Notes

OSE Linux used for workshop build
UEFI/BIOS Boot Loader compatibility issues need more instruction and possible resolutions.
Long term Schedule after tractor workshop is more open besides international trips.
Potential South OSE branch in Central and South America
HeroX platform usage testing and expansion
Improving Developer Recruitment and Management via timesheets
MicroTrac detail updates in CAD
Gazebo Open Source Vehicle Simulator being used for microtrac testing see slide
Vibratory Plow design use ½” plate, more eccentricity for weight, see slide
New style of motors on microtrac and valve system allows faster speed for microtrac 3 or 9MPH in series
Right angle fittings under tracks are tight maybe motor turn downward to make routing less likely to get damaged
Motor mount box clearance on top or bottom
Larger existing motors are reused on the bigger LifeTrac
Bobcat Quick Attach may need more bracing between plates
Second Power Cube and control mounting ergonomics for walk behind operation
Power Cube frame to 13” from ~10” to fit motor easy
Quick Attach arm mount points could be reshaped to round off corners leaving ¾” material around hole in ½” plate is sufficient
Cylinders for QAttach are larger with 1” pin mount holes matching other hole mounts
Some new DXF’s need to be made for parts that are being made in workshop, some existing parts are being reused.
Continued long term work on OSE Coin that returns dividends to members discussion on slack channel https://join.slack.com/t/osedevorg/shared_invite/enQtMjUxNjkxNjgyNjQ2LWUxMmFkNTMwZWNlNGFkYTNmMzYwNjRmOWUzYjNlYWQ1MTlhMjk4NmQ2MGRlMTg2MmIxZjIwYTdlYWEzYTI0N2Q
LifeTrac - 1. Narrow loader arms to fit Bobcat quick attach 2. Fit 36” cylinder 3. Fit 24” cylinder. -Abe
Microtrac - 1. 1” pin holes, 2. Trim mount of quick attach 3. Trim motor mount 4. Generate fab drawings
Availability for CAD work assignments for tractors Abe, Dixon, Roberto
FreeCAD OSEDev WB work in python http://opensourceecology.org/wiki/OSEDev_Workbench - Oliver
Make Fab drawings with dimensions for visual build instructions to be used in workshop see next slide
Find old instructions or create or break down components into sub parts for making fabrication drawings
Still need solution or work arounds for USB connectivity issue in OSE Linux for using arduino and 3DP software chain

Notes:

OSE Linux testing: issues

Discussion about specifications of the minitractor design, while showing the CAD File.

Focus job on the tractor, current state of the tractor.

Not technically acurate:

Motor is up,

Mounting plate is not correct

Path array draw a line, etc. (FreeCad knowledge)

42 inches

Make 9 inches the tracks

Tracks are not lind out with the idlers

Shaft is looking good….

20 inches height of the power cube…

Shaft goes the whole way to hold loaders

To Do: make a Geometry to put the loader

Because the tracks are so height on the back there is not so much space,

Requirement: put the center of gravity as low as possible

Missing the idlers: need to be tensioned

Put a shaft through the middle of the frame or under the frame, or through the frame;

Mount two motors so that : assembly mount the motor on some ckind of a plate against the vertical so that …lower the sprocket all the way down, take a pin and then connect the track,

34 tracks; put 40 , sprocket is sticking too much..

Bobcat standard

Next Steps:

Promo video October 30; still doing the filament maker

Experimental torch build; October 14 -15 Saturday Sunday;

Change in the setup of workshop, 1sst half day, focus on manipulating freecad and generate drawings

Heavy duty: 200 pounds milling/ force, belt drive for heavy duty machines.

Calculations indicate that is possible that you it can be slower,

But speed of machining throughput, produce 1 per day…. Low Volume production

This is the value proposition

Previous build: heavy duty drills…Main take away: We know how it works, use hydraulics for the heavy duty motors, and stepper motors for the drives on the axis,

200 pounds per inch of belts, duplication or quadruplication of belts, using the same universal axis…. Core technology universal Axis…

New workflow to generate full exploded views…

Roberto: This procedure is easier

Problem quality of the image,

It should be possible to improve the image quality

Workflow for importing assemblies

Is the power cube and assembly or separated in parts;…

Keep it as a one part;

Gasifier: Talked to someone: We are still planning for gasifier, smaller version with better carburetor, click to see the notes, print in ceramics. Printing clay, Print the core of the gasifier, is a very high temperature carbon monoxide, charcoal is the fuel, it burns… is very high temperature….

Discussion about the OSE linux:

Problem to download, bandwidth limiter, in chromium,

Not well provided links for Christian

Michel: wokflow of 3d parts webgl is being still develop

Problem Freecad doesn't export MTL file

Find developer Python;

Questions/Comments

MT Motor hose routing looks better underneath for front power cube. Above debris caught in tracks may more likely to cause damage in the tight space.
Can we reduce the length of the QA female plate in order to fit the commercial QA male plates? The length of the commercial QA female plate is 45”, and instead of fit it to the bucket, we can fit it to the QA male plates.-roberto
Just from looking at the MT CAD that toothbar looks time-consuming to build. I think cutting a sheet in half with a tooth pattern such that you make two bars might be faster and almost as effective. Not sure how fast a human could cut that obviously for CNC that would be easy. Maybe cutting it out of thinner material and then bolting both pieces to the bucket would work ok too.
