The goal of this project was to evaluate the potential of a controller area network (CAN bus) to be used as the communication network for a distributed control system on an autonomous agricultural vehicle. The prototype system utilized microcontroller-driven nodes to act as control points along a CAN bus. Messages were transferred to the steering, transmission, and hitch control nodes via a task computer. The task computer utilized global positioning system data to generate appropriate control commands. Laboratory and field testing demonstrated that each of the control nodes could function simultaneously over the CAN bus. Results showed that the task ...

The development of a diverse, modular and portable system to accurately measure and record field operations is required to effectively bring identity preservation of crops to all farms and farmers. A demonstration system has been built based on a worldwide standard communications protocol and was evaluated for its ability to efficiently measure a variety of field operations and management practices. The CAN Bus 2.0B communication protocol was used to record GPS location data, ground speed and simulated spraying system data. This data was compiled and stored in a form that was compatible with multiple software programs for the purposes ...
