Difference between revisions of "Caterpillar Robot (Q44718)"

This caterpillar track is the first step towards designing and building a printable mobile robot. My finished robot will have four of these modules, but many other designs are possible. A single caterpillar can function on its own as a simple robot that can move forwards and backwards; two modules can be joined together to form a tank-like machine, etc. This thing is designed to work with a Futaba 3003 servo (modified for continuous rotation) and uses O-rings to make up the transmission and the caterpillar itself. Transmission O-ring: 3mm thickness, 60mm diameter Caterpillar O-rings: 3mm thickness, 124mm diameter This O-ring system was chosen because it was easier to prototype, but it has evident drawbacks. In future revisions I will change it to a "solid" rubber track. Note that the pictures of the printed robot at the bottom of the page are missing the reinforcement parts. I will upload new pictures as soon as I modify it!
