Abstract
An elongated vehicle adapted to be propelled along an engaging surface and capable of climbing over obstacles on the engaging surface. The vehicle has a plurality of wheeled units including front and rear units with each unit having two axles and wheels mounted on the ends of the axles. Each unit, except for the front and rear units, shares its two axles with adjacent units. The front and rear units each share only one axle with an adjacent unit. Each unit has a body mounted on the axles and the body is rotatable relative to each of the axles. Each body includes side members to maintain the axles spaced apart longitudinally. The side members of the bodies of adjacent units intermesh and overlap at their shared axles to allow adjacent units to rotate vertically relative to each other. The side members include stop surfaces to limit rotation of adjacent units relative to one another about their shared axles. A drive mechanism is provided to drive the wheels.
