  • Patent number: 9218003
    Abstract: A system and method for mapping parameter data acquired by a robot mapping system is disclosed. Parameter data characterizing the environment is collected while the robot localizes itself within the environment using landmarks. Parameter data is recorded in a plurality of local grids, i.e., sub-maps associated with the robot position and orientation when the data was collected. The robot is configured to generate new grids or reuse existing grids depending on the robot's current pose, the pose associated with other grids, and the uncertainty of these relative pose estimates. The pose estimates associated with the grids are updated over time as the robot refines its estimates of the locations of landmarks from which determines its pose in the environment. Occupancy maps or other global parameter maps may be generated by rendering local grids into a comprehensive map indicating the parameter data in a global reference frame extending the dimensions of the environment.

  • Publication number: 20150355638
    Abstract: A method of operating a mobile robot includes driving the robot according to a drive command issued by a remote operator control unit in communication with the robot, determining a driven path from an origin, and after experiencing a loss of communications with the operator control unit, determining an orientation of the robot. The method further includes executing a self-righting maneuver when the robot is oriented upside down. The self-righting maneuver includes rotating an appendage of the robot from a stowed position alongside a main body of the robot downward and away from the main body, raising and supporting the main body on the appendage, and then further rotating the appendage to drive the upright main body past a vertical position, causing the robot to fall over and thereby invert the main body.

  • Patent number: 9149170
    Abstract: A method of navigating an autonomous coverage robot between bounded areas includes positioning a navigation beacon in a gateway between adjoining first and second bounded areas. The beacon configured to transmit a gateway marking emission across the gateway. In some example, the navigation beacon may also transmit a proximity emission laterally about the beacon, where the robot avoids cleaning the migration within the proximity emission. The method also includes placing the coverage robot within the first bounded area. The robot autonomously traverses the first bounded area in a cleaning mode and upon encountering the gateway marking emission in the gateway, the robot remains in the first bounded area, thereby avoiding the robot migration into the second area. Upon termination of the cleaning mode in the first area, the robot autonomously initiates a migration mode to move through the gateway, past the beacon, into the second bounded area.

  • Patent number: 9144361
    Abstract: A piezoelectric debris sensor and associated signal processor responsive to debris strikes enable an autonomous or non-autonomous cleaning device to detect the presence of debris and in response, to select a behavioral mode, operational condition or pattern of movement, such as spot coverage or the like. Multiple sensor channels (e.g., left and right) can be used to enable the detection or generation of differential left/right debris signals and thereby, enable an autonomous device to steer in the direction of debris.

  • Patent number: 9135554
    Abstract: A threshold learning control system for learning a controller of a robot. The system includes a threshold learning module, a regime classifier, and an exploratory controller, each receiving sensory inputs from a sensor system of the robot. The regime classifier determines a control regime based on the received sensor inputs and communicates the control regime to the threshold learning module. The exploratory controller also receives control parameters from the threshold learning module. A control arbiter receives commands from the exploratory controller and limits from the threshold learning module. The control arbiter issues modified commands based on the received limits to the robot controller.
