1. An autonomous mobile apparatus for performing work within a pre-defined area, the apparatus comprising:
- a platform (28);
two ground engaging drive wheels (2) positioned one at each side of said platform (28);
drive means (11, 12) for independently driving each said drive wheel;
a control device (14) for continuously controlling said drive means (11, 12), whereby operation of said drive means (11, 12) causes the apparatus to progress over a predetermined route within said predetermined area; and
at least one border sensor (6) coupled to said control device (14) for sensing the proximity of signal means (23, 24) defining the borders of said predefined area, characterised by a navigation device (13) coupled to said control device (14) for sensing the orientation of the apparatus, said navigation device comprising a digital compass.
