G09 violation caused by BUMPER contact into an open FRAME PERIMETER
:* Does G09 still apply to inadvertent/accidental damage to
mechanisms inside the FRAME PERIMETER that was caused by the BUMPER contact
of another robot? This is the first year in a while with a wide-open field
and many likely open-frame designs with rollers at the opening of the
frame. Here's an example that ignores intent like G09 implies. What if the
damaged robot made a defensive move against a high-speed robot which
inadvertently caused roller damage after contact with its bumpers was made?
Yes.!G09 applies regardless of what part of the offending ROBOT caused
the damage. Note that the rule requires the offending ROBOT to have
initiated the contact.
34
415
https://frc-qa.firstinspires.org/qa/415
Q415 Refering Q153
:* Referring to Q153: If, while not in its LAUNCHPAD, a ROBOT gently
propels FUEL a few inches above the ROBOT’S volume, into another part of
the ROBOT, does it constitute a violation of G23?
Yes, this would be a violation !G23. LAUNCHING does not have a minimum
- propelling FUEL "a few inches above the ROBOT" is still LAUNCHING.
35
410
https://frc-qa.firstinspires.org/qa/410
Q410 Manufacturer installed loop on rope for retaining feature
:* May we use a rope that has a manufacturer installed loop that is
woven into the rope to use as a retaining feature. We would then use the
loop in a Lark's Head Knot (question 142) only the retaining feature would
already exist. There would not be a knot below the davit fingers because it
is woven in a loop with an 8 inch diameter. The rope we are looking at is
one like this.
http://www.homedepot.com/p/Crown-Bolt-1-2-in-x-15-ft-White-and-Beige-Double-Braid-Nylon-Dock-Line-65782/203481778
A splice created by the manufacturer is no different than a splice
created by the Team. Please see !Q57 and !Q342 for answers regarding splice
classification and splices as part of a retaining feature.
36
412
https://frc-qa.firstinspires.org/qa/412
Q412 No arms, extensions, fuel pick up beyond original volume?
:* On page 52 of 128 in the game manual it states: "A ROBOT may not
exceed the volume for which it passed inspection during the MATCH. So a
robot that is part of Volume A as shown in the diagram on the same page is
not allowed to have an arm or other extension of any kind during the match?
Even a pickup arm that swings over the edge to pick up the fuel would cause
the overall length to exceed the 36" x 40" size. Am I misreading this?
Thanks.
A ROBOT may reach beyond it's BUMPERS during the match (see !Q4), but
**only** if it remains within the maximum allowed volume, per !R03 and !G04
while doing so. To do this, the ROBOT would have to initially be smaller
than the maximum allowed volume.
37
411
https://frc-qa.firstinspires.org/qa/411
Q411 Building over but not beyond bumpers
:* If our bumpers are at their max length, can we build over the
bumpers and start the match that way?
No. Please see !G01 and !R02.
38
403
https://frc-qa.firstinspires.org/qa/403
Q403 About purposefully fraying a ROPE in compliance with I04a:
:* If a team-supplied ROPE is purposefully frayed in a certain
section (in compliance with Q137) and the individual strands from the fray
may pull apart to a maximum width of over 1 inch depending on how the ROPE
falls during a match, but can be easily compressed by hand to less than 1
inch wide for inspection, would the ROPE still be in compliance with rule
I04a? If not, would a loop under 10 inches width made entirely out of
frayed rope over 1 inch wide in a standalone setting be legal?
Yes, a 1 in. nominal ROPE whose knotted or frayed diameter is still
less than that required in !I04, part G (as updated in [Team Update
08](https://firstfrc.blob.core.windows.net/frc2017/Manual/TeamUpdates/TeamUpdate08.pdf))
is permitted (provided it doesn't violate any other rules, of course).
39
400
https://frc-qa.firstinspires.org/qa/400
Q400 Rope/Davit retention pictorial
:* FIRST has given several answers addressing rope retention on the
Davit but still leave many wondering what is being said. Let me ask it this
way; if a flat strap or thin cord is being used as a teams rope does it
need a large 'granny' knot as the retention feature or can a loop be used
which positively engages the fingers? Suggest FIRST send out a pictorial
view/diagram showing how a loop could be acceptably used with a strap or
thin rope. This would set a standard that inspectors could follow.
Please note that !I04, part D requires a team's ROPE "be configured
such that it engages securely with the FIELD with a Retaining Feature (RF)
that does not extend more than 2 in. (~5 cm) below the DAVIT fingers."
While the Blue Box offers one way to do this (a large-ish knot that rests
on the far side of the DAVIT fingers), it's not the only way.
40
398
https://frc-qa.firstinspires.org/qa/398
Q398 Davit Dimensions - GE-17081 (Detail for -02)
:* The real field drawings for the Davit GE-17081have conflicting
dimensions which affect any rope knot retention. The detail for 17081-02
shows it as 1.00 square tubing but the material callout shows 1.125 tubing.
Which is correct?
Good catch! The material note on *GE-17081, Upper Arm* has been
corrected in [Team Update
08](https://firstfrc.blob.core.windows.net/frc2017/Manual/TeamUpdates/TeamUpdate08.pdf)
to reflect that it's 1 in. tubing.

https://frc-qa.firstinspires.org/qa/383
Q383 District Points for Digital Animation Award
:* Is the Digital Animation Award considered a "judged Team award" as
noted in Section 10.12.3.4, for the purposes of being awarded District
Points? It appears to qualify, and the awards page
(http://www.firstinspires.org/resource-library/frc/2017-digital-animation-award-sponsored-automationdirect)
indicates that it is a Team award which is handed out at the regional and
district level, however it also indicates that the award winners will be
announced prior to any competitions.
No. The intent was for District points for awards to be earned only
for awards actually judged at events, though this was not clear in the
manual. This has been clarified with [Team Update
08](https://firstfrc.blob.core.windows.net/frc2017/Manual/TeamUpdates/TeamUpdate08.pdf).
42
414
https://frc-qa.firstinspires.org/qa/414
Q414 Chairman's award video requirement
:* When submitting the application for the award. Do we have to
download the video with the application? Or can we bring and add that at
the regional?
The video is not required to be submitted on Thursday, February 9,
2017. Teams must bring the video to any Event where they are interviewing
for the Chairman's Award. Please see [this
page](http://firstinspires.org/resource-library/frc/submitted-awards) for
detailed information about the Chairman's Award Submission, including the
video requirements.
43
408
https://frc-qa.firstinspires.org/qa/408
Q408 Is an infrared device allowed on the robot if the infrared is not used
during a match.
:* Scenario 1: If an IR device and it's corresponding remote are
permanently mounted on the robot such that the IR Rx and Tx are completely
contained in an enclosure that can't communicate with anything outside of
the enclosure or robot is it legal? Scenario 2: If an IR device is mounted
on the robot such that it's IR receiver is completely covered during match
play can the cover be removed and the IR remote be used in the pit and when
powering the robot up on the field prior to the match.
We don't have enough context to be able to unequivocally rule items
legal or illegal, and the final decision as to legality of a particular
ROBOT lies with the Lead ROBOT Inspector (LRI) at each event. If you have a
question about how to interpret a specific rule or what it means, please
rephrase and resubmit.
44
406
https://frc-qa.firstinspires.org/qa/406
Q406 Do non-articulated components extending outside the robot´s count as
the frame perimeter?
:* Some of our components are fixed outside the frame of the robot
(e.g. pieces of metals, motors) but are still within the robot´s dimension
limit, even above the bumpers. Should we move this components?
Most definitely. Please see !G01 and !R02.
45
402
https://frc-qa.firstinspires.org/qa/402
Q402 Inspection
:* What paperwork does the team need to present during inspection. Is
a list of COTS materials required?
There's no explicit requirement for certain paperwork to be presented,
however note that a Team must be able to present their CAW (!I07) either on
paper or displayed on a tablet or netbook. Meanwhile, it's in the Team's
best interest to be prepared with specification sheets on any item they
believe might invite extra scrutiny from an Inspector (e.g. to prove that
an item is sold as a "servo").
46
399
https://frc-qa.firstinspires.org/qa/399
Q399 Davit member turn edge condition>
:* What is the condition of the edge on the Davit member where the
rope makes a 90 degree turn? Is it rounded off, simple deburred, or cut
sharp? This could be a serious rope fraying point.
The corner is as depicted in *GE-17081, Upper Arm*. There is no radius
to the corner about which you inquire, but the ends of all FIELD elements
are deburred. This DAVIT is also powder coated after assembly.
47
371
https://frc-qa.firstinspires.org/qa/371
Q371 Rope stowage hook & loop item
:* During most of the match the ropes are stowed with a "hook & loop"
strap, released by the Pilot towards the end of the match. This strap is
not included in the field drawings and barely mentioned in the videos. Is
the main part of the strap the hook or the loop portion? If the material of
a team's rope was snared by the strap, can the pilot lift up the strap to
free the rope?
Good point. That element has been added to [*GE-17025, Airship
Assembly*](https://firstfrc.blob.core.windows.net/frc2017/Drawings/2017FieldComponents.pdf)
per [Team Update
07](https://firstfrc.blob.core.windows.net/frc2017/Manual/TeamUpdates/TeamUpdate07.pdf).
Please see !S07 part D for the legality of contacting a "snared" ROPE.
48
381
https://frc-qa.firstinspires.org/qa/381
Q381 Using devices to lower robots safely at the end of a match
:* Are teams allowed to use additional equipment to safely lower
hanging robots at the end of a match? The desire is to take the load off of
the team-supplied rope in a way that does not rely entirely on direct human
lifting of the robot, in order to reduce the risk of injury to the person
detaching the rope. Would it be permissible to use a stool to support the
weight of the robot while a team-supplied rope is removed from the DAVIT?
Or a block-and-tackle for controlled lowering?
There are no rules that expressly prohibit a DRIVE TEAM from bringing
and using equipment to aid in placement or removal of a ROBOT from the
FIELD, provided it doesn't violate !G15, delay the field reset process
(!G02), or cause an unsafe condition (like bulky items or trip hazards).
Please note a PILOT may assist from the AIRSHIP by releasing the ROPE.

Q395 How is the rope coiled?
:* We would like to know how the rope is coiled. We know it's
deployed during the last thirty seconds of the match, but we need to know
specifically how the rope is configured. It's not very descriptive within
the manual, and we'd like some direct clarification. Thank you.
There is no detailed spec about how the ROPES are "coiled" or stowed
for a MATCH. Please see the [2017 Field Tour Video: In the
Airship](https://youtu.be/K1mM_amcQZk) to get an idea for what to expect.

https://frc-qa.firstinspires.org/qa/342
Q342 Retaining Feature
:* If a loop spliced in the end of the rope engages securely with the
field by looping around one of the davit fingers, per Q142, does part of it
need to be greater than one inch in diameter? Since the splice is not a
knot, per Q57, and the splice itself meets the specifications of a rope, is
it ok that part of the splice extends more than 2” below the davit fingers?
No, provided it engages securely with the FIELD, there is no
requirement that a retaining feature be greater than 1 in. in diameter.
Yes, per !I04, part E as updated in [Team Update
05](https://firstfrc.blob.core.windows.net/frc2017/Manual/TeamUpdates/TeamUpdates-combined.pdf)
any retaining feature may extend up to 2 in. below the DAVIT fingers.
However, while one DAVIT finger is capable of supporting the weight of a
ROBOT, it does not mean that a ROBOT is incapable of applying enough force
to damage the DAVIT finger. A team that damages a DAVIT finger will be in
violation of !G15.

Q401 Bumper Question Regarding Plywood Backing Placement and Noodle
Diameters
:* Our robot is in compliance with rule R29, but we noticed that the
plywood backings are not aligned from a side view(Some of the plywood
boards were placed a little higher than others) is this ok? We also want to
know if we are allowed to use 2.25 inch diameter noodles?
Yes, per !R23, "BUMPERS do not have to be parallel to the floor." Per
!R29-C pool noodles must be "approximately 2½ in. (nominal) round". A 2.25
inch (nominal) pool noodle would not meet this requirement.
52
393
https://frc-qa.firstinspires.org/qa/393
Q393 What does R29A mean by 3/4" nominal plywood?
:* R29A says that bumpers should "be backed by ¾ in. (nominal) thick
(~19mm) by...". Could we have clarification regarding the meaning of the
nominal portion? Most hardware stores do not sell 3/4" wood, instead
selling 23/32", with 3/4" requiring a special and expensive order. Would
small deviations from this designated thickness be acceptable (i.e. less
than 1/16" to account for manufacturing differences), or is the intent to
require a particular thickness.
Nominal lumber/plywood dimensions refer to the wood's size prior to
drying/treatment/curing, at which point the wood shrinks due to moisture
loss (this is also why a 2x4 is not 2"x4"). Lumber stores typically sell
3/4" plywood that is, in fact, 23/32" when actually measured due to
shrinkage. As long as it's sold as 3/4" plywood, it satisfies !R29 part A.

Q397 Starting in your own key
:* As long as you are still touching the alliance wall, may you start
angled in your own key?
The only requirement of !G01-E, is that the ROBOT must be " in contact
with its ALLIANCE WALL diamond plate"
54
396
https://frc-qa.firstinspires.org/qa/396
Q396 Angled Bumpers
:* R23 states "Bumpers do not need to be parallel to the floor." Does
that mean the bumpers can be angled along the side of the frame perimeter
so that the front of the bumper is facing an upward angle and extending
into the frame perimeter? Assuming the bumpers follow all construction
rules, remain inside the bumper zone and are connected as specified in R23.
No, BUMPERS must be mounted with the plywood backing nominally
vertical to meet the requirements of !R31. The quote you referenced allows
for the BUMPER to be angled relative to the floor in the left-to-right
dimension when looking at any given face of the FRAME PERIMETER (e.g. the
left side of the BUMPER could have the top at 7 in. and the right side
could have the top at 6 in.).
55
394
https://frc-qa.firstinspires.org/qa/394
Q394 Bumpers for less than six-inch side on frame perimeter
:* If a robot has a less than six-inch side extending from the corner
of a frame perimeter, would bumpers need to cover just the entirety of the
less than six-inch side or should this side be elongated to reach six
inches?
As per !R22, "If a FRAME PERIMETER side is shorter than 6 in. (~16
cm), that entire side must be protected by BUMPER (see Figure 8‑2)." Note
that this specifically refers to a "FRAME PERIMETER side", if the FRAME
PERIMETER (described in !R01) side is longer than 6", even if the "frame"
is shorter than 6", the full 6" must be protected and the BUMPER must be
appropriately backed per !R31. See Figure 8-1 for examples.

https://frc-qa.firstinspires.org/qa/391
Q391 Can you transfer fuel between robots?
:* I've seen many questions regarding G28 or controlling fuel outside
of your frame. However, I haven't seen anyone ask if unloading into another
robot is allowed. Would the brief period that fuel is being transferred be
a rule violation? Also, if robots transfer fuel while in the neutral zone,
would that be a violation of G23? Please clarify.
Please remember that we cannot comment absolutely on hypothetical
scenarios. The ultimate decision would be determined by the REFEREES at
your event, with the final call made by the Head REFEREE. However, if a
REFEREE believes that !G23 is being violated, it will be enforced.

Q389 Does current to an aesthetic device count the same as current to an
operational device?
:* Does a raspberry pi controlling lights count as an active device?
When it talks about current in the manual, does a current to an aesthetic
device count the same as a current to an operational device?
We're not completely sure which rule or rule(s) you're referring to,
but it's assumed you're referring to !R49. A Raspberry Pi controlling
lights on your ROBOT is, indeed, classified as a CUSTOM CIRCUIT per !R49
and is governed by all ROBOT rules that apply.

Q388 Bagging a second ROBOT
:* If a team were to bag a second, legal robot in addition to their
first robot, could that team then give that robot to an alliance partner at
competition, provided that the robot is inspected and identified in
accordance to the alliance partner?
No, this would not meet the requirements of !I01 which requires the
ROBOT to be "built by the _FIRST_® Robotics Competition Team". It may also
be a violation of !C04 which prohibits a Team from entering more than one
(1) ROBOT into the event.

Q387 Rules for detachment of robot from rope
:* I was wondering if there is a time limit to how long we have of
taking our robot down after it has hung? If there is, how long? And is
there any rule about sewing a layer of Velcro over a layer of ratchet strap
that is over another layer of Velcro as a rope? Velcro- Ratchet Strap
-Velcro.
In the future, please submit only one question at a time unless the
questions are directly related. Regarding your ROPE question, please use
the Search Q&A button to review the previously asked ROPE material
questions and resubmit a question specific to a particular rule if you need
additional clarification. We will not rule on particular ROPE or ROBOT
designs. Regarding your time limit question, there is no prescribed amount
of time that a DRIVE TEAM has to remove their ROPE/ROBOT after the MATCH.
However, DRIVE TEAMS should be prepared to remove their ROPE/ROBOT promptly
to allow for FIELD reset per !G02

https://frc-qa.firstinspires.org/qa/384
Q384 Does GEAR placement on an out-of-order GEAR SETs matter?
:* There is some confusion around the word "installed" w.r.t.
individual GEARs in section 3.4.2. "ROTORS only start if GEARS are
installed in ROTOR order". Does it matter if higher-order GEAR SETs have
GEARs installed before low-order ROTORs are installed / activated? E.g., if
ROTOR 2's GEAR SET has no GEARs placed on it, and a PILOT places a GEAR on
the GEAR SET attached to ROTOR 3, then places all required GEARs on the
GEAR SET for ROTOR 2, will ROTOR 2 still activate after turning 3 times?
Please see [Team Update
07](https://firstfrc.blob.core.windows.net/frc2017/Manual/TeamUpdates/TeamUpdate07.pdf).
The placement of GEARS within a GEAR set, or across GEAR sets, is
inconsequential. Remember, however, that once a ROTOR has started, any
GEARS used to start it cannot be removed per !H10.

https://frc-qa.firstinspires.org/qa/382
Q382 Is rope with multiple I04.D techniques legal?
:* From I04.D: "A ROPE must... D. consist entirely of flexible,
non-metallic fibers sewn, twisted, tied, woven, knitted, crocheted,
intertwined, or braided together" A tight interpretation of "or" allows
only one of the above options. A less strict interpretation could allow any
or all of the options. A strict interpretation would disallow all of the
above techniques with typical COTS woven, non-adhesive, sew-on
hook-and-loop strips, as the strip itself was woven by the manufacturer.
It is not the intent of the manual to use an exclusive-OR relationship
with any use of the word "OR," unless specifically noted.

https://frc-qa.firstinspires.org/qa/380
Q380 Section 3.9 - Touchpad
:* In the latest update section 3.9, it is stated, "...less than 75
pounds of pressure..." General usage (albeit incorrect) of pounds of
pressure would indicate pounds per square inch of pressure. Since pressure
is force times unit area, I believe that you meant to write force, not
pressure.
Good catch. The manual has been updated per [Team Update

Q368 Alliance Wall to Baseline and other Measurements
:* I was wondering what the official distance was from the alliance
wall to the baseline I seem to see conflicting information. The rule book
says 9' 4" but the drawings I printed says it is 2x 93.3. and the same goes
for the distance to the launchline. Also I am wondering how big one of the
sides of the base of the airship is. From what we are gathering it is just
under 40 inches is that correct? Thanks
The purpose of this Q&A is to answer questions regarding the rules of
FIRST STEAMWORKS. Any measurements or materials information can be derived
from the Field Drawings available at:

Q360 May a robot include fabricated items from another team's tagged bag?
:* R21 specifically allows teams to use fabricated items from another
team's withholding allowance, but not from their robot bag (or bags). R15
through R20 do not appear to explicitly forbid use of fabricated items from
another team's bag, but the use of "their robot" and "your robot"
throughout these rules imply that the parts in a team's bag may only be
used on their robot. May a robot include fabricated items from another
team's tagged bag?
Yes, a ROBOT element that was bagged "by 04:59 UTC on Stop Build Day,
Wednesday, February 22, 2017" meets the requirements of !R15 regardless of
which Team's bag it was in.

Values V1., #41 -Section 4 MATCH Play 4.1 Periods V2, and #44 -Section 4
MATCH Play Table 4-1 FIRST STEAMWORKS Rewards V2 What does the robot have
to do in Auto to get the points? Does the robot have to "cross the
baseline" completely or does part of the bumper just have to "break the
baseline"?
There are several ways to earn points during AUTO, per Table 4-1. For
the "AUTO mobility" points specifically, a ROBOT'S BUMPERS must break the
vertical plane defined by the BASE LINE before the end of AUTO.

Q255 LIFT specifications (spring source and shaft collar)
:* In testing the McMaster spring order called out in the field
components (9664K68) to one from century with identical specifications
(http://www.centuryspring.com/extension-springs-e-41.html) substantial
differences were found in deflection and springiness. Will all field spring
be solely sourced from McMaster? Additionally, the field tour video shows a
collar, while field components drawing does not.
All FIELD springs have been sourced from McMaster-Carr, however
Practice Field springs and springs used as spares for official fields may
be an alternate part (and if so, we'll update the manual and publish in a
Team Update when that information is available). Regarding the collar, the
[Field Tour Video](https://youtu.be/ZeOevMTC_rw) is correct, and has been
added as of [Team Update

Q378 Cost Accounting - R10(B) KOP clarification - "Yellow Tote" items
obtained by other means
:* Does R10(B) exclusion apply to "Yellow Tote" items even if we
didn't get them from a "Yellow Tote" ? We used some parts from previous
years and bought some parts directly from AndyMark later. Are they exempt
or listed at full retail value?
Any item that meets the definition of KOP, even if your team did not
acquire it that way (with the exception of PDV items which require your
team to have acquired them in a specific manner to qualify as KOP) may be
omitted from the CAW, or listed with a $0 cost per !R10-B.

Q377 Does the bumper have to be the same length as the frame b4 the frame
returns into the robo
:* Figure 8-1 top image shows an opening of the robot. The top right
frame is >=6 so the bumper is >= 6". If the frame was 9" but the bumper
still satisfied the >=6 would this still be legal? This image looks to have
a 1/2" of frame before "not a Bumper". This edge is somewhere between the
not ok second image and the >=6" in the same image. If you envision the top
image top two bumpers, between these bumpers 2" past the end of the >= 6"
bumper the frame 90deg returned into the bot 4" with a 10" gap
The "ROBOT frame" has no impact on compliance with !R22 except to the
extent that it defines the FRAME PERIMETER. The presence, or absence, of
"ROBOT frame" in sections of the FRAME PERIMETER which do not have to be
covered with BUMPER to comply with !R22 do not change legality.

Will we be penalized if our robot unwinds itself because it has been turned
off after the match is over? 2. Can we lift the robot to unhook the rope
that our team will provide and take our robot off the field with the rope
still attached? Thanks!!
There is no penalty for a ROBOT that descends once DISABLED at the end
of the MATCH (although the "Ready for Takeoff" bonus may not be granted if
requirements outlined in *Section 3.9 TOUCHPAD* aren't met). Please see
!Q300 for the second part of your inquiry.

Q362 Multiple launchers
:* Any restrictions with multiple launchers on a single robot to
project fuel?
We cannot rule absolutely on hypothetical ROBOT designs, and the final
decision as to legality of a particular ROBOT lies with the Lead ROBOT
Inspector (LRI) at each event. However, there are no rules prohibiting
multiple devices capable of "launching" FUEL on a single ROBOT, provided
all other ROBOT rules are satisfied.

Q357 Climbing and the bumper zone
:* When it come to the climbing rules, when it says "Example 1: A
ROBOT that is at an angle while navigating a ROPE has its BUMPERS outside
the BUMPER ZONE. If this ROBOT were virtually transposed onto a flat floor,
and its BUMPERS are in the BUMPER ZONE, it meets the requirements of R23."
Is the transposition in reference to the field floor, or the bottom of the
robot? Thanks.
The transposition described in the example is virtually "undoing" any
rotation and displacement caused by climbing the ROPE, but **not** undoing
any changes to the ROBOT itself. This means that a ROBOT that does not
change shape at all while climbing, but rotates so the BUMPERS are
perpendicular to the floor does not violate !R23 because the BUMPERS would
be in the BUMPER ZONE if this ROBOT were place back on the flat floor. If,
instead, a ROBOT starts pushing a mechanism down against the floor, lifting
itself up onto the ROPE, but also taking the BUMPERS outside the BUMPER
ZONE this would violate !R23 as the BUMPERS are now outside the BUMPER ZONE
even when the ROBOT is place on a flat floor.

Q365 Actuators limitations

greater than 1 in. (nominal) stroke and rate electrical input not greater
than 10 watts (W) continuous duty at 12 volts (VDC). We currently an
AndyMark 3515 but its stroke is 50mm...illegal?? or Legal?? If Illegal,
where can we get one that is Legal??
We will not rule definitively on individual ROBOT parts. We will note
that the referenced part is sold as a "linear servo" and is not an electric
solenoid actuator.
76
369
https://frc-qa.firstinspires.org/qa/369
Q369 Is a servo a servo a servo?
:* To me this is simple, but there seems to be some difficulty on
Chief Delphi, so here are the questions: Traditionally, servos are
rotational devices which provide rotation-angle internal closed-loop
control but do not provide feedback for "external" control. Are devices
sold as "linear servos" which provide linear motion using servo standard
PWM controls but producing linear rather than rotational motion considered
servos under the 2017 rules?
If it is sold by a VENDOR as a "servo", linear or otherwise, it's a
servo.

Q370 ROBOTs adhering to GAME PIECES?

https://frc-qa.firstinspires.org/qa/376
Q376 Non-metallic, non-fibrous debris in/on rope
:* During our climb practice, we noticed that small (< 1mm)
non-metallic but non fibrous pieces of the robot tore off the robot upon
removal of the rope from the robot, and the debris became embedded in the
rope. This debris does not provide an advantage to subsequent climbing. We
are planning to use a team-supplied rope. Would the presence of such debris
render the rope unusable in match play until it is completely removed?
We cannot rule absolutely on hypothetical ROPE situations, and the
final decision as to legality of a particular ROPE lies with the Lead ROBOT
Inspector (LRI) at each event. When in doubt, however, Teams should ask for
the ROPE to be re-inspected.

useage? The am-2971 states that the motor is a banebot RS775 series but
nothing more specific as identified in R32?
The legal motors are listed in Table 8-1. If you're not sure of a

Q374 Did Team Update 05 change the comment in the answer to Q142?
:* The second paragraph of the answer to Q142 reads "Please note that
placing any knot used to form loops, as described above, below the DAVIT
fingers would violate I04-F.". However, Team Update modified I04-F such by
appending "with a Retaining Feature (RF) that does not extend more than 2
in. (~5 cm) below the DAVIT fingers." Provided that the knot was within 2
inches of the DAVIT fingers, does this update modify that second paragraph?
If not, why not?

penalized so we are not either" G24 Don’t throw GEARS This one may put the
stop to it BUT WOULD IT? G21 GAME PIECES: use as directed... but "Return
LOADING STATIONS" are not listed?
Just like in the answer to !Q166, please note that deliberately
placing GAME PIECES in front of any FIELD elements (for example, but not

Q372 Weighing bumpers during inspection
:* Assuming R25 compliance, may the robot be weighed WITH the bumpers
on during inspection? In other words: If the entire robot+bumper assembly
weighs less than 120lbs, can it be asserted that the robot would weigh less
than 120lbs without the bumpers?
No. The ROBOT and BUMPERS will be weighed separately to assess
compliance with !R05 and !R28.

Q367 Perimeter protrusions
:* Under Sec. R02, will small extremely flexible plastic members,
such as wire tie tails up to maybe three inches long, be considered "minor
protrusions"?
We cannot rule absolutely on hypothetical ROBOT designs, and the final
decision as to legality of a particular ROBOT lies with the Lead ROBOT
Inspector (LRI) at each event. A protrusion that is 3 in. long is very
unlikely to be considered minor.

Q364 Winch Motor Legal?
:* Under rule 8.6(Motors and Actuators), would a motor on a purchased
winch be considered to be a "Select Automotive Motor" and therefore a legal
motor?
No, a winch motor is not a "Window, Door, Windshield wiper, Seat,
Throttle" as listed in !R32, and thus not permitted.

Q363 Breaking the Baseline at the Middle Lift Station
:* Is it possible to break the baseline at the middle lift station.
For example, if a robot were to drive from the alliance station wall
directly to the wall of the middle airship lift, would that robot earn the
mobility points for breaking the baseline in auto?
Yes, it is possible to break the BASELINE at the middle LIFT position.
However, the ultimate decision would be determined by the REFEREES at your

Q306 What level of fraying constitutes damage under [G15], and when would
it be called?
:* In our hook-and-loop winch drum tests many of our ropes fray, and
how much seems to depend on many factors. The fraying in some tests happens
a few fibers each time. In other tests, the fraying is more obvious. Is any
level of fraying considered normal wear and tear? To a referee what
approximately separates damage from wear and tear with respect to fraying
while interacting with any robot component (hook-and-loop or not). At what
point in the match would [G15] be called for fraying?
We cannot comment absolutely on hypothetical scenarios. The ultimate
decision would be determined by the REFEREES at your event, with the final
call made by the Head REFEREE. There is no *FIRST* Robotics Competition
specific definition of wear-and-tear, if the REFEREE(S) determine the
damage is the direct result of a ROBOT action or MECHANISM it is possible
that !G15 would be called. Teams should design carefully to ensure they do
not cause any damage when attempting to climb a FIELD ROPE. If you're not
referring to a FIELD ROPE, please see !G15, as updated in [Team Update

:* Section 9 (inspection & eligibility) does not give any indication
on how robots will be inspected for compliance with R03? Will it be a tape
measure, do tolerances exist? If it will be an inspection box, can/will
FIRST release the box specifications? If a box is used, what will be the
criteria of passing inspection. e.g. 1. Robot not touching the box at all.
2. Robot only fits the box with extreme compression of bumpers. This is
information teams need to know to ensure they pass inspection.
A ROBOT that requires "extreme compression of the BUMPERS" to comply
with !R03 does not comply with !R03. ROBOTS must fit within the volume
specified in !R03; teams should not be counting on any particular procedure
or tolerance to make sure they fit within that volume.

Q353 Using Hinges on Bumpers
:* As said in R29:F, you are allowed to use aluminum brackets to
fasten bumpers together at a 90-degree angle. Would it be acceptable to use
a metal hinge for the same purpose, given that both bumpers will be
fastened to the frame 90 degrees from each other?
No, hinges are not aluminum sheet or angle and thus do not meet !R29-F.

Q325 Game Pieces Transfer from Loading Zone to Alliance Station
:* Ref section 4.6, "GAME PIECES that roll, slide, or otherwise
transfer from a LOADING LANE to an ALLIANCE STATION (or vice versa) are
considered “owned” by the ALLIANCE in the space now occupied by the GAME
PIECE. " What constitutes a GAME PIECE to "occupy" the Alliance Station.
Must the GAME PIECE complicatedly be in the volume of the Alliance Station,
or is "breaking the plane" (i.e. football touchdown) satisfy the "occupy"
standard?
A GAME PIECE is considered available to an ALLIANCE if any part of the
GAME PIECE is breaking the plane of the ALLIANCE STATION volume. However,
per !H07, DRIVE TEAM Members may only contact the portion of the GAME PIECE
that is inside their zone.

Q338 Touchpad force leeway?
:* This question is similar to #219. My team would like to know if
there is an additional leeway to the 1-3 lb force to trip the touchpad. For
example, if we are 1-2 pounds over (or several) when we stop climbing the
rope will this damage any of the field components?
We believe !Q219 answers your question. If it does not, please
rephrase your question and resubmit. Please use the Search Q&A button on
the navigation bar before posing a new question.

Q301 Knitted fibers for Rope?
:* I04-D permits non-metallic fibers that are "woven". Are "knitted"
fibers permitted? While similar to "woven", there is a technical difference.
Yes, "knitted" fibers are permitted. Please see [Team Update

Q299 Damage to Team Provided rope.
:* With regard to R06 - R09 and Arena Damage -- If there is picking
and fraying caused by Velcro hooks on the climbing spool to the teams rope,
but no other field element is damaged is this a violation of R06 - R09? We
understand our rope might be subject to re-inspection and might have to be
replaced with a fresh rope. GDC says "Why did we let them bring their own
rope" :) -- Thanks for all you do!!
We actually don't feel like we need to govern what happens to Team
supplied ROPES. Please see [Team Update
06](https://firstfrc.blob.core.windows.net/frc2017/Manual/TeamUpdates/TeamUpdate06.pdf).

Q219 What is the maximum force a robot can apply to the touchpad when
climbing?
:* As per section 3.9 in the manual. Teams may wish to consider a
reasonable “safety factor” for TOUCHPAD activation and assume that no more
than 3 lbs. (~1.4 kg) of vertical force is required. Does this mean the
maximum force that can be applied is 3lbs when lifting a 120lbs robot? If
not what is the maximum force that can be applied before damage will occur
to the touchpad?
Please see [Team Update
06](https://firstfrc.blob.core.windows.net/frc2017/Manual/TeamUpdates/TeamUpdate06.pdf).

Q323 District teams 6 hours bag unlock for back to back districts
:* For teams who have back to back districts (Districts 2 starts the
day after District 1 ends), will a combined 12 hour window of our of the
bag and tag be allowed?
Per !R19, District teams may only use the ROBOT Access Period for a
total of six (6) hours during the 7-day period preceding any 2-day event in
which their Team will be competing with their ROBOT. Since your events are
back-to-back, the 7-day period preceding each would overlap, and if you
wish you may use both six (6) hour access periods during that overlap, for
a total of twelve (12) hours.

Q352 Picking up fuel in auto.
:* Provided that a robot never has more than ten fuel at any moment,
can a robot A. pick up fuel in auto and B. score said fuel in the boiler.
Also if a robot can pick up fuel in auto, may it pick up more than ten at
one time and score them?
!G01-F applies only at the start of the MATCH. Once the MATCH has
started, there is no restriction on the number of FUEL a ROBOT may possess.
Therefore, A) yes and B) yes.

Q351 Entry on Cost Accounting Worksheet
:* On the sheet is it enough to put Chassis Kit 2 - Axle Bolt
(orange) for the description and KOP for the Source or do we need to
itemize each item that is in that Kit?
Per the Blue Box below !R10, "If the item is a KOP item, it does not
need to be on the CAW."

Q350 robot extend over bumper
:* the robot hopper is being designed to extend over the bumpers, but
not past the bumpers. Is this allowed if we stay within the parameters of
the assigned volume space.
We cannot rule absolutely on hypothetical ROBOT designs, and the final
decision as to legality of a particular ROBOT lies with the Lead ROBOT
Inspector (LRI) at each event. Please consider !R02.

Q348 About the use of a pixie camera
:* We are new to this competition and we were wondering if we could
use a pixy camera as a part of our hardware since we believe it could be
useful for our design our options are Pan/Tilt Kit for Pixy CMUcam5 Image
Sensor or Pixy CMUcam5 Image Sensor Thanks for your time.
There are no rules that govern what kind of camera that may be added
to a ROBOT. However, pay special attention to !R36 with respect to any
Pan/Tilt mechanism.
