Modelling of Virtual enviroments for training in teleoperated systems for dynamic enviroments

This research project is a continuation of a previous one (Automatic and Remote-Control Architectures Learning Systems) in which diverse tools were developed that let carry out tasks in a remote environment by means of advanced interfaces incorporation. From the designed architecture in the previous project, we have developed in the current one new research lines which focus on dynamic virtual environments incorporation to remote-control systems with the purpose that the operator can simulate the resultant effect of realise an specific action on the dynamic environment, before these actions really carry out in the remote environment. About the visual environment it is possible to simulate the behaviour of the remote-control system with different delays produced in the communication system once the environment’s dynamic has been incorporated. Likewise we have developed a totally open parallel architecture haptic device that has been incorporated as interface in the bilateral control diagram.
