Abstract: Systems and methods for use of optical odometry sensor systems in a mobile robot. The optical odometry sensor system is positioned within a recessed structure on an underside of the mobile robot body and configured to output optical odometry data. The optical odometry sensor system includes an optical odometry camera that includes a telecentric lens configured to capture images of a tracking surface beneath the body and having a depth of field that provides a range of viewing distances at which a tracking surface is captured in focus from a first distance within the recessed structure to a second distance below the underside of the mobile robot body.

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.
