Time delayed teleoperation has been one of the first and most challenging topics in robotic control. Although numerous methods have been developed by researchers all over the world during the last two decades, those methods have limitations or need special assumptions to be applied. With the development of the world-wide-web, teleoperation through the Internet sees a bright future. However, the...

In the past few years multilateral teleoperation systems that enable the interaction and coupling of several robotic devices gained in importance as this concept promises especially an increase of ergonomics and precision in teleoperation systems. The challenge in the control of such multi-robot setups is the generalization of the stability proof independent of the number of robotic agents invo...

In this paper, we discuss a novel control strategy for the bilateral teleoperation of multi-robot systems, by especially focusing on the case of Unmanned aerial Vehicles (UAVs). Two control schemes are proposed: a top-down approach to maintain a desired topology of the local robots, and a bottomup approach which allows changes of topology based on local robots interactions. In both cases, passi...

The performance of a wave-based teleoperator is heavily dependent on the amount of time delay present in the system. Although wave variables provide a very promising method to establish teleoperation in the presence of any time delay, tracking error in a wave-based teleoperator will be increased by increasing time delay. In this paper, we introduce a new method for reducing time delay effects i...

This paper presents a conceptual model of an agent (called Collaborator Agent) intended to design collaborative software architectures based on multi-agent systems. The authors’ model combines astutely two research areas: Multi-Agent Systems (MAS) and Computer Supported Cooperative Work (CSCW). The particularity of their approach is the division of the collaborative process into three spaces ac...

In master-slave teleoperation systems the control loop is closed through the human operator. He1 acts as a controller generating actuating signals based in visuat and kinesthetic cues. It is then indispensable to have a model of his behavior in order to design and study this type of systems coherently. Up to now only simplified arm dynamic models have been included in the study of bilateral con...

The aim of our research is to develop an industrial internet telecontrol architecture for robots in an active production line. The main objective is to realize teleoperation and telemaintenance tasks, which on the one hand meet user needs of the industry partners and can on the other hand be performed over the common Internet. The involved research fields are human supervisory control, networke...

Since teleoperation systems are mostly executed in the extreme environment, there are constraints in designing the mechanism and choosing sensors. This paper presents a novel quantitative comparison method of teleoperators based on H∞ framework. The upper H∞ norm bound of the system including H∞ sub optimal controller is used as the performance index. As a case study, the method is applied to a...

In this paper, a novel structure for a communication disturbance observer in teleoperation systems is proposed to achieve robust stability. A time delay compensation method based on the concept of network disturbance and a communication disturbance observer (CDOB) has been proposed in past research. Unlike model-based approaches, it works without a time delay model. Therefore, it can be impleme...
