SISTEMI ROBOTICI E LABORATORIO

Module LABORATORIO

1. Knowledge and understanding. The course "Robotic Systems Programming" has the objective of providing the students with the knowledge on the principles, models, techniques and tools to program robotic systems and autonomous system in general. The lectures are based on teaching the principles of dyamic system modeling, automated control, control algorithms, and techniques and languages to program the autonomous behaviour of a robot. Laboratory activities have the aim of testing, in practice, all the topics dealt with in the classroom lectures.  
2. Applying knowledge and understanding. By means of the analysis of various case-study and with many laboratory exercises, the course allows students to obtain the capability of applying the techniques learnt during classroom lessons in applicative contexts based on robotic systems. Students will also able to unsterstand how to design and tune robotic control algorithms the specific application in which they it will be employed.
3. Making judgements. The lectures and, above all, the laboratory activities are organised in a way such as to include a critical analysis of some case-studies, with the relevant solutions considered with possibile variations, and pro and cons of them; the aim is to let the student acquire an adequate autonomy in the evaluation of technical choices.
4. Communication skills.The communication skills will be considered above all during the exams, here the student will be asked to expose her/his implementation choices providing suitable motivations for them.
5. Learning skills.  Learning skills will be evaluated during the laboratory. The aim is to test how and how much students have understood the basics of robotic systems and whether they are able to design and develop software for such kind of systems. The evaluatin of the learning skills will be then exploited to elaborate (if needed) the arguments that are revealed as the hardest.

Lessons are carried out in the classroom using a frontal approach by including also examples and exercises and by using both slides and the traditional backboard.
