This kind of products is not really new, but we’ve not really saw it in action until now… The Robosuit made by some Students at Tokyo’s University of science will provide you enough assistance to carry heavy material.
If you go on their booth, they will let you try the “legs version”. The system is very simple… For example, if you have to carry heavy dumbbell put on the ground, you will have to bend over it as if you were going to carry the dumbell, and once you got it hands-on, and thanks to some sensors, the robosuit will pull you in order to straighten you up… Nice concept which we hope it will be available sometime in 2010…

Anyway, you should go on their booth to try it!
