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...

Guiding a remote vehicle when real time image transmission is not possible is an important problem in the field of teleoperation. In such a situation, it is impractical to put an operator behind a steering wheel and expect accurate steering. In semiautonomous teleoperation, an operator designates the path that the vehicle should follow in an image of the scene transmitted from the vehicle, and ...

With the widespread use of wheeled mobile robots (WMR) in various applications, new challenges have arisen in terms of designing its control system. One of such challenges is caused by wheel slippage. This paper proposes a new method for haptic teleoperation control of a WMR with longitudinal slippage (not including sliding). In this teleoperation system, the mobile robot’s linear velocity foll...

This paper provides less conservative stability conditions for bilateral teleoperation by exploiting the advantages of the integral quadratic constraint (IQC) framework, where the environment can be defined as a memoryless, bounded, and monotonic nonlinear operator. Recent advances in multiplier theory for appropriate classes of uncertainties/nonlinearities are applied. Since the classes of mul...

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...

This paper describes experiments of Internet modeling and of Internet-based teleoperation aimed at developing control laws to overcome the variable time-delay and data losses typical of Internet communication. From a control perspective, Internet is shown to be characterized by mean and jitter of the data packets delay, and by packet losses. Furthermore, these parameters depend on the number of...

A novel control algorithm based on the modified wave-variable controllers is proposed to achieve accurate position synchronization and reasonable force tracking of the nonlinear single-master-multiple-slave teleoperation system and simultaneously guarantee overall system's stability in the presence of large timevarying delays. The system stability in different scenarios of human and environment...

Teleoperation technology allows to remotely operate robotic (slave) systems located in hazardous, risky and distant environments. The human operator sends commands through the controller (master) system to execute the tasks from a distance. The operator is provided with necessary (visual, audio or haptic) feedback to accomplish the mission remotely. In bilateral teleoperation, continuous feedba...

Many complex tasks (search and rescue, explosive ordinance disposal, and more) that eventually will be performed by autonomous robots are still performed by human operators via teleoperation. Since the requirements of teleoperation are different from those of autonomous operation, design decisions of teleoperation platforms can make it difficult to convert such platforms for autonomous use. In ...

A construction robot generally includes some actuators, and has sufficient power to carry out tasks that are difficult for humans. The application of such robots in environments that are dangerous for humans such as disaster scenes, space and the deep sea ground is becoming more and more important. Teleoperation is the most effective method of controlling these robots, and teleoperation systems...
