Robotic "Pack Mule" Offers Military Support

The modern warrior may need 100 pounds or more of gear—a load that can cause fatigue and impair performance. To lighten the load, DARPA is developing a pack-mule-like robot that would be integrated with a squad of Marines or Army soldiers.

The Legged Squad Support System (LS3) will be able to carry 400 pounds on a 20-mile hike without refueling. Sensing technology will enable the LS3 to hear, see, and respond to commands. And it will be nimble enough to follow the squad through rugged terrain and will serve as a mobile auxiliary power source.
