Re: Front wheel steering VS. 4WD

its a small field with 6 robots buzzin around on it.. the steering better have a heck of a turning radius.. also for the steering, im assuming you are thinking about how a car turns, more or less.. hope you have a heck of an idea on how to do that easily and efficiently at ALL speeds.. its not as easy as it looks.. with 4wd, if you tension the chains correctly, and align the wheels and sprockets right, the chain will never break.. the problem with 4wd is the differential in turning.. the outside wheel needs to go faster than the inside wheel.. find someone with a 4wd truck and ask them to go drive it in tight circles in a dry parking lot in 4wd..its not pretty.. a robot will not have the drastic effects that the truck did, but you better make sure that it is well built and aligned properly.. unless you have a proven method for the front wheel steering, I would go with the proven 4wd.
