Panasonic spin-off ActiveLink is developing an exoskeleton that can assist a person in walking or running. The Powerloader light PLL-04, also called the Ninja, weighs 33 pounds and can assist a user at speeds up to 7.5 mph. It’s powered by a battery pack on the wearer’s back. The exoskeleton senses a user’s movements and moves in turn to ease the individual’s workload. The Ninja is still in development but will reportedly be on the market in three years. Here’s what it looks like in action:

Another version of the Powerloader is designed to help construction workers, farmers and anyone else who lifts heavy objects.
