TOM Tri-Track dual servo robot tank chassis

thingiverse

This is a varient of http://www.thingiverse.com/thing:14599 by Ktronics. The Tri-track frame is too large to print on a Thing-o-matic, so I've updated the design to split the frame into three parts which can be bolted together. I've also updated the drive wheels to include holes for mounting the servos, mounting holes in the frame for the servo mounts. As well as updated the servo mounts to be the correct size for the CSRC-311 servo. http://youtu.be/hBeYp6AdOhc The file "Stationary.ino" is a basic Arduino sketch which reads distance from two PING sensors, and does obstacle avoidance. It's named "Stationary" as that is my robot's name. He spent awhile without a brain, and thusly didn't move all that much, thus the name. Instructions Print the following components: 2 - Tri-Track frame end segments 1 - Tri-Track frame middle segment 42 - Track Sections 2 - drive sprockets 4 - 608 idler sprockets 4 - 608 Bearings 2 - Servo Mounts The following hardware is required to assemble: 42 - M3 x 45mm socket cap bolt 42 - M3 nylon-insert hex locknut 8 - M3 x 15mm socket cap bolt 4 - M3 x 20mm socket cap bolt 6 - M3 x 25mm socket cap bolt 32 - M3 washer 4 - M4 x 16mm socket cap bolt 8 - M4 washer 2 - M8 x 160mm threaded rod 20 - M8 hex nut 16 - M8 washer Hardware can be found online through McMaster-Carr.
