As I have gotten older, I have noticed that recovering from manual work takes longer and longer as my poor muscles respond the unaccustomed labor. However, if researchers in Japan get their way, I can soon forget the aches and pains. This is pretty neat. It is basically a backpack with actuators that are powered with compressed air and controlled with a microcontroller. It gets superior performance compared to motor-based systems because of the power to weight advantages to compressed air. The whole apparatus weighs about 20 pounds.
This is a cool advance in personal-machine technology. I hope it does not lead to this though.
