In this paper, a low computational cost method for terrestrial mobile robots that uses a laser scanner far following mobile objects and uvoiding obstacles is presented. In particular, the technique has been successfully implemented in the outdoor mobile robot Auriga-a. The measurement data from the laser scanner and the vehicle position are used as input variables. The outputs are the new curvature and velocity of the robot in order to follow a mobile object, or track U previously recorded path and avoid any possible obstucle in its way.

Learning Power Electronics is essential in both electrical and electronic engineering fields and the introductory courses are similar in many universities. Taking this premise into account, an educational computer-aided platform for power electronics will be presented in this paper. This educational platform includes an e-book, a set of power electronics animations, Java simulations, as well as several hands-on training sessions. The main advantages of this platform are twofold. First, all necessary teaching tools are combined on a single platform. And secondly, access to this platform is available free of charge and with no complicated registration requirements. In addition to traditional teaching techniques, the use of this platform has demonstrated an increase in student participation and has consistently improved their academic performance. Data consist of surveys, which guarantee both reliability and validity through psychometric techniques.
