In an example implementation, a smart cart system may include a cart including a frame and an item holder supported by the frame and configured to transition between an open position and a storage position that is more compact than the open position. The smart cart system may include a motivator configured to provide a motive force to the cart, a power source coupled with the motivator, and a charging interface attached to the frame of the cart and that interacts with a cart charging system of a cart storage rack to charge the power source. The smart cart system may also include a user interface device, a computing device, and a smart cart controller operable on the computing device to receive information describing an attribute of an item and provide information describing the attribute of the item for presentation by the user interface device.

A stroller frame, comprising at least one motor, particularly an electric motor, for assisted driving of the stroller frame, a pusher bar for pushing the stroller frame and at least one force sensor device for detecting a direction and/or an amount of force and/or a force component acting on the pusher bar, and/or for detecting a value derived from said force or force component, particularly a temporal change of the force or force component.

A load handling system for a vehicle includes a set of forks that concurrently supports two or more pallets including a first pallet and a second pallet linearly positioned along a length of the forks, and a lifting system to raise and lower the forks. A traction system moves the vehicle in a direction of travel associated with withdrawing the forks from the pallets. Additionally, an actuation device generates an activation signal in response to being actuated by an operator, and a vehicle controller places the vehicle in an automated mode of operation in response to receiving the activation signal. In the automated mode of operation, a front end of the forks moves from the second pallet to the first pallet, and the first pallet is raised while the second pallet remains on a transport surface. The first pallet is then spaced apart from the second pallet by a predetermined distance and then lowered to the transport surface.

A system for a pallet truck load wheel mechanism comprises a logic device and first and second sensor arrangements. The first and second sensor arrangements include first and second sensing fields that define first and second edges of an operability window, respectively. The logic device has an operable state indicating that the load wheel mechanism can raise a pallet lifting device and an inoperable state indicating that the load wheel mechanism should not raise the pallet lifting device. The logic device is initialized in the operable state and is configured to change to the inoperable state in response to each time the first sensor arrangement detects an edge of a board intersecting, the first edge of the operability window and to change to the operable state in response to each time the second sensor arrangement detects an edge of a board intersecting the second edge of the operability window.

A cart may include a driving wheel, a motor configured to rotate the driving wheel, a motor drive circuit configured to drive the motor, a motor brake circuit configured to electrically brake the motor, a control device configured to control the motor via the motor drive circuit and the motor brake circuit so that a travelling speed of the cart becomes equal to or lower than an upper limit travelling speed, and a temperature sensor configured to detect a temperature of the motor brake circuit. The control device may be configured to change the upper limit travelling speed to a second upper limit travelling speed lower than the first upper limit travelling speed when the upper limit travelling speed is a first upper limit travelling speed and the temperature detected by the temperature sensor exceeds a first predetermined temperature.

A self-propelled goods stair climber includes: first and second motorized tracks and an elongated configuration parallel to a straight forward travel direction; a loading surface implemented to tilt with respect to the tracks around a first transverse axis perpendicular to the tracks; an actuated stabilization member movable between an extracted position so that the weight of the stair climber is carried at least in part by the stabilization member and a retracted position in which the stabilization member is not loaded; a proximity or support sensor carried by the stabilization member to send a signal of approach or contact with a floor; an electronic control unit programmed to activate the first and second tracks on the basis of said signal when the stabilization member is extracted; and check an inclination of the loading surface to be maintained in a predefined angular range with respect to a horizontal direction.

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.

To be self-propelled in a simple configuration and to perform manual operation smoothly and briskly. A driving wheel includes: a base portion; a rotating shaft (first shaft) rotatably provided with respect to the base portion; a rotation member rotatably provided around the rotating shaft; a drive shaft (second shaft) provided on the rotation member orthogonally to the rotating shaft; a drive wheel provided on the rotation member and rotatable around the drive shaft; a drive unit provided on the rotation member and configured to rotationally drive the drive wheel; and a lock mechanism configured to permit rotation of the rotation member with respect to the base portion, and meanwhile, to deter the rotation of the rotation member with respect to the base portion.

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.
