  • We consider the problem of autonomous navigation in an unstructured outdoor environment. We describe the planning and control aspects of an implemented system that drives a robot at modest speeds (∼1 m/s) over a variety of outdoor terrain. In real time, we use a gradient technique to plan globally optimal paths on a cost map, then employ a predictive dynamic controller to compute local velocity commands. Our planner and controller are considered the “best in class” among 10 teams competing in… CONTINUE READING
