QRIO ("Quest for cuRIOsity") was to be a bipedal humanoid entertainment robot marketed and sold by سونی to follow up on the success of its AIBO toy. QRIO stood approximately two feet (0.6m) tall and weighed 16 pounds (7.3 kg). On 26 جنوری, 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. QRIO's slogan was "Makes life fun, makes you happy!"

QRIO is capable of voice and face recognition, making it able to remember people as well as their likes and dislikes. A video on QRIO's website shows it speaking with several children. QRIO can run at 23 cm/second, and is credited in گنیز ورلڈ ریکارڈز (2005 edition) as being the first (and fastest) bipedal robot capable of running (which it defines as moving while both legs are off the ground at the same time). The 4th generation QRIO's internal battery lasts about 1 hour.
