摘要： A roller assembly for a mobile cleaning system for cleaning a work surface can include a drive shaft, a sheath, a bushing, and a bushing shroud. The drive shaft can be rotatable about a drive axis, and the drive shaft can include a driven end and an opposite bushing end. The sheath can be supported by the drive shaft and the sheath can be rotatable with the drive shaft. The sheath can include a shell engageable with the work surface. The bushing can be located about the bushing end of the drive shaft. The bushing shroud can be connected to the bushing. The sheath and the drive shaft can be together rotatable with respect to the bushing and the bushing shroud, the bushing shroud can include an outer portion defining a first radius of curvature and a recessed portion connected to the outer portion.

摘要： A protractible and retractable mast system for an autonomous mobile robot includes an elongate flexible member including a first lateral end and a second lateral end, and a fastener having a first portion extending along a length of the first lateral end and a second portion extending along a length of the second lateral end. The flexible member is configured to be at least partially coiled within a body of the robot, and a portion of the flexible member is vertically movable away from the body when the flexible member is being uncoiled. The fastener is configured to connect the first lateral end to the second lateral end when the flexible member is being uncoiled, and disconnect the first lateral end from the second lateral end when the flexible member is being coiled.

摘要： An autonomous mobile robot includes a flexible member including a polymer layer extending along an entire length of the flexible member, and an end portion vertically movable away from a body of the robot. A first portion of a fastening mechanism extends along a first lateral edge of the polymer layer and a second portion of the fastening mechanism extends along a second lateral edge of the polymer layer. The first portion of the fastening mechanism is attached to the second portion of the fastening mechanism and forms a conduit to support the image capture device. The conduit includes an inner surface and an outer surface, and the outer surface of the conduit is at least partially defined by the polymer layer. An image capture device is mounted to an end portion of the flexible member.
