An electric vehicle may comprise a board including first and second deck portions each configured to receive a left or right foot of a ride, a wheel assembly disposed between the deck portions and including a ground-contacting element, a motor assembly mounted to the board and configured to rotate the ground-contacting element around an axle to propel the electric vehicle, at least one sensor configured to measure orientation information of the board, and a motor controller configured to receive orientation information measured by the sensor and to cause the motor assembly to propel the electric vehicle based on the orientation information. The electric vehicle may include exactly one ground-contacting element, and the motor may be a hub motor.

A robotic omniwheel system for motion comprising various components such as in wheel motor assemblies with brake, supportive hub and axle assemblies, strut and yoke assemblies for suspension, a motor device having controller for steering motion, a motorized universal joint for rocking motion, an active transmission rod to uniquely engage lift and expansion which are managed by a drive logic system comprising status control system and sensor array, laser radar, GPS, and as well as manual navigational control system including wireless remote control for communication and monitoring motion states for transport and to monitor power levels therein. As well, an electrical system includes battery array to furnish power for the robotic omniwheel array assemblies and to the electrical components via power cable. Accordingly, a navigational system can control components by a cell phone device and by a remote controller device with toggle switches, and also by a remote control panel having touch screen monitor and thusly allowing the robotic omniwheel array to move about in a holonomic manner for transport.

A self-propelled, one-wheeled vehicle may include a board having two deck portions each having a concave front footpad configured to receive a foot of a rider, and a wheel assembly disposed between the deck portions. The concave front footpad has a rider detection sensor in the form of a membrane switch conforming to the shape of the footpad (e.g., facilitated by one or more slots formed in the membrane switch). A motor assembly drives the vehicle in response to board orientation and rider detection information. The vehicle may have a secondary battery chargeable via a three-pin charging port including an input pin, a ground pin, and an identification pin configured to receive an expected identification signal from an external charging circuit.

A powered unicycle device, comprising: a single wheel; a motor adapted to drive the wheel; a balance control system adapted to maintain fore-aft balance of the unicycle device by controlling the motor; at least one foot platform for supporting a user of the unicycle device; and a casing comprising at least two casing portions adapted to be movable between a closed configuration, in which the outer rim of the wheel is substantially covered, and an open configuration, in which at least a portion of the outer rim of the wheel is exposed for contacting a ground surface.

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.

A method and system for controlling an electric mobility are provided. The method and system may determine whether a brake is operated in a stationary state in which the electric mobility is stopped; convert the state of the electric mobility from the stationary state into a brake operation state if it is determined that the brake is operated in the stationary state; determine whether the brake is released in the brake operation state; and convert the state of the electric mobility from the brake operation state into a standby state in which the mobility can be started if it is determined that the brake is released in the brake operation state.
