QRIO' ("Quest for cuRIOsity", originally named Sony Dream Robot or SDR) was a bipedal humanoid entertainment robot developed and marketed (but never sold) by Sony to follow up on the success of its Aibo entertainment robot. QRIO stood approximately 0.6 m (2 feet) tall and weighed 7.3 kg (16 pounds). QRIO's slogan was "Makes life fun, makes you happy!"
On January 26, 2006, on the same day as it announced its discontinuation of Aibo and other products, Sony announced that it would stop development of QRIO. Before it was cancelled, QRIO was reported to be going through numerous development, testing and scalability phases, with the intent of becoming commercially available within three or four years.
