Because in a rolling motion between to semi rigid surfaces the friction is negligible. So if we consider the friction at the start up static friction rises to its maximum without any movement of robot till it jerks to move, then it will drop to near zero, while the speed of robot is the same as that of the wheels. Now if you push more power to start slippage the force is not going to increase no matter how fast the wheels turn. | |
