  • Patent number: 9789384
    Abstract: A self-balancing board is provided, comprising a platform having a first foot deck portion to substantially support a first foot of a rider, and a second foot deck portion to substantially support a second foot of the rider. A wheel assembly is positioned between the first foot deck portion and the second foot deck portion along a longitudinal axis of the platform, and comprises a wheel having a rotation axis that is generally orthogonal to the longitudinal axis of the platform, and a motor unit driving the wheel. An orientation sensor senses the orientation of the platform. A controller receives data from the orientation sensor and controls the motor unit in response to the received data. At least one suspension interface between the platform and the wheel assembly has a single degree of freedom generally orthogonal to the rotation axis of the wheel and to the longitudinal axis of the platform, and biases the platform towards a rest position.
