AIBO the Dog

The Sony Entertainment Robot Aibo (ERS-110), uses a combination of robotic and media technologies with machine intelligence to generates interaction with its operator. An examination of the Aibo hardware and software reveals how an inanimate object becomes a life-like companion. The Sony product name Aibo stands for Artificial Intelligence roBOt. It can respond to voice commands, detect obstacles, plays tricks, and more.
Aibo's personality develops by interacting with people. Each AIBO grows in a different way, based on its individual experiences. AIBO becomes customized based on feedback and the software being used.
Aibo's mood changes with its environment, and its mood affects its behavior. Aibo also has instincts to move around, to look for its toys, to satisfy its curiosity, to play and communicate with its owner, to recharge when its battery is low, and to wake up when its done sleeping. AIBO is capable of six feelings - happiness, sadness, fear, dislike, surprise, and anger. There are 28 LED lights on the Illume-Face display, and Aibo shows various expressions by changing the pattern of lights. Aibo uses its camera and microphone to remember your face and voice as its owner. The owner becomes special to Aibo, and it will respond to the owner.
