A mobile cleaning robot can include a body, a pad assembly, and a pad drive system. The pad assembly can be connected to the body and can be movable relative thereto. The pad drive system can be connected to the body and can be operable to move the pad assembly relative to the body between a stored position and a cleaning position.

Two in one mobile cleaning robot

A method includes operating an autonomous mobile robot (AMR) in a first physical location according to a first safety protocol of the AMR and based on a location of the AMR relative to a second physical location different from the first physical location and with a second safety protocol different from the first safety protocol, switching the AMR to operate under the second safety protocol rather than the first safety protocol while the AMR is located in the second physical location. The method also includes, in response to detecting that the AMR is exiting the second physical location after the AMR has completed operating in the second physical location, switching the AMR to operate under the first safety protocol.

Autonomous mobile robot using multiple safety protocols

A method of mowing with an autonomous robot lawnmower includes traversing a mowable area with the autonomous robot lawnmower carrying a cutter and a vegetation characteristic sensor. The vegetation characteristic sensor is configured to generate sensor data in response to detecting a vegetation characteristic of the mowable area. The vegetation characteristic is selected from the group consisting of a moisture content, a grass height, and a color. The method includes storing position-referenced data representing the vegetation characteristic detected across the mowable area. The position-referenced data is based at least in part on the sensor data and position data. The method includes sending data to a remote device to cause the remote device to display a map including information based on the position-referenced data.

Controlling robotic lawnmowers

A mobile cleaning robot can include a body, a drive wheel, and a wheel stop. The drive wheel can be connected to the body and can be operable to move the mobile cleaning robot about an environment. The wheel stop can be movable with respect to the body and the drive wheel between a stop position and a release position. The wheel stop can be engageable with the drive wheel in the stop position to limit vertical travel of the drive wheel with respect to the body.

Mobile cleaning robot with adjustable suspension

A method performed by a mobile lawn mowing robot includes pairing a beacon with the mobile lawn mowing robot. Pairing the beacon with the mobile lawn mowing robot includes determining a distance between the beacon and the mobile lawn mowing robot and confirming that the beacon is within a pairing distance from the mobile lawn mowing robot based on a comparison of the determined distance to a pairing distance. Pairing the beacon with the mobile robot lawn mowing robot further includes, subsequent to confirming that the beacon is within the pairing distance from the mobile lawn mowing robot, pairing the beacon with the mobile lawn mowing robot, and, following pairing, detecting wideband or ultra-wideband signals from the beacon, and using the wideband or ultra-wideband signals to enable navigation over an area.

Controlling robotic lawnmowers based on fluctuating weather conditions

A mobile robot includes a chassis, a shell moveably mounted on the chassis, and a cutting assembly mounted to the chassis. The mobile robot also includes a communication system that includes an antenna module disposed on a rear portion of the mobile robot. The antenna module includes a base assembly, and an antenna assembly mounted to the base assembly by a spring. The antenna assembly includes a ranging antenna, and at least three angle antennas arranged axisymmetrically about the ranging antenna, such that the ranging antenna and the three angle antennas define a tetrahedral geometry for determining an angle of arrival for one or more incident signals.

Ranging and angle of arrival antenna system for a mobile robot

A lightweight mobile robot includes a chassis less than 500 pounds and two independent tracked drives including a drive wheel assembly, four or more independently suspended bogie assemblies, an idler wheel assembly, a compliant front shoe fixedly coupled to an independently suspended bogie assembly positioned adjacent the idler wheel assembly, and a compliant elastomer track entraining the drive wheel, road wheels, idler wheel assembly and compliant front shoe. The bogie assembly includes a serpentine suspension arm having a corresponding road wheel rotatably mounted at a distal end thereof, the bogie arm swingable through a range entirely beneath the chassis. The serpentine suspension arm provides clearance for adjacent road wheels to swing past one another without making contact with any portion of the adjacent bogie assembly. The compliant elastomer track has center guides and peripheral drive features protruding therefrom for engaging the drive wheel, road wheels, and idler wheel.

High travel suspension for small ground mobile robots

A method for manipulating an object with a remote vehicle having a manipulator attached to a manipulator arm. The manipulator comprises a jamming or other phase change material in a housing. The method comprises pressing the manipulator housing to the object, activating the jamming or other phase change material to cause the manipulator to grasp the object, and moving one or more of the manipulator arm and the remote vehicle to manipulate the object.

Method and device for manipulating an object

A method and device for manipulating an object is provided. In an exemplary embodiment, a gripping device configured to grasp the object includes a housing, a jamming material inside the housing, a first actuator to actuate the jamming material, a first pressure activation device disposed on a first outer portion of the housing and configured to exert a constricting force on the first outer portion of the housing, and a second actuator to actuate the first pressure activation device. After the end effector is pressed against the object, the second actuator actuates the first pressure activation device to exert an inward force on the first outer portion of the housing and the first actuator actuates the jamming material to grasp the object.
