A domestic robot is an autonomous robot that is used for household chores. Thus far, there are only a few limited models, though speculators, such as Bill Gates, have suggested that they could become more common in the future. Many domestic robots are used for basic household chores. Others are educational or entertainment robots, such as the HERO line of the 1980s. While most domestic robots are simplistic, some are connected to WiFi home networks or smart environment and are autonomous to a high degree.
