Abstract
In one embodiment of the present invention, an apparatus and method for establishing the perimeter of a work site for a mobile machine capable of operating autonomously or semi-autonomously includes activating a learning mode, positioning the mobile machine at a plurality of locations on the perimeter, and recording position data at each location from a sensor system, such as GPS, that provide signals corresponding to the position of the mobile machine. The position data is stored and a data processor associated with a control system generates a display of the perimeter so that an operator may visually verify the size, location, and shape of the work area bounded by the perimeter. Means to allow the operator to modify the entered position data is also provided.
