The human eye can rotate 500 degrees per second. Now a new robot eye is able to meet and exceed that ability by moving 2,500 degrees per second. German researchers led by Heinz Ulbrich at the Technical University of Munich developed this new head-mounted optical wonder:
The system, propped on a person's head, uses a custom made eye-tracker to monitor the person's eye movements. It then precisely reproduces those movements using a superfast actuator-driven mechanism with yaw, pitch, and roll rotation, like a human eyeball. When the real eye move, the robot eye follows suit.
