Learning objectives

The aim of this course is to introduce the theoretical concepts and techniques for developing autonomous robot systems and in particular:
-the main sensor technologies and the techniques for processing sensor measurements;
-the robot control architectures and organization;
-the methods and techniques for the execution of complex tasks like navigation, manipulation and grasping, human-robot interaction by autonomous systems.
The course promotes acquisition of design skills like:
-to use different sensors (laser scanners, cameras, 3D perception systems) and to achieve a suitable representation of the environment from sensor measurements;
-to design and develop the control software of a mobile robot that is able to execute tasks in order to solve a specific problem;
-to use standard software tools and libraries to perform navigation, motion planning, manipulation and grasping, perception.


Computer programming and software development skills in C/C++ for Unix-like environment.
Geometry, linear algebra and mathematical representation of reference frames in space.
Basic notions about automatic control.

Teaching methods

The course consists of lectures and practicals in the laboratory.
During lectures the main concepts, algorithms and methods of Robotics are presented and illustrated with case studies, when possible.
The slides and lecture notes used in the course are weekly loaded.
Laboratory practicals enables the students to ascertain some of the proposed methods and topics using robots and devices, and to apply them to specific problems.
Beside the standard frameworks and software libraries commonly used in Robotics (e.g. ROS), source code is also provided through revision control systems (repository).

Assessment methods and criteria

The evaluation of the course consists of three examinations.
1) The written test, which contributes to 47% of the final mark, is organized into six questions or exercices. The knowledge of robotic concepts and the capabilty to apply algorithms and methods to simplified problems are assessed by such written test.
The duration of written test is 2.5 hours and the mark interval scale is 0-30.
2) The laboratory assignement, which contributes to 6% of the final mark, requires to program a mobile robot in order to execute a specific task. The assignment takes place as a competition among teams of two-three students. The assignment ascertains skills about problem solving, software programming with standard tools in robotics, and team working.
The outcome is binary (positive or non-positive).
3) The project, which contributes to 47% of the final mark, requires to develop a solution for a specific robotic problem. Project topics include perception algorithms (computer vision, range sensing and depth camera processing), demos with mobile robots or manipulator, software components for robotic systems. The project is carried out by students or by groups of two-three students. The project is concluded by a report and an oral presentation of the results. The mark value spans in interval 0-10.
