A domestic robot is a robot used for household chores. Thus far, there are only a few limited models, though science fiction writers and other speculators have suggested that they could become more common in the future. For example, in 2006, Bill Gates wrote an article for Scientific American titled 'A Robot in Every Home', supporting this idea. Many domestic robots are used for basic household chores, such as the Electrolux Trilobite, Roomba and the SLAM based Neato Robotics vacuum cleaner robot. Others are educational or entertainment robots, such as the HERO line of the 1980s or the AIBO. While most domestic robots are simplistic, some are connected to WiFi home networks or smart environments and are autonomous to a high degree. There were an estimated 3,540,000 service robots in use in 2006, compared with an estimated 950,000 industrial robots.
