Patent ID: 8428776

Claim:
A method of defining an area of confinement for an autonomous robot comprising; a) positioning the autonomous robot at a starting point P 0 and recording the starting point P 0 as a reference point within a memory device of the autonomous robot; b) moving the autonomous robot from the starting point P 0 about a perimeter of the area of confinement in a desired direction, wherein said movement of the autonomous robot is controlled by a user; c) continuously tracking location of the autonomous robot relative to the reference point P o during said movement using a distance-traveled measuring mechanism and a directional indicating instrument: d) recording the tracked location of the autonomous robot as a map in the memory device; and e) upon detecting that the map includes a dosed-geometry, defining the closed-geometry as the perimeter of the area of confinement within the memory device; wherein the area of confinement, is defined without marking the perimeter of the area of confinement with a physical barrier.
