 Aperios OS was intended to be widely deployed using revolutionary real-time capabilities to handle multiple audio and visual data streams concurrently The operating system was not widely adopted, and by 2003 Sony had stopped active development with COO Kunitake Ando commenting "Aperios was an operating system of a pre-Internet age and we decided that it isn't adequate for the future".The OPEN-R architecture is specific to entertainment robots.The architecture involves the use of modular hardware components, such as appendages that can be easily removed and replaced to change the shape and function of the robots, and modular software components that can be interchanged to change their behavior and movement patterns.
