This is about the closest thing to a Superman suit we've seen. Put it on, say its creators, and the motorized Hybrid Assistive Limb can "expand and improve physical capability" up to tenfold in activities such as walking, standing, and climbing stairs.
Through a sensor attached to the skin, "HAL" captures faint biosignals on the skin's surface that result from messages sent from the brain to muscles when a person attempts to move. A computer analyzes how much power the wearer intends to generate, then calculates the amount of torque needed to put limbs into action.
Especially noteworthy here is that the suit responds to intended motion, rather than actual motion.
"This is what we call a 'voluntary control system' that provides movement interpreting the wearer's intention from the biosignals in advance of the actual movement," explains Japan's Cyberdyne, which will soon begin manufacturing the cybernetic suits for about $4,200 apiece, possibly making it the first such wearable device aimed at civilians.
The company was formed by Sankai Yoshiyuki, a professor at the University of Tsukuba who is heading up research on HAL, which he says has the advantages of both robot and cyborg. Yoshiyuki says he was inspired by reading Isaac Asimov's "I Robot" as a child. … Read more
