Where Jules Verne Meets Star Wars: GE's Walking Truck
An anonymous reader writes "This July 4th weekend, millions of Americans will head to the air-conditioned confines of their local multiplex to take in Harry Potter, Captain America and other summer blockbusters. A military relic that foreshadowed a sci-fi vehicle featured in perhaps the most popular summer movie of all time – Star Wars – is on exhibit at the U.S. Army Transportation Musem at Fort Eustis: GE's Pedipulator, or 'Walking Truck,' developed for the U.S. Army in the mid-'60s. GE's quadroped was first imagined and lumbered through its testing paces in Pittsfield, Massachusetts, starting in 1962, 15 years before George Lucas's AT-AT walkers debuted on the big screen."
Turn in your nerd card subby. AT-ATs debuted in The Empire Strikes Back - 1980. That would be 18 years after 1962.
That's a well-known early development in walking machines. Technically it's closer to being an exoskeleton than a robot. It's slaved to the limbs of the guy inside, and is dependent on his balance reflexes. That didn't work out too well.
It took a long time to get legged machines to work well. Most early work was about gait and foot coordination. It turns out that balance is more important than gait, and slip control is more important than balance. It finally all came together with BigDog. (BigDog demonstrates that the technology was finally far enough along that throwing $20 million at the problem was a win. Money alone is not enough; see the Flight Telerobotic Servicer, on which NASA blew over $200 million in the late 1980s. DARPA also funded a 6-legged walking truck in the 1980s, but it never got beyond a slow walk on easy terrain.)
The GE walker dates from an era when American industry tried to push the state of the art with ambitious internal research projects. That's rare in the US today. But in Germany, there's Festo. Every year, Festo does an impressive robotics project. They've done a flexible manta ray which swims through water; it's highly maneuverable and moves and looks like a real manta ray. Most recently, they built a robot bird, which flies around gracefully and under good control.
Check out this robo-mule. It runs of a two-stroke engine and can withstand a kick to the side. The way in which it corrects itself in realtime is no different than that of a real animal. In fact, the motion is kinda creepy. A four legged headless beast.
