Abstract
A vehicle comprises a chassis, a mechanical system, and a control system configured to control the mechanical assembly. The mechanical system is mounted on the chassis and configured to be moved through a range of positions responsive to operator inputs from a human operator. The control system processing logic configured to generate output signals for the output devices based on input signals from the directional controller to thereby control movement of the boom assembly in accordance with the operator inputs. The communication system is configured to communicate signals, including the input signals and the output signals, between the directional controller, the processing logic, and the output devices, the communication system at least partially comprising a radio-frequency transmission medium.
