It expands from a ball, weighs half a pound, and lifts five pounds.
Depending on who you ask, DARPA is either the monster under our collective bed or they are the masked guardians of civil society. Sometimes both. Either way, they have a history of funding some pretty cool projects. This robotic arm is no exception. It was made by the company iRobot under contract by DARPA as a next-gen combat robot for use in environments too small or too hazardous for human soldiers.
The video after the jump is definitely worth watching. It weighs less than half a pound, inflates from a small ball, and can lift up to five pounds. It’s difficult to believe, but it works.
