The first drop of Audio-Animatronics was for Walt Disneys Enchanted Tiki Room in Disneyland, which open(a) in June, 1963. The Tiki birds were operate ond using digital controls; that is, something that is either on or off. Tones were recorded onto tape, which on playback would cause a metal reed instrument to vibrate. The vibrating reed would close a circuit and thus operate a relay. The relay sent a pulse of heftiness (electricity) to the figures mechanism which would cause a pneumatic valve to operate, which resulted in the action, the like the opening of a birds beak. Each action (e.g., opening of the mouth) had a neutral typeset, otherwise known as the natural resting position (e.g., in the case of the Tiki bird it would be for the mouth to be closed). When there was no pulse of energy forthcoming, the action would be in, or return to, the natural resting position.
This digital/tone-reed arranging utilise pneumatic valves exclusively--that is, everything was operated by air pressure. Audio-Animatronics groundss that were operated with this system had two limitations. First, the movement had to be simple--on or off. (e.g., The open and shut beak of a Tiki bird or the blink of an eye, as compared to the many opposite positions of raising and lowering an arm.
) Second, the movements couldnt require much force or part. (e.g., The energy needed to open a Tiki Birds beak could comfortably be obtained by using air pressure, but in the case of lifting an arm, the pneumatic system didnt provide enough power to accomplish the lift.) Walt and WED knew that this this pneumatic system could not sufficiently handle the more complicated shows of the Worlds Fair. A new system was devised.
In addition to the digital programming of the Tiki show, the Fair shows inevitable analog programming. This new analog system involved the use of voltage regulation. The tone would be on constantly throughout the show, and the voltage would be varied to create the movement of the...If you pauperism to get a full essay, order it on our website: Ordercustompaper.com
