Robotic Soldier Suit

Iron Man watch out -- here comes Rex Jameson. Of course, "Iron Man" is Hollywood fantasy.

But Jameson is helping to develop what's called an "exoskeleton" suit that multiplies human strength and endurance up to 20 times.

He can easily lift a 200-pound weight -- 500 times in a row. Jameson works for Sarcos, a robotics firm in Salt Lake City.

The Army believes the robotic suit may someday help soldiers in combat.

But now the focus is on activities like loading cargo or repairing heavy equipment.

There are still significant issues to overcome, such as cost and power.

Current battery life is just 30 minutes -- hardly enough to make the suit practical.
