An automated guided trolley for transporting and/or handling a load. The trolley has a main frame for receiving the load and a supporting frame having two walking beams extending respectively towards the front and the rear of the trolley. The walking beams are mounted rotatably with respect to the main frame respectively about a first axis and a second axis and such a walking beam includes elements for securing one arm of one walking beam to one arm of the other walking beam and for supporting the first of these arms on the other arm.

An apparatus controller for prompting a rider to be positioned on a vehicle in such a manner as to reduce lateral instability due to lateral acceleration of the vehicle. The apparatus has an input for receiving specification from the rider of a desired direction of travel, and indicating means for reflecting to the rider a propitious instantaneous body orientation to enhance stability in the face of lateral acceleration. The indicating may include a handlebar that is pivotable with respect to the vehicle and that is driven in response to vehicle turning.

A method, system and apparatus for carrying a user including a board for supporting the user, a plurality of ground-contacting members coupled with the board, a motorized drive assembly coupled with the ground-contacting members and one or more sensors coupled with the drive assembly. In operation, the drive assembly adjusts the velocity of the ground-contacting member based on one or more distances of the board from a surface below the board as detected by the sensors.

A vehicle and a manufacturing method thereof is provided in which separation of positively charged airflow from a positively charged surface of a vehicle body can be prevented. A vehicle body is insulated from a road surface, and positive static charges accumulate on the vehicle body during propulsion. The vehicle comprises a self-discharge device that is adapted to decrease a positive potential of at least any one of specific points at which positively charged airflow flowing along a vehicle surface deviates therefrom, during propulsion of the vehicle, by discharging static electricity to produce negative ions according to the positive potential of the specific point.

An electric vehicle may comprise a board including deck portions each configured to receive a foot of a rider, and a wheel assembly disposed between the deck portions. A motor assembly may be mounted to the board and configured to propel the electric vehicle using the wheel assembly. At least one orientation sensor may be configured to measure orientation information of the board, and at least one pressure-sensing transducer may be configured to determine rider presence information. A motor controller may be configured to receive the orientation information and the rider presence information, and to cause the motor assembly to propel the electric vehicle based on the orientation and presence information.
