With the fast development of the internet technologies, the interaction between the traditional robotics and the advanced network technologies has become increasingly far-reaching. The intention of this paper is to investigate the status and development of the web-based robotics technologies. In the first part of this paper, the concept of web-based robotics has been introduced. Then it not only analyses the technical kernel of web-based robotics, but also illustrates the related applications in this area. Some research topics in the web-based robotics are also proposed.
