There has been a similar research project at the UC Berkeley a few years ago.
"The Berkeley Lower Extremity Exoskeleton (BLEEX), as it's officially called, consists of mechanical metal leg braces that are connected rigidly to the user at the feet, and, in order to prevent abrasion, more compliantly elsewhere. The device includes a power unit and a backpack-like frame used to carry a large load."

I couldn't find any new information that was released after 2004. I wonder if they're still working on this.
Anyway, no thread about cybernetic exoskeletons is complete without a reference to "Aliens".

BITCH!"
