  • Patent number: 11194342
    Abstract: 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.

  • Patent number: 11084172
    Abstract: A robot obstacle detection system including a robot housing which navigates with respect to a surface and a sensor subsystem aimed at the surface for detecting the surface. The sensor subsystem includes an emitter which emits a signal having a field of emission and a photon detector having a field of view which intersects the field of emission at a region. The subsystem detects the presence of an object proximate the mobile robot and determines a value of a signal corresponding to the object. It compares the value to a predetermined value, moves the mobile robot in response to the comparison, and updates the predetermined value upon the occurrence of an event.

  • Publication number: 20210137003
    Abstract: An autonomous garden weeding robot includes a chassis, a motorized cutting subsystem, and a drive subsystem for maneuvering the chassis. A weed sensor subsystem is located on the chassis at a first elevation from the ground and a crop/obstacle sensor subsystem is located on the chassis at a second, higher elevation from the ground. The drive subsystem is controlled to maneuver the chassis about a garden. Upon detection of a weed, the motorized cutting subsystem is energized to cut the weed. The motorized cutting subsystem is de-energized after the chassis has moved a predetermined distance and/or after a predetermined period of time. Upon detection of a crop or obstacle, the drive subsystem is controlled to maneuver the chassis away from the obstacle.

  • Patent number: 10824165
    Abstract: A method of confining a robot in a work space includes providing a portable barrier signal transmitting device including a primary emitter emitting a confinement beam primarily along an axis defining a directed barrier. A mobile robot including a detector, a drive motor and a control unit controlling the drive motor is caused to avoid the directed barrier upon detection by the detector on the robot. The detector on the robot has an omnidirectional field of view parallel to the plane of movement of the robot. The detector receives confinement light beams substantially in a plane at the height of the field of view while blocking or rejecting confinement light beams substantially above or substantially below the plane at the height of the field of view.

  • Publication number: 20190054621
    Abstract: A weeding robot includes a chassis, a motorized cutting subsystem, a drive subsystem for maneuvering the chassis, a weed sensor subsystem on the chassis, and an acceleration sensing subsystem mounted to the chassis. The drive subsystem is controlled to maneuver the chassis about a garden by modulating the velocity of the chassis. Upon detection of a weed, the motorized cutting subsystem is energized to cut the weed. The acceleration of the chassis is determined based on an output of the acceleration sensing subsystem. The drive subsystem is controlled according to one or more preprogrammed behaviors if the determined acceleration of the chassis falls below a predetermined level.
