In today's busy young people, soaking feet seems to set up a luxury behavior. The high time cost of adding water, boiling water, pouring water, cleaning and other steps deter them. For the elderly who love foot bath more, heavy buckets and manual cleaning are heavy physical work, not to mention the imbalance when accidentally wetting the ground with water and wiping the feet... On the basis of smart home and Internet of Things, in line with the attitude and belief of serving people, FOOTOBOT will be a new concept of redefining "foot bath" in the home scene. Unlike other products on the market, it will try its best to implement the concept of service robots to the end, replacing the previous human behavior: receiving water, boiling water, handling, massage, drying, pouring water, cleaning. Under the linkage with other smart homes, the matter of "foot soaking" will be fully entrusted to the FOOTOBOT to make decisions and implement the FOOTOBOT robot. Through the linkage and intercommunication with the smart door lock, smart audio or butler robot, the user will be judged whether the user is at home, whether he is busy or not, and the position at home, so as to plan a family foot bath service in combination with heating time and walking route.
