1. A machine for treating a surface area within a boundary perimeter and including:

  • a steerable self-propelled chassis having a surface treating device mounted thereon;

    a computing section mounted on the chassis;

    a plurality of powered wheels mounted on the chassis each having a motor module for receiving command signals from the computing section;

    a position sensor coupled to the computing section for generating a feedback signal representing the actual position of the machine;

    a data file storing graphic data developed from a graphic depiction representing the surface area to be treated;

    a data loading device for transferring graphic data from the data file to the computing section;

    the computing section processing the feedback signal and the graphic data and responsively generating command signals directed to the motor modules, thereby propelling the machine for steered travel over the surface area for treatment thereof.
