The math you're suggesting may work for going straight forward or backward where slipping is limited. For a turn, it will not come close. Even getting the center of rotation of the turning robot will be difficult. The tracks will have to slip. A tracked robot can not turn without those tracks slipping. Differences in friction will alter the turn. More ...


A 360 degree turn takes: (width of robot/circumference of wheel) turns, neglecting track thickness, assuming the tracks are at sides if the robot. The length of track doesn't matter. Your robots non-slipping part of the track is traversing a circle of diameter=width of robot. The other parts of the track are sliding across the surface. A longer robot / ...
