A suboptimal multimedia remote supervisory control of a robotic cell

This paper deals with the problem of developing a low cost remote supervisory control system with multimedia features of distributed robotic cells. The distributed robotic cells are locally controlled by different vendor systems. In the automated factories, a low cost and not isochronous backbone network is usually installed to transfer process data from the production level to the other ones. The proposed architectural prototype makes possible on different remote platforms a supervisory control with full process database access and field audio/video signal. The case of field vocal messages and animated plant synoptic using the low cost factory backbone network has been considered. On the remote station it is possible to use commercial supervisory control applications. A first case study, the remote supervision of a robotic cell, installed in the University of Naples, has given satisfying results. In addition, this application has shown the possibility of using the prototype for educational and research purposes, making available remote access to laboratories.
