When one wheel is commanded faster than the other, the yoke pivots up to about 30 degrees in the direction of the turn, and pulls the rest of the chassis around in a smooth turn without having to slow down.
Do you have any difficulties tracking straight? For example, lets say your right wheel is faster than the left one. If you slow the right wheel down so it's the same speed as the left one, won't you continue your arc? Or do you have code to bring your "red wagon drive" back into a alignment?
