A robotic system that includes a body, a hitch assembly coupled to the body, and a sensor array coupled to the body. The robotic system includes a processor and operating logic containing programming instructions thereon that, when executed, causes the processor to detect, via the sensor array, a location of a vehicle relative to the body. The programming instructions of the operating logic further cause the processor to detect, via the sensor array, a position of a hitch receiver along the vehicle and move the body toward the vehicle to position the hitch assembly proximate to the hitch receiver. The programming instructions of the operating logic further cause the processor to move the hitch assembly relative to the body and in alignment with the hitch receiver and engage the hitch assembly to the hitch receiver to securely couple the body to the vehicle.

A handle assembly for a cart with a power assist function can sense the direction that a user's force is applied, and provide assist power in the corresponding direction, such that the user can easily move the cart. A cart including the handle assembly allows the user to conveniently move the cart.

A personal mobility vehicle or scooter includes a least one swivel caster wheel supported at the rear of the scooter. The scooter has a body that includes a deck and a handlebar assembly. The scooter includes at least one front wheel with the deck extending between the at least one front wheel and the at least one swivel wheel. The scooter can also include an angled rear portion supporting a rear swivel caster wheel such that the pivot axis of the swivel wheel is inclined with respect to the top surface of the deck. Embodiments of the scooter also include a swivel braking assembly configured to apply a braking force to the at least one swivel wheel.

A mobility apparatus includes a frame, a body surrounding the frame having a front side, a rear side, a top side, a bottom side, and first and second lateral sides, a seat located on the top side of the body, a plurality of wheels attached to the frame, a motor for driving at least one of the plurality of wheels attached to the frame, a battery for supplying electricity to the motor, and a controller for directing movement of the mobility apparatus. The top side of the body includes seats for children to ride the mobility apparatus. The mobility apparatus may also include a tether cord or handrails for directing movement of the mobility apparatus, or the mobility apparatus may follow a transmitter or autonomously drive.

A track dolly to mount a camera and accessories thereon is provided. The track dolly includes a steering mechanism to enhance directional control of the dolly when in motion. The track dolly includes a plate, at least one rail coupled to the plate and designed to permit attachment of the camera or accessories thereto, a plurality of wheels rotatably mounted to the plate, a handle rotatably mounted to the plate, and a plurality of linkage members adjustably mounted to the bottom surface of the plate and operably connected to the handle. The linkage members are operably connected to any number of the plurality of wheels. The handle is maneuvered to permit the plurality of linkage members to rotatably adjust any number of the plurality of wheels relative to the plate, thereby adjusting the directional control of the dolly.

A cart that follows a transmission module based on position information of the transmission module and a method for moving the cart are provided. According to an embodiment of the present disclosure, the cart accumulatively stores the position information of the transmission module and generates a moving path based on the position information of the transmission module and moves.

An electronic pallet (e-pallet) includes a superstructure mounted to a wheeled base platform. A tether device defines an articulation angle with respect to a leading edge of the superstructure, and is grasped by an operator towing the e-pallet. A motor connected to driven road wheels transmits a drive torque to the road wheels responsive to motor control signals, including a desired yaw rate and ground speed. A speed sensor, angle sensor, and length sensor are respectively configured to determine an actual ground speed of the e-pallet, the articulation angle, and a length of the tether device. An electronic controller, in response to the input signals, generates the motor control signals using proportional-integral-derivative (PID) control logic. Coupled lateral and longitudinal dynamics control loops respectively determine the desired yaw rate and ground speed to accommodate for motion of the operator.

Robotic vehicle and use thereof for displacing a holder for goods, which is for instance loaded with goods, which vehicle can be operated in an empty position and a loaded position, comprising of (1) moving the robotic vehicle to a position under the holder in a first direction, wherein the robotic vehicle is in the empty position, wherein a holding means is countersunk in a body of the vehicle; (2) lifting the holder, wherein the robotic vehicle lifts the holder by performing a vertical movement of the holding means relative to the wheels of the vehicle, such that the holding means comes into contact with an underside of the holder, wherein the robotic vehicle transfers to the loaded position; (3) rotating driven wheels of the robotic vehicle from the first direction to the second direction without the body of the vehicle being rotated, and (4) displacing the robotic vehicle in the loaded position in a second direction, wherein the first and second direction enclose a mutual angle of between 60 and 120 degrees, preferably 75 and 105 degrees, more preferably 85 and 95 degrees, such as a substantially right angle.

The present invention relates to a removable electric propulsion system (1) intended to be coupled to a rolling object. Propulsion system (1) comprises a frame (2) provided with at least one wheel (3) driven by an electric machine, and at least one non-driven wheel (4), a handlebar (20) and means (5) for coupling the propulsion system to the rolling object, coupling means (5) comprising means for gripping and lifting at least one wheel of the rolling object. Handlebar (20) comprises a connection with frame (2) and/or driven wheel (3). Furthermore, the connection comprises a means (12) for locking/unlocking the handlebar relative to frame (2) and/or to a driven wheel (3) from a locking position where handlebar (20) is attached to frame (2) and/or to driven wheel (3), this locked position of handlebar (20) enabling electric propulsion system (1) to be moved by means of handlebar (20), to an unlocking position enabling at least free motion of handlebar (20) relative to frame (2) and/or driven wheel (3).
