An easier method for the calibration of differential drive robots is presented. Most calibration is done on-board and it is not\nnecessary to spend too much time taking note of the robotâ??s position. The calibration method does not need a large free space\nto perform the tests. The bigger space is merely in a straight line, which is easy to find.The results with the method presented are\ncompared with those from UMB for reference, and they show very little deviation while the proposed calibration is much simpler.
