The RobotLogic motor tester is a tool for prototyping robotics mechanisms. It is also useful for troubleshooting and isolating problems in robots. It can control two separate motors using three different control modes.

Modes of Operation
The motor tester has two independent outputs and supports 3 different modes. Just plug one or two motors into the output connectors and select your mode using the mode switch.

Mode 1: Up-down movement of the joystick commands the two motors to rotate in opposite directions. This is useful for testing arm mechanisms which have opposing motors.
Mode 2: X-Y mode, one motor is controlled by left-right movement of the joystick the other is controlled by up-down movement of the joystick.
Mode 3: Arcade mixing. Useful for testing drive-trains.

Here is a picture of our motor tester controlling a more complex mechanism which has motors that must move in unison in opposite directions:
