The aim of our work is to control remotely mechanical systems which have nowadays local controls. With the development of the e-technologies, improvement of the network in term of time and band-width, the remote control will be common and will be made using networks without true quality of service, even unpredictable like Internet. In a first part of this paper, we are presenting some existing applications we have used. In a second part, we are describing generic software architecture to realize such remote control and a methodology to take into account the unpredictable nature of the communication media. In the third part we present experimental results of long distance remote control.
