The self-propelled unicycle may include a suspension system configured to damp vertical movement of the board relative to the axle of the central wheel assembly when the vehicle encounters obstacles and bumps on the riding surface. Exemplary suspension systems include shock absorbers, rockers, push rods, bell cranks, and / or swing arms connecting the axle to the board. The suspension system may be located entirely below the foot deck of the vehicle.

A wheel (3) includes a core member (32) consisting of a tubular member (140) formed with a plurality of V-shaped notches (142) on one side thereof, and bent into an annular shape so as to close the notches, and a plurality of free rollers (60) each rotatably fitted on a linear section (120) of the tubular member located between a mutually adjoining pair of the V-shaped notches via a bearing (122) provided with an inner race (124) and an outer race (126), wherein a raised piece (130) is provided for each inner race on another side of the tubular member opposite from the one side as well as a protrusion (138) so as to engage an end surface of the inner race and fixedly secure the inner race to the core member.

An electric vehicle includes a first foot platform and a second foot platform rotatably connected to the first foot platform, each having a foot support surface. A wheel assembly positioned between the first and second foot platforms includes a wheel and a motor positioned within the wheel. A battery assembly supplies power to the electric vehicle. The electric vehicle is configured to transition between an unfolded state and a folded state. In the unfolded state, the foot support surfaces are oriented to be respectively stepped on by a user's first foot and second foot, and in the folded state the first and second foot platforms are closer to each other than in the unfolded state. When the electric vehicle is riderless and in the unfolded state on a horizontal ground, one of the first and second foot platforms is closer to the ground than the other to facilitate mounting.

A self-propelled, one-wheeled vehicle includes a suspension system configured to dampen up-and-down motion of a board relative to the axle of a central wheel assembly when the vehicle encounters obsta

A self-stabilizing, one-wheeled electric skateboard may include improved features. In some examples, the vehicle includes a status indicator viewable through a slot formed in an upper surface of the board. In some examples, the vehicle includes a convertible carrying handle transitionable between stowed and deployed positions. In some examples, the vehicle includes an interchangeable fender and fender substitute that may be removably coupled to an upper surface of the board. In some examples, a motor controller of the vehicle may operate a field-oriented control (FOC) scheme configured to control the electric motor by manipulating a direct current aligned with a rotating rotor flux angle and a quadrature current defined at ninety degrees from the rotating rotor flux angle. In some examples, the motor controller may be configured to permit intuitive dismounting of the vehicle by tilting and / or moving the vehicle backward.

The present invention relates to a self-balancing vehicle (1), the vehicle comprising a single wheel (4), a base (2) and a bearing (3), wherein the bearing is connected to the base and the base is connected one of the wheel or a central axle (CA). The vehicle is self-balancing due to properties of the base and bearing, wherein at least the bearing surrounds a section of the wheel, below the wheel's centre, thus allowing a wheel which is not enabled to balance, to balance due to the remaining features of the vehicle. The vehicle may further be adapted with robotic manipulators (RM), weapons (RM), batteries (BA), electric motors (EM), and a printed circuit board (PCB), the printed circuit board comprising wireless data transmission means, a processor or controller, the processor or controller adapted to receive or transmit instructions from the wireless transmission means and control the electric motors, weapons and robotic manipulators.

Disclosed is a method of throttling a vehicle that includes defining above an axis of rotation a tangent vector with a tangent direction that corresponds with an intended vehicle direction. Disclosed is a method of controlling a mobility device that includes receiving a first input that is indicative of a control of the mobility device, receiving a second input that is indicative of the control, defining a composite input based on the first input and the second input, and instructing a drive controller consistently with the composite input. Disclosed is a mobility device that includes a removable stalk that is configured for selectably connecting with a base that includes a ground-contacting member, a drive configured for driving the ground-contacting member, and a processor configured for responding to a signal from the stalk and correspondingly instructing the drive.

A system includes a tool and an emergency response vehicle transitionable between a motive gear and a non-motive gear. The emergency response vehicle includes a mount for removably securing the tool to the emergency response vehicle. The system further includes a scanner coupled to the emergency response vehicle and operable to detect the tool when the tool is secured to the emergency response vehicle by the mount and a controller communicatively coupled to the scanner. The system is configured to determine that the emergency response vehicle has transitioned between a non-motive gear and a motive gear and in response to determining that the emergency response vehicle has transitioned between the non-motive gear and the motive gear, cause the scanner to scan the emergency response vehicle for the tool to determine whether the tool is secured to the emergency response vehicle.
