Dean Kamen was approached in 2006, by the US military, who stated that
at least 1,600 of the soldiers they sent overseas in the past few years
were missing at least an entire arm. All the army could do was give
them the same as they did during the civil war: A stick and a hook.
This really was the beginning of the modern arm prosthetics movement,
that has gained ground so quickly since then.
The military desired a prosthetic arm that was haptic, could pick up
a grape or a raisin without destroying it, and allow the amputee to
put it in their mouths - totally impossible to even imagine back then.
Over that next year, all of 2006, he built and lead a team to create
the first real prosthetic arm on the planet, the Luke Arm.
