TimestampWho are you?What Sub-team?What was done this meeting?What needs to be done next meeting?
11/29/2017 20:15:02Julia FrothinghamSoftwareWe debugged some of our drivetrain code and confirmed that our claw code works. We need to put the robot on the ground and drive it around to test more of our drivetrain code, specifically our deceleration code and reverse code. As soon as the arm gets put on, we will test our arm positioning code and start to test our autonomous routines. That may not all happen next meeting.
11/30/2017 18:56:04Julia FrothinghamSoftwareMerged code to be ready to debug arm code. All the debugging. We know our drivetrain code is mostly good, but we NEED to debug and calibrate our arm code and autonomous routine.

1/9/2018 14:04:07Jennifer YangDesignThis is for the meeting yesterday (1/8/2018). We decided on our drivetrain. After debating between a 2 CIM shifting gearbox and a 3 CIM single speed gearbox. We wanted a maximum speed somewhere inbetween 11 and 13 ft/s. However, if we use a shifting gearbox, our lower speed would be too slow and not useful to our team. So, we decided to choose a 3 CIM single speed. We choose gear ratios of 11:40 and 24:42, resulting in an overall gear ratio of 6.36:1. This gives our drivetrain an adjusted speed 11.84ft/s with a current draw of 62 Amps per motor. We were able to complete the gearbox plate and we will proceed to create the gearbox assembly next. We are going to be using west coast drive, with six 4” colson performa wheels and a drop center. We have yet to decide our wheel width. We also decided on a wider configuration, having our front and back driverails be 32” and our side driversiled be 28.” This will give us more electrical space and although we have limitations with our CNC Jet machine lengthwise, we know of a machining process that will allow us to get around that issue. With a 30” limit and the 32” rail only having mounting holes, we should not have any issues as we might with creating bearing holes on a piece of 2x1 longer than our CNC machine can hold. We need continue working on the gearbox and drivetrain assembly.
1/9/2018 17:56:30Henry FowlerElectricalHephaestus was disassembled and materials were put away from FIRST Choice and other sources.prototype review and if there is time determine what components will be necessary for the bot
1/9/2018 18:49:12Julia FrothinghamSoftwareLaptops were updatedFinish up a few updates, finish drivetrain code
1/9/2018 19:02:35Jennifer YangDesignWe worked on assembling the gearboxes. We decided on an open frame and we’ve created the basic frame for the robot. We chose a 1/16” drop center to allow us to go over the cable bumps with minimal tipping. We know the bearing hole placement and chain calculation. As of right now, we have decided to keep the manipulator for the power cube within the robot’s frame perimeter instead of having one that rotates out.We need to continue working on the gearbox and drivetrain assemblies.
1/10/2018 19:07:07Julia FrothinghamSoftwareCode imported onto laptops. Assisted with prototyping of grabber mechanism.Continue prototyping assistance, begin work on autonomous depending on Bunnybot availability
1/10/2018 19:57:53NupoorDesignBellypan created and put on drivetrain frame.continue working on drivetrain frame.
1/10/2018 21:03:24Jennifer YangDesignWe continued working on the drivetrain. I worked on modifying the rear shaft for the encoder. Brooke and Josh both worked on creating shafts and adding to the assembly of the drivetrain. Nupoor worked on creating the basic bellypan for the robot. It is unfinished and will need to be modified accordingly to account for cutouts. We need to finish the drivetrain and meet our deadline!
1/12/2018 6:46:52James ChaplenElectricalFor meeting on the 10th: For the Skeleton Board we placed down the Power Switch, PDP, RoboRio, VRM, PCM, 2 Talon srx, and wired the CAN BUS for these components as well as the power wires from the Talons, VRM, and PCM. Wire power wires from RoboRio to the PDP, Wire up the Power Switch to the PDP, and maybe attach a camera with ring light.
1/12/2018 17:11:54Henry FowlerOtherBelt intake- We assembled a very sketchy prototype, and determined that it wasn't close enough to tolerances to be functional. This demonstrated that wheel intakes were better in at least one way- they're simpler. We couldn't think of any advantages to the belt intake over the wheel intake so after a vote this idea was dismissed and the prototype was disassembled.The Belt intake prototype is over so now my members and I will work on the gripper prototype.
1/12/2018 19:27:21Henry FowlerOtherGripper claw- We brought BunnyBot back up online and tested its claw with the power cube. Even with a claw designed to hold bunnies and buckets it still worked reasonably well. It could drive directly forward and backwards without losing the cube even at high speeds. It could also hold the cube while rotating, while at lower speeds, but it couldn't really take any direct impacts or else it would drop the cube. This is definitely proof of concept.We have provided proof of concept so this prototype group will now be finished.

1/12/2018 22:51:32Jennifer YangDesignWe finished the drivetrain! (Well, as much of it as we can do right now at least.) We started working on drawings for the shafts and compiling an order list for the drivetrain parts. We need to look at how the other components of the robot will be integrated. We also need to finish making drawings and the order list.
1/13/2018 18:44:43Julia FrothinghamSoftwareBasic 2018 drivetrain code tested on cardboard. Firmware flashed on various components. Auto routines written for Bunnybot testing.

1/13/2018 22:53:15Jennifer YangDesignWe started on bumpers, the elevator, and the power cube intake mechanism. We decided on a 4 stage cascading elevator with 28” long pieces for each stage so that we can get to a height of 88” (6” overlap). We need to decide what motors to use for the cascading elevator, figure out gear ratios for our gearboxes, and continue working on the elevator and power cube intake mechanism.
1/15/2018 16:42:11Henry FowlerElectricalCalculated power consumption for the robot, tested the Talon SRX and tried one possible fix that didn't work, IR sensor research, some reorganizing, teaching some new skills, communicated about 3d prints, some fixing broken stuffCircuits for the field- long term, check on board layouts possible
1/15/2018 17:27:45Jennifer YangDesignI worked on figuring out the belt loop for the wheeled intake as well as CADing one of the tubes.I need to figure out how to mirror the other tube and figure out how the mechanism to drop the intake down will be implemented.
1/15/2018 18:22:53Julia FrothinghamSoftwareWe wrote and tested auto routines for 2018 using Bunnybot. We ran connectivity tests with some upgraded laptops. We began to edit our Bunnybot code so that it can be used with the 2018 control system.Continue upgrading Bunnybot code. Write code for other functions of the robot.
