A ROBOT suit has been developed that could help older people or those with disabilities to walk or lift heavy objects.
Dubbed HAL, or hybrid assistive limb, the latest versions of the suit will be unveiled this June at the 2005 World Expo in Aichi, Japan, which opened last month. A commercial product is slated for release by the end of the year.
HAL is the result of 10 years' work by Yoshiyuki Sankai of the University of Tsukuba in Japan, and integrates mechanics, electronics, bionics and robotics in a new field known as cybernics. The most fully developed prototype, HAL 3, is a motor-driven metal "exoskeleton" that you strap onto your legs to power-assist leg movements. A backpack holds a computer with a wireless network connection, and the batteries are on a belt.
Two control systems interact to help the wearer stand, walk and climb stairs. A "bio-cybernic" system uses bioelectric sensors attached to the skin on the legs to monitor signals transmitted from the brain to the muscles. It can do this because when someone intends to stand or walk, the nerve signal to the muscles generates a detectable electric current on the skin's surface. These currents are picked up by the sensors and sent to the computer, which translates the nerve signals into signals of its own for controlling electric motors at the hips and knees of the exoskeleton. It takes a fraction of a second for the motors to respond accordingly, and in fact they respond fractionally faster to the original signal from the brain than the wearer's muscles do. The motors respond faster to signals from the wearer's brain than their own muscles
While the bio-cybernic system moves individual elements of the exoskeleton, a second system provides autonomous robotic control of the motors to coordinate these movements and make a task easier overall, helping someone to walk, for instance. The system activates itself automatically once the user starts to move. The first time they walk, its sensors record posture and pattern of motion, and this information is stored in an onboard database for later use. When the user walks again, sensors alert the computer, which recognises the movement and regenerates the stored pattern to provide power-assisted movement. The actions of both systems can be calibrated according to a particular user's needs, for instance to give extra assistance to a weaker limb.
The HAL 4 and HAL 5 prototypes, which will also be demonstrated at Expo 2005, don't just help a person to walk. They have an upper part to assist the arms, and will help a person lift up to 40 kilograms more than they can manage unaided. The new HALs will also eliminate the need for a backpack. Instead, the computer and wireless connection have been shrunk to fit in a pouch attached to the suit's belt. HAL 5 also has smaller motor housings, making the suit much less bulky around the hips and knees.
HAL 3 weighs 22 kilograms, but the help it gives the user is more than enough to compensate for this. "It's like riding on a robot, rather than wearing one," says Sankai. He adds that HAL 4 will weigh 17 kilograms, and he hopes HAL 5 may be lighter still.
Sankai has had many requests for the devices from people with brain and spinal injuries, so he is planning to extend the suit's applications to include medical rehabilitation. The first commercial suits are likely to cost between 1.5 and 2 million yen ($14,000 to $19,000).

Unavable for comment.
Coning very soon to a construction site near you!
I can see thousands of uses for something like this, likely followed by lots of workers comp claims, union protests and calls to outlaw it from Vincente Fox because now Americans can do jobs the Mexicans want.
With fifteen beers coursing through my viens, I can kick the ass of anybody on the planet.
I was thinking the same thing. That super strength might be handy to lift very heavy body armor. Be nice if someday our troops could laugh off an IED explosion.
Whenever I read a story like this, I like to fast-forward 30 years or so...
Yeah, yeah, yeah, this is great and all, for people who WANT to move around, but where is the beer helment and the diapers for NFL gameday?
"With fifteen beers coursing through my viens, I can kick the ass of anybody on the planet."
Quoted for Truth!!...LOL
Lol . . . I wonder if it'll be an offense to drive one of these bionic units under the influence?
heh heh
Nah, you just THINK you can kick ass. Then, the big sober guy you tried to throw a punch at.... but missed badly spinning around and falling to the floor.... is laughing so hard that he just feels sorry for you and decides to ignore you. You claim a drunken victory & celebrate by throwing up in your beer mug.
Either way, it's a victory!
Gentlemen, we can rebuild him. We can make him better than he was. Stronger, faster...

your 6 million dollar man needs to work on his stutter....lol..
Can you imagine the fun that hackers would have, in trying to wrest control away from the user? Imagine a demolition derby in a crowded area, not with automobiles but with robotic-assisted people!
In a related story, Hillary! requested a second waterproof black pantsuit, waste size LLL, be fabricated for her 2008 run.
