Description
The Core Motor Controller has two motor channels to connect 9 – 15 volt DC motors. Through the Motor Controller functions, you can control the speed and direction of each motor. Each motor channel port has an encoder for feedback.
The Core Motor Controller is powered by the Core Power Distribution Module using the supplied power cable and communicates with the Android device via USB.
The Motor Controller has three models for motor control and each channel can be independently controlled by the user program. The three modes of operation are:
- Run with Constant Power – Set the motor speed and direction.
- Run at Constant Speed – Set the desired motor speed and the controller will maintain that speed, even if there is a change of load on the motor.
- Run to Position – Set the desired encoder position and the controller will move the motor until the target position is reached and then it will maintain that motor position.

Motor channels can be set to reverse so that motors on the left and right side of the robot drive forwards when both given a positive power.
