A method is disclosed for controlling the movement of an autonomous, random movement electric machine within a zone of movement which may contain obstacles. The machine is fitted with at least two detectors fitted on either side of the machine centre line. The machine is operated in forward mode (phase a), its movement is reversed over a predetermined distance in response to an obstacle detection or zone boundary signal (phase b), its direction of movement is altered by turning it through a predetermined angle away from that of the detector emitting the signal (phase c), and its direction of movement is again reversed. An electric machine is also provided, particularly a lawn mower, using the above method. |
