Animatronics ( Engl. Animatronics - the phrase  animate "animate, animate, animate" (< Lat. Anima "soul") + electronics " electronics ") - a technique used in cinematography , animation , computer modeling to create special effects of moving artificial parts the body of a person or animal when it is necessary to create a complex layout , frame- by -frame shooting of which is impossible.
Small copies of real objects used to reduce the cost of filming. For example, the " Death Star " in " Star Wars " was less than two meters in diameter . Movable layouts are also used to create characters such as King Kong or dinosaurs.
Animatronic robot is a model programmed for all necessary movements, including facial expressions . The skeleton and servomotors controlling the model are hidden under artificial skin.
Hanging mock - up - used when in the background you need to depict a building of impressive size, the construction of which in full size would cost too much (for example, a tower). The decoration of the lower floors of the tower is built, then a model depicting the rest of the structure is suspended in front of the camera at a precisely calibrated distance. Thanks to the perspective effect , the layout is perceived as an organic continuation of the scenery . At the same time, it is important that the real decoration is of sufficient size so that the actions that must take place before the construction do not appear behind the layout.
