This is a promotional video for the HAL (Hybrid Assistive Limb) exoskeleton. This particular exoskeleton works by translating the movements of a person's muscles into movements of the machine. In the video they make the claim that a person wearing this robotic device can easily carry 5 times the weight that an unassisted person can carry.

Panasonic has developed a prototype exoskeleton that uses compressed air to help the wearer move limbs. The device is designed to help people with partial paralysis regain use of a bad limb. It functions by using sensors on the elbow and wrist that control eight compressed air 'muscles'. A picture is available at Cnet
