Any help appreciated

.Are you talking about "crab" or "swerve" drive? There are drawings and info under those headings. And some teams that have people posting here can answer as to the complexity of the mech and programing. Most that I've seen have modules that swivel, truned with one chain per side. When looking at a swerve drive at Grand Valley, the team (sorry I forget their number) liked it but said it was a little over geared and tended to eat Fisher Price motors. I made a suggestion to put a spring loaded Z in the chain, on the outside of each "turning chain" and a piston or something on the inside so they could get the modules to form a O and do a tank style turn with out having to have the masses unballanced or be really geared down. I hope someday to be able to work with Students that have the machining (sp) skills to attempt a crab or swerve, for now I planning to stick with 4 wheel dirve and over power it to be able to turn.
