A double pneumatic fin brake below the track slows carts as needed before they enter the boiler. For animatronics, synchronizing audio and action is the primary task. Sally Corp. engineers assemble frames for the exterminator figures. Plastic on stainless steel holds up better than conventional steel frames would in the fog of the dark ride. The success of a ride like the Exterminator depends greatly on putting the audience in the scene, Wood explained.
Action is directed at the riders as carts swing by individual animations.
We want the action to appear as though it's happening because of the rider's presence. The card holds a small amplifier as well, along with an animation controller. A sensor, detecting a cart, starts the show and the sequence, he said. The Exterminator consists of a number of short shows in the middle of one big show, he added. Any of the rides that Sally Corp. has worked on could have used central control.
