Robotic systems have been developed to handle very small objects, but their use remains complex and necessitates long-duration training. Simulators, such as molecular simulators, can provide access to large amounts of raw data, but only highly trained users can interpret the results of such systems. Haptic feedback in teleoperation, which provides force feedback to an operator, appears to be a ...

In order to help the user to accomplish a task, teleoperation systems have to integrate different tools such as visualization, divers interaction devices, planning tools, etc.... The interface must be able to give complete information of the real world and the user can, using a distributed platform, be helped by others users as well as by autonomous robots. The objective of our project is to co...

Purpose – The objective of this study is to enhance the usage of teleoperation fields, such as in nuclear site decommissioning or nuclear waste disposal, by designing a stable, dependable and fault-tolerant teleoperation system in the face of “extraordinary” conditions. These “extraordinary” conditions can be classified as variable time delays in communications lines, usage of different robotic...

Most of the methods to date on bilateral control of nonlinear teleoperation systems lead to nonlinear and coupled closed-loop dynamics even in the ideal case of perfect knowledge of the master, the slave, the human operator and the environment. Consequently, the transparency of these closed-loop systems is difficult to study. In comparison, inverse dynamics controllers can deal with the nonline...

Time delay is a serious problem for bilateral teleoperation systems. Even a small time delay in a bilateral teleoperation system will generally degrade the system’s performance and cause instability. An important approach that guarantees stability for any fixed time delay is the wave variable method. In this paper we present some recent material dealing with teleoperation systems using wave var...

In this paper, we examine teleoperation as a critical aspect of using mobile robotic telepresence systems. Particularly, we propose and advocate using cognitive architectures as means to ease teleoperation for novice users and to enhance social interactions.

Teleoperation has captured the interest of robotics researchers for more than two decades. Many focused on the stability problem when the system experiences time delays. Most of the time, guaranteeing stability has overshadowed the tracking performance. This work differentiates teleoperation systems into two groups as limited and unlimited-workspace teleoperation depending on their position tra...

Teleoperation can be significantly improved if humans and robots work as partners. By adapting autonomy and human-robot interaction to the situation and the user, we can create systems which are easier to use and better performing. In this paper, we discuss the importance of collaboration and dialogue in human-robot systems. We then present a system based on collaborative control, a teleoperati...

For deactivation and decommissioning (D&D) of contaminated structures in the weapons complex, remotely operated robotic systems are expected to replace human workers from hazardous radiation and difficult work environments, while improving productivity and reducing costs. Nevertheless, the major drawback of currently available remote operation technology is that teleoperation is a slow and impr...

The existence of time delay in the communication link is one of the most important problems regarding the stability of teleoperation systems. Time delay is specially relevant in ground teleoperation of robots orbiting Earth, with values of round trip delay ranging from 5 to 10 seconds. Many proposals on how to conduct time delayed teleoperation under various circumstances and for different appl...
