To answer the most pressing question, the mecanum has missing parts because... they were accidentally deleted from the model in my library.
Now about the design, I originally based this module off a picture of 1540's drivetrain from this past season.
They had quite a bit of lightening done on the module and originally I thought their strut thickness was .25", but looking at it again, it appears closer to .5".
I was figuring that the struts were on the thin side.
My reasoning for the wheel sizes was that A: my team owns 6" mecanums from this past season.
And B: I wanted to keep the connection point for the piston as close to the traction wheel axle as possible without needing a longer piston or having a larger radius of rotation for the traction wheel.
However in doing so, I overlooked the fact that the mecanum and the traction wheel need to be at very different speeds
So the next iteration should have a smaller traction wheel.
Yes, there is enough room to run the belt past the stand-offs. The belt is c-c and a tight fit. So there shouldn't be much drooping in the belt.
There is a decent amount of clearance around the 24 tooth pulley.
The actual gearbox system will be very similar to
this set-up.
I'll post the next version after the weekend when I have some time to work on it.
Thanks for the feedback everyone!
