I suppose most advancements in the field of robotics come from Japan, and this High Speed Robot Hand is no exception. Ishikawa Oku from The University of Tokyo created this prototype, and it’s pretty amazing how far we’ve come in the last 10 years or so. At first, all we had were clumsy hands that could barely hold anything, and now, we have this robot hand that can probably take care of my iPhone better than I can.
The hand bounces balls, ties knots, and spins its chopsticks using high-speed actuators with harmonic drive gears. My main criticism of most humanoid robots is that they move too slowly, so I find this hand particularly fascinating.
