One Giant Step for Humanoids

An anonymous reader writes "There are a few robots that do amazing things. Honda's Asimo can walk backward and climb stairs. Sega's idog can dance to music. A tougher nut to crack has been making robots walk like humans. Today, scientists introduce three humanoid striders at the annual AAAS meeting. Unlike other robots that have to power every move, these three save energy by letting gravity do a lot of the work. Like humans, they pick up their feet and just let 'em drop. Engineers say they'll inform the next generations of humanoids and also improve design of robotic prostheses for people. And hey, why not send them to Mars to look for those microbes?"

Muscles, perhaps?

"...save energy by letting gravity do a lot of the work. Like humans, they pick up their feet and just let 'em drop."

That makes sense, but humans don't really just let their feet "drop." Our steps are actually quite controlled...if we just let gravity pull them down, we'd have pretty heavy footfalls, not to mention an awful lot of shuffling...

What an ignorant post. These are generic robotics problems that NEED to be solved if robotics are to evolve into what is today the realm of science fiction. The reason you keep seeing "yet another bi-pedal locomotion technique" is because scientists aren't satisfied with the current offerings.

Rest assured there are entire industries who make specialized robotics for the likes of the fast food industry, etc. What we need is more research into general robotic functions, such as walking, recognition, etc.
