Abstract: An autonomous golf cart is configured to automatically traverse a predefined cart path to a staging area near the green. The golf cart determines the green for the hole the golfers are playing and determines a final location proximate the green. The golf cart determines a route from the current location of the golf cart to the cart path, a route along the cart path, and a route from the cart path to the final location. The cart path is demarcated in various manners. The path markers may include unique visual features that can be captured by a camera on the golf cart for location determination. The golf cart generates a trajectory towards the next marker along the cart path and generates control actions to follow the trajectory.
