TOM Tri-Track dual servo robot tank chassis
by krux, published
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.
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.
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.
