(PhysOrg.com) -- A new version of what some refer to as the "Iron Man" suit was unveiled Monday by Raytheon at the company's research facility in Salt Lake City.
While Robocop and Iron Man can dodge bullets and crush villains, a new powered suit from Japan promises its elderly users more modest powers, such as pulling up radishes without getting a backache.

Humans have evolved to be incredibly efficient at walking. In fact, simulations of human locomotion show that walking on level ground and at a steady speed should theoretically require no power input at all.

An exoskeleton is the external skeleton that supports and protects an animal's body, in contrast to the internal skeleton (endoskeleton) of, for example, a human. In popular usage, some of the larger kinds of exoskeletons are known as "shells". Examples of exoskeleton animals include insects such as grasshoppers and cockroaches, and crustaceans such as crabs and lobsters. The shells of the various groups of shelled mollusks, including those of snails, clams, tusk shells, chitons and nautilus, are also exoskeletons.
Mineralized exoskeletons first appeared in the fossil record about 550 million years ago, and their evolution is considered by some to have played a role in the subsequent Cambrian explosion of animals.[citation needed]
Some animals, such as the tortoise, have both an endoskeleton and an exoskeleton.
