AIBO (Artificial Intelligence roBOt, homonymous with "pal" or "partner" in Japanese: aibō (相棒^?)) was one of several types of robotic pets designed and manufactured by Sony. There have been several different models since their introduction on May 11, 1999 although AIBO was discontinued in 2006.

AIBO is able to walk, "see" its environment via camera and recognize spoken commands in Spanish and English. AIBO robotic pets are considered to be autonomous robots since they are able to learn and mature based on external stimuli from their owner, their environment and from other AIBOs. Artist Hajime Sorayama created the initial designs for the AIBO.

The original designs are part of the permanent collections of Museum of Modern Art and the Smithsonian Institution. The design won Sony and its designer Sorayama the highest design award that may be conferred by Japan. On January 26, 2006 Sony announced that it would discontinue AIBO and several other products as of March, 2006 in Sony's effort to make the company more profitable. It also stopped development of the QRIO robot. AIBO will still be supported until 2013 (ERS7 model) and AIBO technology will continue to be developed for use in other consumer products.
