The WheelCommander™ controller takes the burden of complex feedback control firmware off of the main robot controller.

It provides powerful closed-loop control of two wheeled robots using simple RS-232 or I2C interface commands.

The WC-132 WheelCommander controller is a powerful yet tiny motion control module for use with the Nubotics WheelWatcherTM encoders. Unlike the many servo controllers on the market, the WC-132 uses the Nubotics WheelWatcher encoders to close the loop. It also provides general purpose digital I/O lines and analog inputs for interfacing with your sensors.

The WheelCommander controller takes the burden of complex feedback control firmware off of the main robot controller, and so provides powerful closed-loop control using simple RS-232 or I2C interface commands.

Further, the WC-132 can be given the dimensions of the robot platform – wheel diameter and wheel base – and so can accept velocity, rotation rate, position, and angle commands in real-world units, not arbitrary encoder clicks.

There are four digital I/O pins for general purpose use, as well as four analog I/O pins. Servo and logic supply voltages can be measured and compensated for.
