The course is entirely taught in English. The students who complete this course will gain knowledge on fundamental concepts in robotics, dealing with both industrial and mobile robots. Industrial robots will be studied both from a kinematic and dynamical point of view. Independent-joint and inverse-dynamics control algorithms will be introduced, as well as fundamental algorithms for the generation of reference trajectories. Mobile, wheeled robots will be studied from a kinematic point of view, and algorithms for locomotion control and path planning will be defined and studied. Elements of sensors and computer vision for robotics will complement the knowledge base of this course.

The course requires the knowledge of the basic elements of geometry in the Euclidean tri-dimensional space, the ability to use rigid roto-translations; knowledge of the different ways to represent the orientation/attitude of a rigid body; capacity to solve simple cases of roto-translations of rigid bodies in 3D. Also, knowledge on basic simulation techniques and software tools, such as Matlab/Simulink, is strongly suggested. A suitable background for all these topics is provided by the course 02PCYQW, "Modelling and simulation of mechatronic systems". Furthermore, the knowledge of elements of automatic control (linear control theory, PID schemes) is strongly suggested. The instructor is available to provide students with material to make up missing background elements.

Theoretical foundations of each topic will be given in traditional in-class lectures. In-class lectures will be complemented by exercises and simulation examples, which will be partly solved in class and partly left to students for completion as homework. Practical exercises in class and in the laboratory will be devoted to model simple robotic structures, using Matlab, Simulink and ROS.

Modalità di esame: Prova scritta (in aula);
Exam: Written test;
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
Exam: Written test;
Specific learning outcomes are assessed through the administration of a final written exam. Knowledge items will be assessed through the administration of theoretical exercises and problems concerning the theoretical foundations of robotic systems. Abilities will be assessed through the administration of numerical exercises and problems, as well as through the design, analysis, or modification of software elements, written in the programming languages studied in class. The exam consists of a written test, aimed at assessing the comprehension of the theoretical concepts and the ability to apply them to practical case studies. The test consists of two sections: - the first section comprises 10 to 15 multiple-choice questions; - the second section comprises 3 to 5 problems. Such problems can be open-answer questions, numerical problems, coding problems. The first section contributes for the 40% of the written test mark, and the second one for the remaining 60%. Incentives and penalties on the final marks will be given to students, in an amount not greater than the +/-10% (+/-3 pts), based on the active participation to the laboratory activities. Students abroad for study reasons and other particular cases will be evaluated on a case-by-case basis. The exam is closed-books, closed-notes. Students are allowed to take with them a single A4 sheet, compiled on both sides with notes and formulae at their wish. The exam duration is 2 hours. Students who would like to gain more practical insights on the topics covered in the course, may propose to the instructor the realization of a project. A project must be executed by a team of 3 to 5 students. Project topics will have to be agreed upon and approved by the instructor. The project outcomes must be presented to the instructor in the agreed form, generally through either a report or a presentation. Individual contributions must be clearly stated and identifiable. Projects are not mandatory, they do not substitute any part of the written test, and will be evaluated up to an additional 10% of the full marks (3 pts).
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
