Systems, apparatuses, and methods are provided herein for tracking shopping cart activity. A system for tracking shopping cart activity comprises a shopping cart system comprises a power generator configured to generate power with a rotation of a wheel system of the shopping cart, a power storage device configured to be charged by the power generator, and a system connector configured to couple with a computer system to provide energy information associated with the charging of the power storage, the computer system comprising: a shopping cart connector configured to couple with the system connection to receive the energy information from the shopping cart system, and a control circuit configured to estimate a distance traveled by the shopping cart system based on the energy information.

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 both rotation and in translation relative to the platform, for example by one or more electric motors housed in or on the platform or wheel clusters. Each of the wheel clusters comprises an arm, and a first and a second wheel rotatably mounted to respective opposite ends of the arm. Each of the wheels is independently powered about its respective axis of rotation. An electronic controller commands the motors to enable stable rolling movement of the device over a surface with only one wheel of each cluster in contact with the surface, and to allow the device to steer and to ascend and descend steps.

A power assist system for a wagon is provided. The power assist system provides a rotational force to one or more drive wheels under certain conditions to provide propulsion for the wagon. The power assist wagon preferably includes a drive system for providing the rotational force to the drive wheel, a control system for determining when the drive system should be activated and how much propulsion assist to provide to the drive wheel, and a power system for providing power to the drive system. The power assist wagon may also have a safety cut-off system to preclude the drive system from providing a rotational force to the drive wheel 16 even when the system is in the on mode.

A motorized vending cart includes a drive base, one or more drive motors mounted to the drive base and configured to rotate a plurality of wheels, a thermally insulated container mounted to the drive base, a power inverter mounted to the drive base, and a battery bank mounted to the drive base. The battery bank includes one or more batteries and is in electrical connection with the one or more drive motors and the power inverter. A vending cart body is mounted to the drive base and at least partially surrounds the thermally insulated container and the one or more drive motors. A control panel is electrically connected to and configured to control the one or more drive motors. An appliance is mounted to the vending section of the vending cart body and electrically connected to the power inverter.

A smart dolly includes a running mechanism and a body, the running mechanism comprises an equipment box and a rear axle housing, the equipment box is disposed on the rear axle housing, a battery, electric motor and control computer are provided in the equipment box, the battery and the electric motor are both electrically connected to the control computer, the equipment box has a charging plug thereon, the charging plug is electrically connected to the battery, the rear axle housing is provided with a differential clutch and an axle therein, the differential clutch and the axle form a transmission, the differential clutch is driven by the electric motor, the electric motor is provided with an electromagnetic braking device and a heat dissipation fan, and the external ends of the axle are connected to wheels; the body comprises an upper, middle and lower support rods.

A utility cart includes a cargo platform having a plurality of wheels, a plurality of electric motors coupled to the cargo platform, and a rideable platform configured to support a user. One of the plurality of electric motors corresponds to one of the plurality of wheels. Another one of the plurality of electric motors corresponds to another one of the plurality of wheels. The plurality of electric motors are configured to drive the plurality of wheels. The rideable platform is coupled to the cargo platform and includes at least one wheel. Additional example utility carts each including a cargo platform, a rideable platform and/or other optional features are also disclosed.

A tugger cart system used in an industrial setting, including a tugger cart and a controller. The tugger cart includes a tugger frame, a bay that is dimensioned to receive a rider cart, a platform configured to secure a rider cart within the bay, and at least one motor that pivots a plurality of wheels from side to side to steer the plurality of wheels. The tugger frame further includes a connector bracket that pivots from side to side along a vertical axis. The connector bracket is configured to attach the tugger frame to an adjacent tugger cart or tugger truck. A sensor system senses a degree that the connector bracket is pivoted relative to the tugger frame and generates an electronic signal. The controller receives the electronic signal from the sensor system and controls the motor to steer the plurality of wheels based on the electronic signal.

A motorized riding stroller is provided including a frame having a base platform, a handlebar, and a plurality of legs, wherein the plurality of legs extend from a lower surface of the base platform. The handlebar is pivotally affixed to a rear side of the base platform. An interchangeable seat is removably securable to an upper surface of the base platform. A standing platform is disposed between a pair of rear legs, wherein the pair of rear legs are disposed on opposing lateral sides of the base platform along a rear side thereof. A wheel is affixed to a distal end of each leg of the plurality of legs, wherein each wheel is operably connected to a motor disposed within an interior of the frame. The wheels rotate upon actuation of a drive control disposed on the handlebar, such that the stroller can move in opposing directions.
