gloomyandy wrote:Using a compas to reduce errors can be pretty tricky. Although in theory a compass should help with this sort of thing, I've yet to see a robot that has used one to give better results than what can be obtained by a carefully calibrated one using the standard differential pilot. One of the problems is that the data from the compass is very noisy and things like metal objects and the robots own motors tend to throw it off. I'm not saying it can't be done, just that it may be harder than you think!
