While Boston Dynamics’ Big Dog is pretty impressive, check out this video of the US Army’s first attempt at a quadruped vehicle. Created in the early 1960s with the help of GE, this Army experiment was the first successful attempt of replicating a four-legged animal with a mechanical machine.

This “Walking Truck” was driven by a single operator who moved each of the vehicle’s legs using force-feedback hydraulic levers. Choreographing the machine’s movement was quite complicated, and during testing the Army found that the operator needed a mental break after only 15 minutes of use. As you can see in the video, the vehicle flexes some serious muscle. It kicks a Jeep out of its way with little effort, but it is still able to gently step on a light bulb without breaking it, due to the level of tactile feedback received by the operator.

If it weren’t for government budget cuts, we could be living out [George Lucas’] dream of AT-AT based combat right this minute!

The Ripsaw MS1 is an unmanned ground vehicle built by two brothers in Maine. The tracked vehicle can go 0-60 in 3.5 seconds with an 80mph top speed. In its current form, it has a 2000 pound capacity, which opens the possibility for many different types of weapon systems. Control is provided by two people: one driver and one gunner. They work in independent remote stations. The Ripsaw could potentially be used in any application normally reserved for a tank. It could lead a charge without putting soldiers at risk.

We’ve been watching this project mature since 2005 when it was being marketed as a Grand Challenge competitor. This week it’s being demoed at the Army Science Conference. Check out footage of it in motion below.

British computer hacker [Gary McKinnon] lost his final appeal to block his extradition to the U.S. He stands accused of hacking into almost 100 U.S. military and NASA computers from his girlfriend’s aunt’s house in London over a four year period by the U.S. government. If convicted of the crimes in a U.S. court, he could face up to 70 years imprisonment. [Gary McKinnon] freely admitted to hacking into the computers, but claimed that he did it out of curiosity, not out of malice or any terroristic aims. He was looking for information on UFOs. The U.S. government claimed that in addition to hacking into the computers, he also stole 950 passwords and erased important files. [McKinnon's] next move will be to appeal to the European Court, and if unsuccessful, he will have no other option but to stand trial in the U.S. court system.
