The Na'vi Shaman, formally the Shaman of Songs, is the animatronic figure who welcomes guests aboard the Na'vi River Journey in Pandora, The World of Avatar at Disney's Animal Kingdom in Florida, and when she debuted in 2017 Disney's own Imagineers and the technology press called her the most advanced animatronic the company had ever built. The numbers explain why. She carries 81 degrees of freedom, of which 42 are in the head alone, so her face can emulate emotion and convey feeling rather than cycling through a handful of canned expressions; each arm adds 9 degrees of freedom with independent shoulder movement and a total of 21 degrees of freedom in the body, so she animates her shoulders and scapula and reads as a body rather than a rigid mannequin. She stands 300 cm tall, measures 305 cm across and weighs 170 kg, and the mechanical reality behind that is dense: about 9,000 parts and 3,500 screws, an aluminium skeleton, custom silicone skin, and DC motors many of which are frameless and custom built. The control system is Imagineering's own, and its most important feature is defensive: real-time, model-based collision detection stops any commanded motion from causing damage, which is what makes 81 degrees of freedom safe to drive in a tight show space. She performs about 16 hours a day, 365 days a year, with very limited breaks, which is a harder engineering standard than most humanoid demonstrations face. This is not a product anyone buys; it is a character built to hold a scene in front of a continuous audience, and it is the clearest example of why Disney's animatronics programme sits alongside humanoid robotics rather than apart from it.
