  • Systems and methods for use of optical odometry sensors in a mobile robot
    Patent number: 9744670
    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.
