Fighting in a war is not a pretty sight, and sometimes soldiers return with missing arms due to explosions and gangrenous wounds. Inventor Dean Kamen and his team managed to design an artificial arm at the behest of the Department of Defense which is capable of performing delicate actions such as picking up a pen and scratching one’s nose. Weighing a mere six pounds, this mechanical arm can be covered with a mirror-image cast of the other arm. Sound pretty much like Will Smith in I, Robot as he fends off a group of robots with his mechanical arm. Hopefully this invention will bring small miracles to the lives of disabled war veterans when released. Photo courtesy of Trnmag.
