So you want something to look forward to in your fast approaching old age , eh? If robots playing baseball doesn't quite cut it, how's about a robohand that redefines what we understand by the word "dexterity"? The Ishikawa Komuro Laboratory is at it again , this time demonstrating robotic appendages with a reaction time of a single millisecond. Using harmonic drive gears and a (really) high-speed actuator, the three-fingered hands can tie your shoelaces, tweezer your brow, and even perform some kung fu pen spinning for the ladies. Video after the break -- skip ahead if you must, but don't miss out on the slow-mo action at 2:40 in the demo, it's pure kinetic poetry.[Via Hizook ; Thanks, Thomas B]
