You might enjoy knowing that the suit featured in the video (link in post above) is being developed by a company named, none other than; 'Cyberdyne'. http://www.cyberdyne.jp/english/robotsuithal/index.html I've been following these people's research for a few years now and am very happy with their progress. They are likely to make some extremely beneficial progress of use especially to the medical community. However the control mechanism they are using is in fact 'not' very responsive in that it is not particularly accurate. While seven decades of additional research would certainly help., right now someone wearing this suit would find it quite impossible to play a gentle game of badminton. It's like an agility penalty of minus ten right now.
