With the development of robotic applications, service robots get into people's lives. But the robots themselves have limited computing capability, especially in processing the complex information received from different sensors. Thus it is not enough for a single robot to be competent to deal with the complex scenes. This paper proposes a cloud robot computing framework (CRCF), which combines the smart home facilities nearby and powerful hardware servers in the clouds. CRCF system platform is designed to take advantage of cloud's computing large data capability to extend the computing power and storage capacity of the robot. At the same time, CRCF system combines with third-party services and hardware to extend the sources of information and service functions of robots. Finally, through a remote control robot experiment, it verifies the CRCF system platform's capabilities and performance in combination with intelligent hardware and third-party cloud applications.
