I don't have a picture. But this is how it worked. We built 4 drive modules that fit inside of our robot and could easily slide in and out of the fram of the bot.
The modules were all conected to a central point by hinging peices of metal together. There was one piston that ran up the center of out robot. When that piston expanded, it pushed on the central point causing the peices of metal to hinge outwards and expand the overall lenght of the 2 pieces connected to each other. Each module had its own 2 piece of metal that were hinged together that met up at a certain point. So when the piston pushed down, the drive module were pushe out of the fram of the bot.
Forgive me if the explanation is bad. I am too tired to think properly.
