Bionic Arm Powered by Rockets

‘Rockets can help power robotic arms, which could help lead to “better, stronger, faster” bionic limbs, research now reveals.

A new prototype rocket-powered mechanical arm can lift about 20 to 25 pounds—three to four times more than current commercial prosthetic arms—and can do so three to four times faster.

“Our design does not have superhuman strength or capability, but it is closer in terms of function and power to a human arm than any previous prosthetic device that is self-powered and weighs about the same as a natural arm,” said researcher Michael Goldfarb, a roboticist at Vanderbilt University in Nashville.

“It has about 10 times as much power as other [robotic] arms,” Goldfarb said.’
