Abstract
A transportation vehicle configured for riding and walking modes of use includes a support frame having a front end and a rear end; and a plurality of front wheels rotatably coupled to the front end, and a plurality of rear wheels rotatably coupled to the rear end. A seat is coupled to the frame and configured to support a driver. A steering assembly is operably coupled to the front wheels and configured to controllably pivot the front wheels for steering. A braking system is operably configured to stop motion of the vehicle. A rigid walking arm is pivotally coupled to the steering assembly at a pivotally mounted end of the walking arm. Motor operation and braking controls are provided on the walking arm for walking mode and adjacent to the seat for riding mode. A relay disables controls for one mode (e.g., walking mode or riding mode controls) while the other mode is effective. Switching logic for selecting between walking mode and riding mode is also provided. A motor controller receives input from controls, sensors and switches, and governs motor speed and direction in accordance with preset walking mode and riding mode control parameters.
