ROBOT CONFINEMENT

摘要

An autonomous coverage robot system (5) includes an active boundary responder (600, 6012) comprising a wire (600, 6012) powered with a modulated current placed along a perimeter (1006A, 1006B) of a property (1001), at least one passive boundary responder (600, 600A, 600B, 600C, 600D, 600E, 600F, 600G, 600H, 600I, 6010A, 6010B, 6010C) placed on a property interior (1001A) circumscribed by the active boundary responder (600, 6012), and an autonomous coverage robot (10, 11, 12, 13, 14, 15, 16, 17, 18, 19). The robot (10, 11, 12, 13, 14, 15, 16, 17, 18, 19) includes drive system (400) carried by a body (100) and configured to maneuver the robot (10, 11, 12, 13, 14, 15, 16, 17, 18, 19) across the property interior (1001A). A signal emitter (1510) emits a signal, where the passive boundary responder (600, 600A, 600B, 600C, 600D, 600E, 600F, 600G, 600H, 600I, 6010A, 6010B, 6010C) responsive to the signal. A boundary responder detection system (1500, 1520) is carried by the body (100) and configured to detect both the active (600, 6012) and passive (600, 600A, 600B, 600C, 600D, 600E, 600F, 600G, 600H, 600I, 6010A, 6010B, 6010C) boundary responders. The drive system (400) is configured to redirect the robot (10, 11, 12, 13, 14, 15, 16, 17, 18, 19) both in response to the responder detection system (1500, 1520) detecting an active boundary responder (600, 6012) and in response to detecting a passive boundary responder (600, 600A, 600B, 600C, 600D, 600E, 600F, 600G, 600H, 600I, 6010A, 6010B, 6010C).
