Abstract: A cleaning roller mountable to a cleaning robot is featured. The cleaning roller includes an elongate member extending along a longitudinal axis of the cleaning roller, and a vane extending outward from the elongate member. The vane includes a first vane portion attached to the elongate member, and a second vane portion attached to the first vane portion. The first vane portion extends from the elongate member at a location intersecting a radial axis of the cleaning roller. The first vane portion extends along a first axis angled relative to the radial axis and away from the radial axis in a tangential direction. The second vane portion extends along a second axis angled relative to the first axis. A first angle between the first axis and the radial axis is greater than a second angle between the second axis and the radial axis.

Abstract: A mobile cleaning robot can be movable within an environment. The mobile cleaning robot can include a body, a cleaning head, a biasing element, and a linkage. The cleaning head can be operable to extract debris from a floor surface and can be configured to move vertically relative to the body between an extended position and a retracted position. The biasing element can be connected to the body and can be movable with the cleaning head. The linkage can be connected to the cleaning head and the biasing element. The linkage can be rotatably connected to the body to, together with the biasing element, bias the cleaning head toward the retracted position.

Abstract: An autonomous mobile cleaning robot can include a robot body, a bumper, and a coupling. The robot body can include a displacement sensor. The bumper can be moveably coupled to the body. The coupling can include a displacement limiter associated with the displacement sensor. The displacement limiter can inhibit or limit sensing by the displacement sensor of displacement of the bumper from the robot body caused by forces below a threshold horizontal force value.

Abstract: A cleaning bin mountable to an autonomous cleaning robot operable to receive debris from a floor surface includes a debris compartment to receive a first portion of debris separated from the airflow and a particulate compartment to receive a second portion of debris separated from the airflow. The cleaning bin also includes a debris separation cone having an inner conduit defining an upper opening and lower opening. The upper opening receives the airflow from the air channel. The inner conduit tapers from the upper opening to the lower opening such that the airflow forms a cyclone within the inner conduit.

Abstract: A robotic end effector includes a finger and at least one actuator. The finger extends from a proximal end to a distal end along a finger axis. The finger includes a first phalanx proximate the proximal end, a second phalanx proximate the distal end, and a knuckle joint including at least one vertebra interposed between and separating the first and second phalanxes. The knuckle joint is configured to permit the second phalanx to pivot relative to the first phalanx about a pivot axis transverse to the finger axis. Each vertebra has an axial thickness extending along the finger axis and a lateral width extending perpendicular to its axial thickness, and its lateral width is greater than its axial thickness. The at least one actuator is operable to move the second phalanx relative to the first phalanx about the pivot axis.

Abstract: A cleaning station for a mobile robot includes a fluid vessel and a roller arranged in the fluid vessel. The fluid vessel is shaped to hold a cleaning fluid that at least partially submerges the roller. The cleaning station includes a control system configured to, when the mobile robot is docked at the cleaning station, cause rotation of the roller to direct cleaning fluid from the fluid vessel to a cleaning pad of the mobile robot in order to release debris from the cleaning pad.
