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.

A trolley includes: a vehicle body; omnidirectional wheels; drive units; a handle; a sensor; and a control device for controlling the drive units based on the longitudinal load, lateral load, and moment about the vertical axis applied to the handle detected by the sensor. The control device: sets a target longitudinal velocity of the vehicle body based on the longitudinal load, a target lateral velocity of the vehicle body based on the lateral load, and a target angular velocity about the vertical axis of the vehicle body based on the moment about the vertical axis; corrects the target lateral velocity based on the target angular velocity so that an absolute value of the target lateral velocity decreases as an absolute value of the target angular velocity increases; and controls the drive units based on the target longitudinal velocity, the corrected target lateral velocity, and the target angular velocity.

A truck includes a body, left and right wheels provided on the body, left and right drive units driving the wheels, a handle provided on the body, a sensor, and a control device. The sensor detects a front-rear load and a moment about a vertical axis applied to the handle. The control device sets a target front-rear velocity of the body based on the front-rear load, and sets a target angular velocity of the body about a vertical axis based on the moment about the vertical axis. In a case where a product of the target front-rear velocity and the target angular velocity is greater than a predetermined threshold, the control device performs correction processing on the target front-rear velocity so that the product is equal to or less than the threshold, and controls the drive units based on the corrected target front-rear velocity and the target angular velocity.

A battery-powered dolly in one aspect of the present disclosure includes a handle, a connector, a motor, a wheel, a detector, a rotation information acquirer and a controller. The controller stops supplying an electric power from a battery to the motor based on (i) a battery current value and/or a battery voltage value detected by the detector and (ii) a rotation information acquired by the rotation information acquirer.

A dolly for indoor and outdoor use including a supporting frame extending along a main axis of extension and a loading platform mounted above said frame. The dolly also includes at least one steering and drive wheel coupled to the bottom of the frame and at least one pair of idle wheels coupled to the bottom of the frame and positioned symmetrically relative to the main axis of extension. The dolly also comprises includes a control structure including a plurality of sensors configured for measuring a plurality of operating parameters of the dolly and for generating respective signals representing operating parameters and a processing unit configured to receive the representative signals and to impart a steering command to the at least one steering and drive wheel at least as a function of the representative signals.

Wheel assembly (200) a self-propelling trolley (100), comprising a wheel (111,112); an electric motor (151,152) arranged to perform a rocking drive pattern; an electric connector (220), arranged to connect the motor (151,152) to a battery (156); and a mechanical brake (230) activatable so that a rotational movement of the wheel (111,112) is limited, The invention is characterised in that the mechanical brake (230) is arranged so that, in an engaged state, the wheel (111,112) can turn freely in relation to the trolley (100) across a ground distance of between 5 and 20 cm between a first rotary limit position and a second rotary limit position. The movement limitation is provided by several elongated concentric tracks interacting with a pin.

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 drive wheels replacing the front wheels of the cart. The platform and system include motors, encoders, an IMU, a processor and a microcontroller. The system has a work environment mapping sensor and a cabled array of digital cameras, proximity or radar sessors, as well as weight sensors, lights, a 15 key control panel secured throughout the cart. When in autonomous mode, the system provides navigation, movement and location tracking with or without wireless connection to a server. Destination keys allow autonomous navigation to desired destinations. Looping, boomerang and home keys facilitate autonomous navigation for a variety working environments and situations. The radar sensors provide enhanced obstacle avoidance, cart localizing, route planning and human interaction capabilities.

An assisted thrust system for a carriage provided with wheels that includes a base to which a first directional wheel and a second directional wheel are fixed that are connected to the base so as to be able to rotate around a respective axis perpendicular to the base; to the base a first drive wheel and a second drive wheel are further fixed that are rotated by at least one gearmotor unit, which drives the first drive wheel by a first magnetic coupling device and the second drive wheel by a second magnetic coupling device.

Embodiments of the present disclosure are directed to a cart frame and modular, motorized cart. In some examples, the cart frame may comprise a wheel assembly, handles, and a kickstand. A modular article (e.g., litter, stretcher, game basket, etc.) may be attached to the top portion of the cart frame via at least one fastener (e.g., buttons, snaps, hooks, buckles, quick-detach mounts, etc.). The handles may be foldable and extendable. The kickstands may also be foldable and extendable. The handles, in some embodiments, may serve a dual purpose by folding to a certain length to function as a kickstand. In other examples, the cart may comprise an engine that may be gas-powered or electric. A battery may be affixed to the cart frame that powers the electric engine. Other objects may also be attached to the cart frame or modular article, such as a winch, tow bar, light, bumper, etc.

A hunting cart assembly includes a cart that includes a first frame which is pivotally coupled to a second frame such that the cart is positionable between a folded position for storage and an unfolded position for utilization. A pair of wheels is each rotatably disposed on the second frame to roll along a support surface. A pair of motors is each integrated into a respective one of the wheels. Each of the motors rotates the respective wheel in a first direction when the motors are turned on to urge the cart along the support surface. A lever is pivotally coupled to a respective one of the handles and the lever is in communication with the pair of motors. Each of the motors is turned on when the lever is urged into an actuating condition and each of the motors is turned off when the lever is biased into a de-actuating condition.
