The previously announced abandonment of any mechanical and body powered type of prosthetic arms and hands by major manufacturers has now found new suppliers.
It appears that on the planet that real workers live on (not the chee chee froo froo world where carbon yacht fan Max Näder reams insurances with Michelangelo ""bionic"" hands) amputees drive innovation - not Centri, Hosmer, RSL Steeper, Touch Bionics or Otto Bock. They would have mechanical drafts they could most easily use to build useful nice looking body powered hands. It is just not what they do. So that is where us amputees come in.
Latest video of a Chinese farmer. Very impressive.
