Robot Tank Base

A general base to use for robotics projects etc. To keep the cost down it doesn't use any bearings. The tracks are assembled using Brad nails. The axles are 1/4" aluminum round stock from Home Depot.

I'll get together a list of the remaining screws in a couple of days.

Update:
Added Modified Side panel to direct mount the motor using Pololu Hex wheel adapter. Added modified sprocket that works with the Hex wheel adapter.
