Android, take a letter: Robotic hand helps people type

Virginia Tech researchers have designed a robotic hand that they hope to optimize for keyboard work, using 19 tiny servo motors to actuate their hand, all placed in a forearm and connected to the joints via wire tendons that ensure proper joint angles while typing.
In tests, one hand managed a top speed of 20 words per minute, but by adding a left hand, a typing speed of over 30 wpm is anticipated.
