Patent attributes
An electric vehicle includes a stem and a base with wheels. The base is at a first end of the stem, with symmetrical elements of the base opposed across a stem axis. Elements on each side include a wheel, a drive motor, a platform and pivot joints. The wheel has an axis of rotation. The drive motor is connected to the wheel. The platform is between the wheel and the stem. A first pivot joint connects the stem and the platform. A second pivot joint connects the platform and the wheel. In a first orientation, the platforms are substantially perpendicular to the stem and in a second orientation the platforms are substantially parallel to the stem. The wheel axes are substantially parallel to each other and are substantially perpendicular to the stem axis in the first orientation and the second orientation.
