Simple Tank Platform
thingiverse
This is a simple differential drive, treaded platform for toy/robot base. It uses 2 standard TT motors and 3D printed treads (TPU). The design is largely symmetric, and can thus drive upside down as well. Additional parts required: - (2x) TT motors (https://www.adafruit.com/product/3777) - (4x) 8x22x7mm bearings - (4x) M3x30 bolts - (4x) M3x10 bolts - (8x) M3 nuts - Drive electronics, batteries, remote control Print 2 of each part, except for base/base2 (print 2 total) and tread1/tread2 (pick one). Embed bearings while printing into cup and idler. Then press-fit cog and idler_shaft, respectively. Use the slots in the idler_shaft to tension the treads.
