A method and apparatus for positioning a manufacturing tool. A wheel assembly comprises a wheel plate and rollers. The wheel plate has a perimeter and an axis of rotation that is tiltable about a tilt axis. The rollers are arranged near the perimeter of the wheel plate, each of the rollers having an axis of rotation parallel to the tilt axis. An apparatus comprises an upper frame, a lower frame associated with the upper frame, a wedge slideably located between the upper frame and the lower frame, and a force applicator associated with the wedge.

Various embodiments herein relate to powered pusher devices configured to push wheeled objects from one location to another. Further embodiments relate to wheeled objects such as carts for transporting items from one location to another. Other embodiments relate to platform powered pushers that can be coupled to a family of various wheeled objects.

An automated carting assembly includes a cart that has a plurality of garbage containers each being positioned thereon. The cart has a slidably adjustable length for accommodation a varying number of the garbage containers. A pair of rear wheels is each rotatably coupled to the cart for rolling on a support surface and each of the front wheels is steerable on the cart. A pair of front wheels is each rotatably coupled to the cart for rolling along the support surface. A pair of steering actuators is each coupled to a respective one of the front wheels for steering the cart. A pair of drive motors is each rotatably coupled to a respective one of the front wheels for driving the cart between a storage point and a pickup point.

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 beverage keg dolly (BKD) system/method providing for transportation of a beverage keg (BK) in tight quarters is disclosed. The system/method integrates a dolly frame spine (DFS), axial wheel assembly (AWA), radial wheel assembly (RWA), keg alignment handle (KAH), keg engagement hook (KEH), beverage keg cradle (BKC), and vertical rotation handle (VRH). BK transportation uses the KAH to engage/cradle the KEH to a BK within the BKC. Once cradled by the BKC, the BK is lifted off the ground and supported by the AWA via depression of the VRH. The BK axially rotates about the AWA by the VRH until the BK center of gravity transitions a vertical equipoise plane (VEP) extending from the AWA. The weight of the BK is then supported by the AWA and the RWA. Transportation and/or circular rotation of the BK may then be affected by rotation/movement of the VRH.

A folding wagon allowing a user initiate a folding action by pressing or stepping down on a lever disposed on the front end, the rear end, or both ends of the folding wagon.

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 stall and tack cart for transporting livestock is provided. The livestock stall and tack cart generally incorporates telescoping members and stall carriers protruding vertically therefrom. The telescoping members allow for a length of the livestock stall and tack cart to be adjusted such that the stall carriers may hold one or more livestock stalls securely while the stall and tack cart is in motion. The devices and methods provided have the advantages of being as durable and capable of carrying heavy loads as currently existing livestock transportation solutions, but allow equipment for one or more livestock animals to be quickly and easily transported, for example, from a waiting or confinement area to an exhibition space, including through crowded, obstructed, or tight passages.

A portable surgical robot includes a surgical device and a cart. The surgical device is coupled to the cart. The cart includes a chassis, a mount coupled to the chassis, a carriage pivotally coupled to the mount, and a set of wheels. The carriage includes a first bracket positioned at a first lateral end of the carriage and a second bracket positioned at a second lateral end of the carriage. A first wheel of the set of wheels is coupled to the first bracket and a second wheel of the set of wheels is coupled to the second bracket. The carriage is configured to pivot relative to the mount to prevent at least one of (i) rocking of the portable surgical robot, (ii) fluttering of the first wheel, (iii) fluttering of the second wheel, and (iv) tipping of the portable surgical robot.

A method for controlling the an electric hand truck comprises the steps of: determining whether user manipulation is present due to a user input on the electric hand truck; and, if there is no user manipulation, then braking an electric motor that drives the wheels of the electric moving vehicle in a softlock manner in which, instead of power being applied to the electric motor, electrodes of the electric motor are short-circuited.
