Patent number: 11194342Abstract: A robot lawnmower includes a body and a drive system carried by the body and configured to maneuver the robot across a lawn. The robot also includes a grass cutter and a swath edge detector, both carried by the body. The swath edge detector is configured to detect a swath edge between cut and uncut grass while the drive system maneuvers the robot across the lawn while following a detected swath edge. The swath edge detector includes a calibrator that monitors uncut grass for calibration of the swath edge detector. In some examples, the calibrator comprises a second swath edge detector.Type: GrantFiled: July 27, 2018Date of Patent: December 7, 2021Assignee: iRobot CorporationInventors: Paul E. Sandin, Joseph L.
