   General Electric was commissioned to design the cybernetic walking machine in 1966, and delivered it to the Army in August 1970.   Its four legs carried 500 pounds of cargo over extremely difficult terrain that was inaccessible to other vehicles.

   It stood 11 feet tall, walked 5 mph and was powerful enough to haul a jeep out of a mud hole.  It could also climb over large obstacles, balance on it's diagonal legs and push 1,000 pounds across a concrete floor.

Connected to numerous hydraulic hoses during testing, the walking machine could climb over obstacles.

   The operator, perched in the top of the walker, balanced and coordinated the legs through controls attached to his hands and feet.  

   Each hip had two swivel movements, and each knee could bend.   A feedback system allowed the operator to feel the load the walker was actually encountering, but at greatly reduced magnitude.

   It was surprisingly easy to operate.  With 2 hours practice, an operator could walk foward and backward, turn around and balance on two diagonal legs.

   In theory, it was a great tool, but it never made it out of testing.  It used 50 gallons of oil per minute, requiring it to be attached to hydraulic lines at all times.

   Army funding was soon cut, and the responsibility for moving heavy loads up uneven terrain was transferred to helicopters.
