A miniature camera is mounted in one of Toco's eyes (the same kind of camera that is used in Ripley and Trisk). Toco's mouth, eyes, and features are actuated by micro servos and were used for visual feedback of Toco's internal control system.

At certain frequencies, the soap film oscillates in symmetrical patterns called <a href="http://en.wikipedia.org/wiki/Normal_mode">normal modes</a>.<br><br> A light is reflected off the soap film through a lens onto the wall to show these normal modes as the frequency of the function generator is increased. The first set of normal modes occur at frequencies lower than we can hear with our ears, which is why you can't hear the speaker in the video until the frequency is increased. 268 tag:techtv.mit.edu,:Array/187074860 2009-07-07 11:45:24 -0400 MIT Department of Physics Technical Services Group A long beaded chain is looped over a motor pulley. When the motor is turned on, a disturbance in the chain causes waves to propagate through it. When the motor is brought up to full speed and the chain is knocked off the pulley it will maintain its shape for a few seconds and appear to "walk". 87
