Abstract
A machine for treating a surface area within a boundary perimeter includes a self propelled chassis having a surface treating device mounted on it. A computing section is mounted on the chassis and a powered wheel (or each of plural powered wheels) has a motor module for receiving command signals from the computing section. A position sensor is coupled to the computing section for generating a feedback signal representing the actual position of the machine. A data loading device coacts with the computing section for transmitting data to such computing section. A data file stores graphic data developed from a graphic depiction representing the surface area to be treated as well as other data developed in other ways. The data file coacts with the computing section and transmits graphic and other data to it. The computing section is arranged for processing the data and the feedback signal and responsively generating command signals directed to each motor module. Such modules, and the motors controlled thereby, propel the machine over the surface area selected to be treated. A method for treating a surface area is also disclosed.
