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 mobility device is provided and includes a base panel that supports a passenger. A plurality of wheels are disposed at a plurality of points of the base panel and are coupled to the base panel to be rotated with respect to a vertical axis. A rotary portion provides a rotational force to rotate the wheel with respect to the base panel. Additionally, a braking portion is disposed on the rotary portion to adjust the plurality of wheels to be rotated with respect to the base panel or positions of the plurality of wheels to be fixed.

Self-propelling trolley assembly (100), comprising a battery (156); at least one wheel (111,112) which is driven by an electric motor (151,152;1), which electric motor is powered by said battery; a rotation position or velocity sensor (9) arranged to sense a rotation position or rotation velocity of at least one trolley wheel (111,112); a user interface (153); and a control unit (150) arranged to regulate the electric motor based upon input from said user interface so as to affect a rotation of said wheel according to particular drive patterns. The invention is characterised in that the control unit is arranged to implement at least a feedback assisted propulsion drive pattern, based upon information read from said position or velocity sensor; a free-wheeling drive pattern; and a rocking drive pattern, in that all of said drive patterns are implemented using different drive voltage patterns to said electric motor, and in that the electric motor is of a type in which the stator (2) comprises a number of stator (2) poles (7) which is not an integer multiple of a corresponding number of rotor (3) poles and in which the stator poles are subdivided into at least three magnetically and electrically identical subsets (8) that are mounted one after the other around the angular direction of the electric motor.

A power assist system for a wagon having a safety cut-off system is provided. The power assist system preferably includes a wagon body having a plurality of wheels, at least one of which is a driven wheel, a pivotable handle, a drive system having a motor mechanically connected to the driven wheel, a microcontroller that obtains an input signal and provides an output signal to the drive system and, a safety cut-off system connected to the handle. In one embodiment the safety cut-off system includes a safety-control switch electrically connected to the microcontroller, and the microcontroller adjusts the signal sent to the drive system based on a state of the safety-control switch.

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.
