Walking Truck

The stepping of the robot was controlled by a human operator through foot and hand movements coupled to hydraulic valves.

The walking truck was one of the first technological hardware design applications to incorporate force feed-back to give the operator a feel of what was happening.

It was exhausting to control and, according to program lead Ralph Mosher who was the designer and primary driver, operators could only drive the walking truck for a limited time.

Plustech, a Finnish subsidiary of American agricultural, construction, and forestry machinery manufacturer John Deere, developed a "Timberjack Walking Machine"[4] or "Walking Tractor" meant to traverse forested terrain.

Locomotion is provided by six articulated legs, and it is capable of moving forward, backward, sideways, and diagonally.
