The motor Driver Shield used in this project has current sense voltage output proportional to motor current. This feature has been used to protect DC motors against overload. In a tested case when the current per channel exceeded 9 A (4.5 A per motor) the motors power supply has been turned off. The following figures show the current consumption for the left and right channel during a test drive in rough terrain. The measurement data were recorded with a step of 200 ms.
