Each Servomotor is slightly different and this is why we need to calibrate them.
After successfully calibrating both motors, the SumoRobot will drive more straight.

Search for the maximum and minimum speed of each motor in both direction.
For the maximum speed, try to find where the motor does not go anymore faster.
For the minimum speed, try to find where the motor still slightly moves.
NB: The numbers do not represent the speed, it's an internal calibration parameter.
