For a few years, Electronic Laboratories (ELabs: computer-aided local laboratories as much as distant and virtual ones) have been growing in the E-Learning panorama. Meanwhile, in major E-Learning activities, learning scenarios are nowadays written in a standard way (SCORM, IMS-LD) to be used by standard Learning Management Systems. The use of such(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)
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)
Similar to classical in-situ laboratories, remote laboratories are necessary in e-learning environments, especially in scientific and technical disciplines. This paper outlines our current research on this particular way of learning. Our research objectives consist in proposing a generic framework (independent of educational content) to allow, in one hand,(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)
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)
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)
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 model-ing 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)
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)
