Robot Base II

This is a work in progress that I'm using to further my understanding of designing and printing tank tracks using TPU. This works as is right now. I have found that the motors are a little underpowered to handle the tracks I've included, so I plan on generating another set that should improve performance and power usage. I also intend on building a cover for this to hold a Raspberry pie and some sensors.

3/25/17 Edit: added new track profile 1b. The Motors have a much easier time with it.

Parts List:

2 - Pololu micro motors.
2 - Pololu M3 hubs
2 - Pololu simple motor controllers (future)
1 - Raspberry Pie (future)
4 - M3 x 30mm screws bolts and 8 washers (attach chassis to arms)
8 - M3 x 5mm screws (for the hubs)
2 - 1/4" x 1 3/4 inch bolts for the idler pulley
4 - 1/4" inside diameter bearings for the idler wheels
