metallic one instead of a plush cuddly toy. In fact manufacturers even found it pays to produce a toy that is essentially designed to be nurtured, rather like an egg in some 'parenting experience simulations', as proven by the success of the Japanese Tamagotchi. Commercial show robots For machines for the entertainment industry, cost is not the driving factor in design choices, and so the robots are often at a price point outside of what a private person would choose to pay These robots are made for use as: shop-front - created by a manufacturer to show what they are technologically capable of and so promote their other products. prop - inanimate performer or even artificial actor in show, TV and movie production (as the fictitious first toy robots, see above); as technology advances, some advanced robots can, often helped with other special effects, to make them seem what cannot (yet), even be significantly more than a cast extra, such as the droids R2-D2 and C-3PO in the Star Wars double trilogy (1977-2005) which have proved rather popular from the start. promotions - Used at trade shows where they move about a trade show floor providing tongue-in-cheek interaction with trade show attendees in order to bring said attendees to a particular company's trade show booth. exhibit - Robots such as Robothespian are used at venues such science museums to explain concepts or just be an interactive exhibit in their own right Non-commercial art robots In 1956, Nicolas Schöffer created Cysp 1 (Spatiodynamique Cybernétique), a robot and dancer working together to create an abstract sculpture and choreography with concrete music by Pierre Henry. These works could react to color, sound and light. Survival Research Laboratories, in San Francisco, California, creates large destructive robotic performances to roast contemporary culture and express their distaste for the military-industrial complex. Emergent Systems is creating large-scale interactive art environments where robots are able to respond to humans and each other as they react and evolve in the robotic installations. Autopoiesis was one such artificial life work that allowed a series of robots constructed of grapevines to both act as individuals and a group. Augmented Fish Reality allowed Siamese fighting fish to control their robots to meet across the gap of their glass fish bowls. Intel Museum hosts the A.I. driven interactive robot, ARTI, which is short for "artificial intelligence". This robot is considered to be a
