Gearbot

10/17/2018 I had to redo the frame again, seems to work OK now.

10/10/2018 The gear was binding a bit so I increased the distance between the gear and the wheels on the frame. It is also a bit tricky to assemble due to the location of the screws.
This robot requires additional parts and programming. See my Dumbot robot for details.
6-32 x 3.4"

10/25/2018 Changed the size of the hub to prevent binding and allow for better motor motion.
