Researchers around the world have focused on autonomous agriculture, with systems encompassing greenhouse, orchard, field and other applications. Research has shown the potential and ability of the technology to allow a vehicle or selection of vehicles to follow a specified task. In this study, one aspect of the problem, that of operating a tractor-cart combination in conjunction with a small-grain combine harvester, was investigated. The tractor-cart combination and combine harvester application was selected because of the high fatigue and long duration aspects of the problem. The system was simulated using two iRobot Magellan Pro robots in an indoor environment. The differential drive robots were software constrained to match the dynamics of typical agricultural vehicles. Position feedback was supplied by odometry. A small towed trailer was added to one robot to simulate a typical grain cart.
