Abstract: A system for collecting and distributing information to and from a plurality of electronically controlled machines. The system is designed to collect information from robots, industrial machines, and other types of equipment that produce real-time information. The machines are coupled to a data collector module using a public domain communication protocol. The data collector module is coupled in data communication to a main server which has a mechanism for publishing the data received from the electronically controlled machines over a network to one or more clients. The main server also has an authenticator for verifying the identity of clients accessing the system through the network, and a communication module for streaming the data from the electronically controlled machines. Information and programming may also be transferred from the clients to the machines through the system to allow remote control of the machines.
