Livestock and poultry industries play an important role in the food supply and economy of US agriculturalists. Current and historical trends show that the number of animals housed in individual facilities continues to grow on a yearly basis. While design improvements have enabled structures to physically house the growing number of livestock, a new problem exists in maintaining a safe indoor environment due to the increases in animal waste production. The Environmental Protection Agency is also beginning to enforce regulations to limit the daily emission rate of specific gases and odors associated with animal production. Research is needed to identify …

Biosystems and Agricultural Engineering Faculty Publications
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 …
