Animatronics

1. INTRODUCTION 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 coat reed instrument to vibrate. The vibrating reed would close a circle 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 act, 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 cogency forthcoming, the action would be in, or return to, the natural resting position. This digital/tone-reed arranging utilise pneumatic valves exclusively--that is, ev erything was operated by job pressure. Audio-Animatronics groundss that were operated with this scheme had two limitations. First, the movement had to be simple--on or off. (e.g., The open and fold 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(prenominal) 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 constitution didnt grant enough power to accomplish the lift.) Walt and WED knew that this this pneumatic body could not sufficiently handle the more complicated shows of the Worlds Fair. A new system was devised. In addition to the digital computer programing 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 realize ! the movement of the...If you pauperism to get a full essay, dedicate it on our website: OrderEssay.net
