Robot confinement
First Claim
1. A method performed by an autonomous robot lawnmower for cutting grass, the method comprising:
- following a path defined by one or more responders, an end of the path being in a second area, thereby crossing a first area between the second area and a third area, to move autonomously from the third area to the second area without cutting grass in the first area;
determining that the autonomous robot lawnmower has reached the end of the path and is inside of a perimeter of the second area based on detecting the one or more responders; and
cutting grass within the second area upon determining that the autonomous robot lawnmower is inside of the perimeter of the second area.

Abstract
An autonomous coverage robot system includes an active boundary responder comprising a wire powered with a modulated current placed along a perimeter of a property, at least one passive boundary responder placed on a property interior circumscribed by the active boundary responder, and an autonomous coverage robot. The robot includes a drive system carried by a body and configured to maneuver the robot across the property interior. The robot includes a signal emitter emitting a signal, where the passive boundary responder is responsive to the signal and a boundary responder detection system carried by the body. The boundary responder detector is configured to redirect the robot both in response to the responder detection system detecting an active boundary responder and in response to detecting a passive boundary responder.

10. A method performed by an autonomous robot lawnmower for cutting grass, the method comprising:
-
following one or more responders along a path, the path having an end in the a cuttable area, to cross a non-cuttable area, thereby autonomously moving from a second cuttable area to the first cuttable area while a grass cutter of the autonomous robot lawnmower is disabled; enabling the grass cutter when the autonomous robot lawnmower reaches the end of the path and is inside of a perimeter of the first cuttable area based on detecting the one or more responders; and
thencutting grass within the first cuttable area. - View Dependent Claims (11, 12, 13, 14, 15, 16)
