From Remote Experiments to Web-Based Learning Objects: An Advanced Telelaboratory for Robotics and Control Systems

Abstract

This paper describes the current evolution of the telelaboratory facilities at the University of Pisa. In particular, starting from a standard environment providing remote access to a set of experiments, the telelaboratory is now organized as a collection of learning objects, i.e., modular didactic units designed following specific learning objectives within control systems and robotic fields. The telelaboratory has a remote Web-based access which can be used both as a simulation environment and as a remote way of performing real physical experiments. The developed telelaboratory is based on free open-source software such as Scilab/Scicos, Comedi, and real-time application interface patch for Linux kernels. In-house software tools, such as a Java Web hyper modular interface system, graphic environment tools, and a virtual laboratory interface based on Java applets, have been developed as a support for the learning process.
