A roller is provided which has a roller body extending between a first roller end and a second roller end, the roller body defining a motor cartridge seat therein, and a motor cartridge having an elongated cartridge body extending along an axial direction between a first cartridge body end and a second cartridge body end, and a motor unit supported at the first cartridge body end. The motor cartridge is connected to the roller exclusively by the first cartridge body end leaving the cartridge body projecting in a cantilever manner. The motor unit transmits a rotation torque to the roller by shape coupling exclusively through the first cartridge body end.

A motor module has a bearing base, a stator, a rotor, a fixing base, and a circuit board. The bearing base, the stator, and the fixing base are sequentially and securely mounted to each other. The bearing base has a bearing base casing. The stator has a stator casing. The fixing base has a fixing base casing. Two end surfaces of the stator casing are respectively connected to an end surface of the bearing base casing and an end surface of the fixing base casing. The rotor is rotatably mounted in the stator, and is rotatably mounted through the bearing base. The circuit board is mounted in the fixing base and is electrically connected to the stator.

Features are disclosed for a stopping device that is resistant to forces in a first direction and compliant with forces in a second direction. The stopping device may be implemented in a roller top to restrict undesired horizontal movement of a payload being transported across the roller top. In some embodiments, the roller top can be implemented on a mobile robot to transport a payload between destinations. The stopping device can include a plurality of linkages to engage the stopping device and reduce forces applied to the stopping device by the payload. The stopping device, in an engaged position, may limit undesired horizontal movement of the payload. Further, the stopping device, in the engaged position, may respond to vertical forces applied to the stopping device by transitioning from the engaged position to a disengaged position.
