Sumobot Chassis v2

3D model description

This is the next iteration of my original sumobot design.

A few changes:
* It\'s made from three pieces, not one
*It uses two solarbotics GM8 gear motors (actually the pololu 120:1 equivalent), instead of continuous servos
* It works.

I\'m really happy with how it came out.

I\'ve updated the files since I first posted this thing. They\'re pretty small tweaks but they really help when trying to wire up the whole thing and hold down the electronics.

I've posted a video of it in action. It still has no opponent sensing/detection but it's staying within the white space perfectly. See it here:

Stay tuned for thorough instructions/code and possibly a chassis kit for sale at

3D printing settings

Print one of each part.
Bolt things together with m3 nuts and bolts.
Wire everything up.
Have fun!
