ABSTRACT:
A robotic vehicle including a chassis having front and rear ends, an electric power source supported by the chassis, and multiple drive assemblies supporting the chassis. Each drive assembly including a track trained about a corresponding drive wheel and a drive control module. The drive control module including a drive control housing, a drive motor carried by the drive control housing and operable to drive the track, and a drive motor controller in communication with the drive motor. The drive motor controller including a signal processor and an amplifier commutator in communication with the drive motor and the signal processor and is capable of delivering both amplified and reduced power to the drive motor from the power source. In one instance, the drive control module is separately and independently removable from a receptacle of the chassis as a complete unit.
