Abstract: Dealing with the uncertainties of Internet characteristics is an important issue that needs being taken into account in developing Internet-based real-time systems. In this paper, we present our approach in applying fuzzy logic to develop back-up mechanisms for an Internet-based mobile robot to deal with unwanted network problems such as long delays or network interruptions. A tele-guidance application involving the remote control of a mobile robot via the Internet is set up as the context to verify the effectiveness and applicability of the proposed approach.
