An active detection self-propelled artificial intelligence surgery navigation cart applied in medical institutes includes a cart body, a control unit, a signal transmission unit, a detection unit, a robotic arm and/or an optical navigation host. The cart can travel to a designated place or follow a counterpart (based on a stored map path) according to a predetermined schedule or an inputted instruction, or the cart can be controlled by an external remote control system or a counterpart to be followed, so as to achieve the effect of reducing the burden of medical staff while they are walking around, so that the medical staff can concentrate on the care of patients or improve the quality of surgical operations.

A sports training device for use on a ground surface includes motorized base mounted to a plurality of wheels connected with at least one motor, a power source, and a control circuit that includes at least one remote control receiver and is adapted to move the motorized base along the ground surface based on remote commands received by the remote control receiver. A support frame is mounted to the motorized base and holds height-adjustable vertical supports, and rotational and extendable lateral arms. A sporting dummy is fixed to a top end of each vertical support. A wireless remote control has a remote control circuit board, a power source, and a control interface, and is adapted to send the remote commands to the control circuit of the motorized base.

Some embodiments include a track system comprising: an elevated track system comprising a series of elevated tracks that are positioned elevated above a sales floor and products distributed over at least a portion of the sales floor of a retail store, and configured such that multiple motorized transport units travel along the series of elevated tracks in traversing at least portions of the retail store.

A device for transporting a payload (to include a human user) over varied terrain. A platform accommodates the payload. A pair of wheel clusters are mounted to opposite ends of the platform and are powered in rotation relative thereto. Each includes at least two co-planar wheels powered by electric motors. A latch is hand-operable (without tools) to secure the cluster to the platform and, alternatively, allow the cluster to be detached from the platform and rotated 90 to lie parallel thereto. An electrical connector conducts electric power from the platform to the cluster when the latch is operated/actuated to secure the cluster to the platform, and is configured such that it does not impede or obstruct detaching the wheel cluster from the platform, with no requirement that the user take any additional step (other than actuating the latch) to detach the wheel cluster.

Examples provides one or more rolling pallet trays capable of interlocking together to form a modular rolling platform. A rolling pallet tray includes a rectangular base member with a top surface, a bottom surface, and a set of four sides. The top surface may have a lip extending upward along at least a portion of the circumference of the top surface. A set of rollers are pivotally mounted to the bottom surface. A floor-lock brake may be activated to stop movement of at least one roller to lock the rolling pallet tray in place. A set of linking mechanisms is attached to one or more of the sides for linking the individual rolling pallet tray to one or more other rolling pallet trays in a variety of different configurations. The linked rolling pallet trays in the modular rolling pallet tray pivot together as a single unit for greater stability.

Some embodiments provide apparatuses and methods useful to providing control over movement of motorized transport units. In some embodiments, an apparatus providing control over movement of motorized transport units at a shopping facility comprises: a central computer system comprising: a transceiver; a control circuit; a memory coupled to the control circuit and storing computer instructions that when executed by the control circuit cause the control circuit to perform the steps of: obtain, from one or more of the communications received from the motorized transport unit, route condition information comprising information corresponding to an intended route of travel; obtain additional route condition information detected by one or more detectors external to the motorized transport unit; detect an object affecting the intended route of travel; identify an action to be taken by the motorized transport unit with respect to the detected object; and communicate one or more instructions.

An auxiliary transport vehicle according to the disclosure comprises a drive unit and an attachment that is placed thereon, wherein the drive unit comprises just two wheels with a common axis of rotation and each with an electric drive, an electronic control device and an electrical energy storage device, and wherein the control device is embodied for actuating the drives in such a way that the auxiliary transport vehicle is kept in an upright position, and for autonomously driving the auxiliary transport vehicle to a specifiable destination and for following an external control device. The disclosure also concerns an auxiliary transport system and a method for operating an auxiliary transport vehicle.

A smart luggage system includes a piece of luggage, a pull rod, at least one sensor, two driving wheels and two driven wheels. The luggage is configured to store items for transport. The pull rod is coupled to the luggage. The at least one sensor is coupled to the luggage and configured to detect a moving object. The two driving wheels and two driven wheels are coupled to the luggage, wherein the two driving wheels are motorized to move the luggage in a given direction. The pull rod and the at least one sensor are disposed on a front surface of the luggage. The two driven wheels are disposed near the front surface of the luggage and the two driving wheels are disposed near a rear surface of the luggage. The at least one sensor is configured to guide the luggage to follow the moving object.

A motorized device for transporting a human or inanimate payload. A platform is configured to accommodate the payload and a pair of wheel clusters are mounted to the platform at opposite ends thereof and are powered in rotation relative to the platform, for example by one or more electric motors housed in or on the platform or wheel clusters. Each of the two wheel clusters comprises three drive wheels arranged in a generally triangular and co-planar configuration, and each is independently powered about its respective axis of rotation by a hub-mounted electric motor. An electronic controller commands the motors powering the two wheel clusters and of each of the six drive wheels. The independent controllability of each wheel and of the wheel clusters relative to the platform allows the device to steer and to ascend and descend steps.

A motorized kayak cart is provided. The cart has a frame for supporting the hull of a kayak, a motor that drives two opposing wheels mounted on the frame, and stabilizing bars that contact a ground surface on which the cart rests and slides along the ground surface in order to maintain the cart in an upright position when the cart is in motion so that the cart does not tip over when in use.
