ABSTRACT:
According to the invention there is provided a floor treating machine having laterally spaced drive wheels driven by separate electric traction motors under electronic control so as to be driven by separate train of pulses, comprising means for recording the trains of pulses to the traction motors and means for replaying the record to reproduce the trains of pulses whereby the machine will repeat the operation. When replaying the record it is normally necessary to provide course correction by means of sensing devices for sensing the presence of a wall or other physical obstruction and further sensing devices for sensing the presence of unscrubbed floor, and means for providing overriding control by signals from the sensing devices.
