The HAL suit was developed by Cyberdyne (not to be confused with Cyberdyne Systems, the company responsible for manufacturing Terminators). Despite the similar names, the suit is far from having Terminator-like features. Or Ironman for that matter. What is does have are some little blue circles that light up.
When a person attempts to move, nerve signals are sent from the brain to the muscles via motoneuron, moving the musculoskeletal system as a consequence. At this moment, very weak biosignals can be detected on the surface of the skin. HAL catches these signals through a sensor attached on the skin of the wearer. Based on the signals obtained, the power unit is controlled to move the joint unitedly with the wearer's muscle movement, enabling to support the wearer's daily activities.
The system was designed with physical rehabilitation and people with permanent disabilities in mind, but it will also be used for heavy labor at factories, rescue support at disaster sites, and the entertainment field. So it may be comparable to the system Raytheon is developing. But at least this one doesn't look like a heap of scrap metal. It looks like an iPod. And what do we know about iPods? That's right -- they don't work after your wife puts them through the wash. So, logically, neither will this suit.
One more picture of the thing in action after the jump.
Thanks Luke and Lee, now lets go dress up in cardboard armor and beat the shit out of each other with tree limbs in the front yard.
