Sony's aibo ERS-1000 is an AI-powered robotic companion dog with 22 axes of movement and two cameras (front and SLAM) whose behavior develops a unique personality through experiences with its owners and environment. Announced in November 2017 and launched in Japan in January 2018, it is a consumer entertainment/companion robot still sold in 2026 through Sony's own stores in Japan and the US, with a mandatory aibo Basic Plan sold alongside the body.
Sony has ended aibo (ERS-1000) sales; ¥272,800 was the final list price on Sony's own aibo store. Support/cloud plans for existing owners continue — resale value now depends entirely on the second-hand market.
