With the development of robot technology and the ever-increasing diversity in shapes of service robots, smart home and intelligent life gradually become a future way of life. The technology and system of service robots for smart home and intelligent life was proposed in this paper. Among many key technologies of the system, the cloud fusion technology for service robots and human-robot interaction technology with high degree of user experience were investigated in this paper. Take the home service robot as an example, the feasibility of the cloud-based architecture for the home service robotic system was verified with human-robot interaction experiments which are respectively based on WeChat and voice cloud. The proposed architecture for service robots is an implementation of smart home and smart living, and provides some valuable ideas for technical solutions of future service robots.
