Thai ground robot

shock absorber
https://www.youtube.com/watch?v=9Zvu0D0tkUI take this shock absorber idea and combine with below to make a rigid frame on the trackes, instead of having shocks on the rigid frame itself. combine with http://sasecurity.wikia.com/wiki/RoboTics#Robot_chassis, http://youshouldbuildit.blogspot.com/p/blueprints.html

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. One hack is to cut a used car tyre 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 hawkers.
