E-Laboratories development appears to be more complex than other e-learning contexts such as online courses, virtual classrooms, e-projects, role-playing, etc. However, this kind of training is essential for scientific and technical disciplines and fits a real need. Recently we initiated a project [A. Leleve et al., (2003)] whose main goal is to build a(More)
Long distance teleoperation over asynchronous transmission links makes many classical teleoperation schemes unstable. The use of this kind of media involves varying transmission delays that may become prohibitive even at short distance. However, they are standardized, cheap and widespread over the planet. This paper presents our latest works on the(More)
In this paper, we discuss the leap distance learning has to make in the near future. We take it for granted that students need hands-on approaches in addition to annotated lectures and simulations in the distance learning process. For now, distance learning relies mostly on ”top-bottom” teaching methods such as streaming lectures, but also on practical(More)
Over the last 50 years, master-slave teleoperation has become a widespread and successful field of research. This discipline explores how to perform tasks using a robot on an environment with haptic feedback about robot-environment interaction being provided to the human operator. Most of the master and slave manipulators used in teleoperation are(More)
This paper proposes a solution to control a remote manipulator robot (PUMA560) using IP network. A method is described to control this remote manipulator based on High-Order Sliding Mode so as obtain a product time delay bandwidth constant.Since previous method supposes a constant transmission delay, we put it over a low level mechanism (Network Delay(More)
A pneumatic actuator with solenoid valves is a discontinuous-input system because each valve can be either in on or off state. For such an actuator, this paper proposes a sliding-mode control scheme based on an averaged continuous-input equivalent model for the open-loop system. The averaged model is obtained from the nonlinear dynamics of the open-loop(More)
During last decade, Internet and related web technology development enabled the arising of e-learning services and made distant learning a reality. As traditional face to face classroom became virtual classroom through Internet, traditional laboratories found their image in Electronic Laboratories (ELABs). These ones enable learners to train themselves on(More)
This paper introduces a dual-user teleoperation system for hands-on medical training. A shared control based architecture is presented for authority management. In this structure, the combination of control signals is obtained using a dominance factor. Its main improvement is Online Authority Adjustment (OAA): the authority can be adjusted(More)
During last decade, Internet and related web technologies development enabled the arising of e-learning services and made distant learning a reality. As traditional face to face classroom became virtual classroom through Internet, traditional laboratories found their equivalent in e-Laboratories. These e-Labs enable learners to train on remote real or(More)
In this paper, we show that the integration of a new MES within an existing manufacturing system requires to appeal to a method enabling the modeling of interactions between hardware and software components, the modeling of their behavior and their use by production staff. We show how SysML is a language fitting this need and we illustrate this discussion(More)
