You read that correctly. Apparently, batteries and motors aren’t cutting it. So researchers did what any self-respecting geek would do: they strapped rockets to it. Sorta.
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.
