A wheeled platform has a base, a plurality of wheels, and a power supply. A connector extends from the wheeled platform. A motor assembly has at least one motor mounted on the connector to couple with a stroller. A controller assembly steers the stroller. The base includes an upper surface for supporting an operator. The base forms a wheel assembly for holding the wheels. The power supply sends power to the motor assembly through the control assembly to drive the stroller.

An electrically driven moving vehicle includes a main body on which an article to be transported is loaded, and a handle provided on one side of the main body. A pair of force sensor units are provided in the handle. A force applied by a user is sensed by the pair of force sensor units to control the operation of electric motors. The user can operate the electrically driven moving vehicle while holding a position convenient for the user rather than a specific position of the handle. In addition, the user can conveniently operate the electrically driven moving vehicle with only one hand, without using both hands.

Methods, systems, and apparatus, including an apparatus that includes a motorized base configured to move the apparatus; an upper portion coupled to the motorized base; one or more load-sensing devices located between the motorized base and the upper portion, the one or more load-sensing devices being configured to (i) detect forces between the upper portion and the motorized base, and (ii) provide force information based on the detected forces between different portions of the upper portion and the motorized base; and one or more processors performs operations of: obtaining the force information provided by the one or more load-sensing devices; determining a difference between the forces indicated by the force information from the one or more load-sensing devices; determining, based the difference in the forces, a movement to be performed by the apparatus; and providing control information to cause the motorized base to perform the determined movement.

Known vehicles, e.g. used for the sport of golf, which are configured combined for riding along and to be pushed with motorized support, exclusively comprise a steerable, rigid frame, causing the vehicle when positioned on the side of a slope to tilt parallel to the slope plane, consequently resulting in a disadvantageous, safety-relevant tilting moment. For improved driving safety, it should be possible to tilt the vehicle sideways. The vehicle according to the invention can be used in at least two operating modes. In the ride-along mode, at least a second and/or third vehicle component can be moved by the operator or an automatic, thus causing the vehicle to tilt sideways. This enables a carving effect and the tilt compensation as well as a straight-ahead drive at least in side slopes and inclines. In the push mode, the male/female user walks behind or beside the vehicle, and at least two vehicle components and/or parts thereof are located in a position, relative to each other, different as compared to the position in the ride-along mode. The versatile embodiment variations make it possible to use it as a golf vehicle, as well as a recreational-/, shopping-/, transport-/, industrial-/, construction site vehicle, and as a vehicle for the transport of senior and handicapped persons, for exploration and military purposes, for mowing, as an agricultural vehicle, as gardening appliance and as a child carrier.

Apparatuses and systems that yield a zero torque steer for a pallet truck or similar vehicle are disclosed. In an embodiment, a motor is attached to a final drive. The final drive is equipped to a steer assembly such as a tiller that includes a drive wheel that is offset from the steering axis. The offset is determined on the basis of the drive wheel radius, divided by the ratio of the final drive. The ratio of the final drive is determined by selection of the sizes of a first and second gear. In embodiments, the first and second gears provide a right angle drive. The drive wheel creates a torque due to the offset that counteracts torque imposed by operation of the drive motor. Other embodiments may be described and/or claimed.

A robotic cart platform with a navigation and movement system that integrates into a conventional utility cart to provide both manual and autonomous modes of operation. The platform includes a drive unit with drive wheels replacing the front wheels of the cart. The drive unit has motors, encoders, a processor and a microcontroller. The system has a work environment mapping sensor and a cabled array of proximity and weight sensors, lights, control panel, battery and on/off, GO and emergency stop buttons secured throughout the cart. The encoders obtain drive shaft rotation data that the microcontroller periodically sends to the processor. When in autonomous mode, the system provides navigation, movement and location tracking with or without wireless connection to a server. Stored destinations are set using its location tracking to autonomously navigate the cart. When in manual mode, battery power is off, and back-up power is supplied to the encoders and microcontroller, which continue to obtain shaft rotation data. When in autonomous mode, the shaft rotation data obtained during manual mode is used to determine the present cart location.

The present disclosure is related to an electric pallet truck. The electric pallet truck includes a frame, a lifting unit, and a walking unit. The lifting unit is configured to adjust a height of the frame. The walking unit is configured to drive the frame to move. The lifting unit includes a lifting mechanism fixedly connected to the frame and a hydraulic mechanism configured to control a lifting of the lifting mechanism. The walking unit includes a driving mechanism configured at a bottom of the lifting mechanism.

The hoverboard buddy system utilizes a number of components that can be attached together with a hoverboard in a number of different configurations in order to expand the riding options of the user. In one embodiment, components include: a hoverboard, a saddle possibly with additional wheels and a stability bar, a plurality of straight handles, a plurality of curved handles, a plurality of accessory wheels, a split seat that independently actuates either foot pedal on a hoverboard, a fixed bench seat, pusher extension, and other components.

A basket assembly for receiving goods therein; a main body coupled to a bottom of the basket assembly to support the basket assembly; a handle assembly installed on one side of the main body; a wheel assembly rotatably coupled to a bottom of the main body to move the main body in a direction in which a force is applied to the handle assembly; and a battery installed inside the main body for supplying electrical energy to the wheel assembly.

This invention provides a rocking chair comprising a rear support frame arranged with a rotating part, a front rocking frame pivoted to the rear support frame and used as a front support frame, and an electric rocking drive mechanism driving the front rocking frame to continuously rock back and forth relative to the rear support frame; when the front rocking frame continuously rocks back and forth relative to the rear support frame, the distance between the moving part and the rotating part is alternatively decreased and increased to lift and lower pivoting point of the rear support frame and the front rocking frame relative to support surface. The rocking chair has automatic rocking and lifting function, and no additional fixing frame is necessary. The power requirement is low. When the moving part and the rotating part are wheels, the rocking chair can also be used as a stroller.
