Personal pneumatically-powered or power-assisted light wheeled and tracked vehicles are provided. In some embodiments, the vehicle includes drive wheels propelled by a reciprocating pneumatic prime mover fastened to the structure of the vehicle. In some embodiments, every drive wheel is propelled by a different single pneumatic prime mover operative to turn the driving wheel through a crank arm, one-way clutch or any other arrangement, converting the prime mover reciprocating motion to rotation motion, directly or indirectly through a supplementary drive device or/and transaxle comprising steering device. The disclosed vehicle includes a control mechanism for controlling the velocity or the velocity and direction of the vehicle. In some embodiments, the disclosed vehicle is a skid steer vehicle, and steering is provided by controlling the relative rotational velocity of drive wheels. Exemplary reciprocating prime movers include but are not limited to pneumatic cylinders, rotary actuators, fluidic muscles, and pneumatic bellows. |
