Here is the basic layout of the components I want in the bot. In its most simple case the components needed are.
- Drive system (connecting motors to tracks)
- Control Electronics
The first step that I made was trying to find out how to make the tracks, I figured that this would determine the relative size and shape of the Bot. Here are some of the resources that I have been using.
The RC tank combat group has some tutorials on different methods of making tank treads for their robots including using bike chains, old treadmills, conveyer belts etc… They explain a lot on their how to pages. link
They also have a section on casting some tank tread Pads with PMC-790 urethane rubber from Smooth-On. link
Another idea was to use timing belts I borrowed a catalogue that had belts by a manufacture called Browning. The most promising results came from their Poly-V line-up, sadly when I went online to find prices everything seemed to cost around $70-$80 per belt. Browning had Grip band belts (also expensive). I did manage to find a drive train belt that was 1 3/8″ wide. link
Goodyear also has their Gatorback belts, these are like the Browning Poly-V belts but cheaper, its vey hard to find widths of these belts
