Cyberdyne, a robotics company in Japan, has begun mass producing a exoskeleton suit. The first production run will be 400 units, but the company hopes to ramp this number up to a few thousand. The suit will be selling for somewhere around $4200 USD initially. At first, you can only buy the suit in Japan -- but a sales branch will be opening in the EU soon, and if that is successful, it seems likely that one will follow in the United States.
While "Cyberdyne" was the name of the fictional company that built Skynet and the Terminator in the film of the same name, the exoskeleton itself also uses a name made famous in science fiction films: HAL. The Hybrid Assistive Limb device increases human strength and can be used in a wide variety of jobs, such as heavy manual labor, emergency rescue situations, the entertainment field, and medical rehabilitation.
Science fiction seems to have had a tremendous influence on the brain behind the HAL robot, robotics researcher Sankai Yoshiyuki. In the video below, he claims an earlier influence from the grand-daddy of robotics in science fiction, Isaac Asimov.
