robotics notes: the front wheel in the picture are two motorbike sprockets, center axial and back one. 6x2cm steel plates are welded to the motorbike chain. Then the tyre rubber is affixed to it with 5mm bolts. Cut a used car tire into 6x2 cubes.

Combine this with the irobot spiral plastic wheel which is actually a suspension. Build round sproket with rubber studs and coil spring for wheel. https://www.youtube.com/watch?v=peOlojYFK4Y 20secs. Thai robotics competition showcase
