Objectives
THE COURSE IS AIMED AT PROVIDING THE STUDENT WITH AN INTRODUCTION TO THE WORKING AND OPERATION PRINCIPLES OF UAVS (UNMANNED AIR VEHICLES), WITH EMPHASIS ON THE ASPECTS MOST RELEVANT TO THEIR MODELING AND SIMULATION. PART OF THE COURSE WILL BE DEVOTED TO LABORATORY ACTIVITIES WHERE STUDENTS ARE GUIDED IN THE DIMENSIONING, CONSTRUCTION AND CONFIGURATION OF A SMALL MULTICOPTER
AT THE END OF THE COURSE THE STUDENT WILL HAVE ACQUIRED:

KNOWLEDGE AND UNDERSTANDING:
INTERDISCIPLINARY KNOWLEDGE OF THE WORKING PRINCIPLES OF UAVS, UNDERSTANDING OF THE ARCHITECTURE AND COMPONENTS OF UAVS, KNOWLEDGE OF THE BASIC CONCEPTS OF UAV GUIDANCE AND NAVIGATION, BASIC KNOWLEDGE OF UAV EUROPEAN REGULATION.

APPLYING KNOWLEDGE AND UNDERSTANDING: ABILITY TO DIMENSION, ASSEMBLE AND CONFIGURE A MULTICOPTER;

AUTONOMY OF JUDGMENT:
THE STUDENT MUST BE ABLE TO DETERMINE THE MOST APPROPRIATE METHODOLOGIES FOR THE STUDY, DIMENSIONING AND CHOICE OF THE COMPONENTS OF UAVS.

COMMUNICATION SKILLS:
THE STUDENT IS REQUIRED TO ILLUSTRATE THE CHARACTERISTICS AND OPERATION OF UAVS USING AN APPROPRIATE AND CLEAR TECHNICAL TERMINOLOGY. THE STUDENT WILL ACQUIRE PROFITABLE KNOWLEDGE FOR APPROACHING THE JOB MARKET. TEAM WORKING, WITH AN INTERDISCIPLINARY APPROACH, WILL BE DEVELOPED.

LEARNING SKILLS:
THE STUDENT IS REQUIRED TO BE ABLE TO APPLY THE KNOWLEDGE ACQUIRED TO CONTEXTS DIFFERENT FROM THOSE PRESENTED DURING THE COURSE, AND TO FURTHER ELABORATE ON THE COVERED TOPICS USING TEXTBOOKS DIFFERENT FROM THOSE PROPOSED.
Prerequisites
FOR THE PROFITABLE ACHIEVEMENT OF THE COURSE OBJECTIVES A BASIC KNOWLEDGE IS REQUIRED OF THE NOTIONS TAUGHT IN THE COURSES OF FLUID MECHANICS, ELECTROTECHNICS AND MECHANICAL VIBRATIONS

Teaching Methods
THE COURSE CONSISTS OF A TOTAL OF 60 HOURS (6 CFU) OF TEACHING, DIVIDED IN: 34 HOURS OF LECTURES AND 26 HOURS OF PRACTICAL LABORATORY ACTIVITIES: THE STUDENTS, DIVIDED INTO GROUPS, WILL BE GUIDED IN THE DESIGN, CONSTRUCTION AND CONFIGURATION OF A SMALL UAV USING THE THEORETICAL NOTIONS INTRODUCED DURING THE COURSE.
Verification of learning
THE SUCCESSFUL ACHIEVEMENT OF COURSE OBJECTIVES WILL BE ASSESSED THROUGH AN ORAL INTERVIEW AND THE PRESENTATION/DISCUSSION OF A PROJECT. THE MINIMUM EVALUATION LEVEL TO PASS THE EXAMINATION (18/30), IS ACHIEVED WHEN THE STUDENT CORRECTLY MODELS UAV SYSTEMS AND HAS A SUFFICIENT KNOWLEDGE OF THE COURSE TOPICS. THE MAXIMUM EVALUATION LEVEL (30/30) IS GIVEN WHEN THE STUDENT PROVES HIS COMPLETE AND WIDE KNOWLEDGE OF THE OPERATING PRINCIPLES OF UAV SYSTEMS.
