An entertainment robot is a robot that is not made for utilitarian use, as in production or domestic services, but for the sole subjective pleasure of the human. It serves, usually the owner or his housemates, guests, or clients. Robotic technologies are applied in many areas of culture and entertainment.
Expensive robotics are applied to the creation of narrative environments in commercial venues where servo motors, pneumatics, and hydraulic actuators are used to create movement with often preprogrammed responsive behaviors such as in Disneyland's haunted house ride.
