Speedy robo-cam mimics the movements of the human eye, exceeds them

Some researchers at the Technical University of Munich have built an unassuming but no-less-remarkable mechanism for tilting and panning a small camera robotically. Designed to keep up with the eye movements of a human in gaze-tracking studies, the camera mount features three degrees of movement, and can flick around at a rapid 2500 degrees per second -- our flesh-composed eyeballs max out at a mere 1000. The setup uses ultrasonic piezo-actuators, which move prismatic joints, which drive spherically-jointed rods attached to the camera, keeping the weight under 100 grams and still acting gently enough to avoid rattling on top of the wearer's head. We'll take two.
