Re: Mecanum wheels friction coeff- will it work?
hello all
have a question about mecanum drive system...
on a prototype we have, we are able to drive fwd,rev and srafe (sp?) sideways. however when we try to do a 360, or even 180 the robot jumps/jitters and barely rotates(<90deg.). im assuming this is because of a high frictional coef. between the carpet and the rubber wheels, but it just seems like a weird/cheapo wheel design(the 3 small rubber rollers as wheels)?
we are using the andy mark 8" mecanum. all rollers are pretty loose, and even. No random tight roller to bog us down.
any thoughts on this are greatly appreciated.
oh and this is on a level (actual) field carpet ~20'x20' area.
