Control Accessories

The Control Subsystem enables a human operator to maneuver the robot. Commands are issued through joysticks and buttons on the Transmitter, and sent via radio signal to the Receiver on the robot. In this way, the robot can be controlled through a combination of manual and autonomous methods.
