A cart may include: a driving wheel; a motor configured to rotate the driving wheel; a motor drive circuit configured to control electric power supply to the motor; a motor control device configured to control the motor via the motor drive circuit; a switching element arranged on an electric power supply path to the motor drive circuit; a switch circuit arranged separately from the motor control device and configured to switch the switching element between a conduction state and a non-conduction state; and an operation member arranged on the cart and configured to be operated by a user. The cart may operate in a manual mode in which the motor is driven when the operation member is on and the motor is stopped when the operation member is off, and in an automatic mode in which the motor is driven regardless of whether the operation member is on or off.

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 rotation speed sensor configured to detect a rotation speed of the motor; and a control device configured to control the motor via the motor drive circuit and the motor brake circuit based on a target rotation speed of the motor and the rotation speed detected by the rotation speed sensor. The motor brake circuit may include an electronically variable resistance element configured to operate in a linear mode and a switching mode in response to a control input signal. The motor brake circuit may be configured to operate. the electronically variable resistance element in the linear mode when braking the motor.

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.

A handcart includes a cart frame, a caster, and a code reader. The cart frame includes a receiving portion on which a shopping basket is placeable and a lateral portion extending in a width direction of the cart frame. The caster is disposed at a bottom region of the cart frame. The code reader is attached to the lateral portion of the cart frame so as to be rotatable around the lateral portion. The code reader may be rotated around the lateral portion of the cart frame to a first position at which a reading window of the code reader faces an inner space of the shopping basket on the receiving portion of the cart frame, and to a second position at which the reading window of the code reader faces a front of the cart frame.

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 walking aid vehicle (1) includes: an operation part (3) provided on an upper portion of a vehicle body for grasping by a user in a walking posture; a detector (30) for detecting an operation force applied to the operation part; and an inclination detector (20) for detecting inclination of the vehicle body. When an advance direction inclination detected by the detector is less than threshold, a normal control (100) generates a normal direction torque in the drive motor (40L, 40R) responsive to pushing the operation part (3) forward and generates a reverse direction torque in the drive motor responsive to pulling the operation part rearward, and when the advance direction inclination is equal to or greater than threshold and pushing operation force is detected, a shift to a pull control (110) is made which generates normal direction torque in the drive motor responsive to a pulling operation force.
