— The time domain passivity framework is attracting interest as a method for granting stability in both telerobotics and haptic contexts; this paper employs this approach in order to introduce a novel concept, the Bilateral Energy Transfer for haptic telepresence. Loosely speaking, the Bilateral Energy Transfer is the straightforward transfer of energy(More)
Among the methods to grant the stability of a telemanipulation system , the bilateral time domain passivity framework has the appealing characteristic to consider both the forces and velocities signal exchanged between the master and slave systems, and the power introduced or dissipated by the elements that compose the whole telemanipulation system. In(More)
In an ideal case telepresence achieves a state, where a human operator can no longer dierentiate between an interaction with a real environment or a technical mediated one. This state is called transparent telepresence. The applicability of telepresence to on-orbit servicing (OOS), i.e. an unmanned servicing operation in space, teleoperated from ground in(More)
This article presents a method for passivating the communication channel of a symmetric position-position teleoperation architecture on the time domain. The time domain passivity control approach has recently gained appeal in the context of time-delayed teleoperation because passivity is not established as a design constraint, which often forces(More)
In this paper a trilateral Multi-Master-Single-Slave-System with control authority allocation between two human operators is proposed. The authority coefficient permits to slide the dominant role between the operators. They can simultaneously execute a task in a collaborative way or a trainee might hapti-cally only observe the task, while an expert is in(More)
— The paper proposes a general network based analysis and design guidelines for teleoperation systems. The electrical domain is appealing because it enjoys proficient analysis and design tools and allows a one step higher abstraction element, the network. Thus, in order to analyze the system by means of network elements the mechanical system must be first(More)
— This paper analyses the Time Domain Passivity Control approach in the time-delayed telepresence context, and proposes a method which provides stable operation. The passivity controller for the two-port network which is created by the bilateral control and communication elements in [1] is shown to be not valid if a time delay is introduced in the(More)
