New robotic arm powered by rockets

New robotic arm powered by rockets
Artificial limb is stronger and faster than commercial ones

The new rocket-powered robotic arm, shown in this diagram, is stronger and faster than the ones on the market. Here's how it works: The propellant cartridge contains pressurized liquid hydrogen peroxide, which is routed through two flexible lines (not shown) across the elbow joint and into two catalyst packs. The catalyst burns the hydrogen peroxide, generating steam that pushes pistons up and down — allowing the arm to move.

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.

'Talking to the guys who have been through it'
Peer visitor program helps military amputees adjust

The doctor's message pierced the fog of ache that had set in after a bomb exploded under Lance Cpl. Robert McCardle's truck four months ago in Iraq.

Marine Lance Cpl. Robert McCardle (left) and Army Spc. Joshua Hooker have benefited from a local project sponsored by the Amputee Coalition of America and the Wounded Warrior Project.An infection was slowly killing muscle around the wound in his lower right leg. The physician said McCardle, 21, could keep his useless leg and face constant pain or amputate it below the knee and start a new life.

Sorry for the Time Away

I have not posted in several months. I will begin again and backpost articles as time allows. I hope some of you find this compilation of articles helpful.
