Course Aim & Organization
This course will introduce basic concepts and techniques used within the field of autonomous mobile robotics. We analyze the fundamental challenges for autonomous intelligent systems when these move on wheels or legs and present the state of the art solutions currently employed in mobile robots and autonomous vehicles with a focus on autonomous navigation, perception, localization, and mapping.
The course is composed by a blending of lectures and exercises by the course teacher and a teaching assistant.
Lectures will provide theoretical background and real world examples. Lectures will be complemented with practical exercises in simulation for all the proposed topics and the students will be guided in developing the algorithms to control an autonomous robot.
Among other topics, we will discuss:
- Mobile robots kinematics,
- Sensors and perception,
- Robot localization and map building,
- Simultaneour Localization and Mapping (SLAM),
- Path planning and collision avoidance.

Course evaluation is composed by two parts:
- A written examination covering the whole program graded up to 27/32
- A home project in simulation practicing the topics of the course graded up to 5/32
The final score will sum the grade of the written exam and the grade of the home project.
In some (exceptional) cases the home project could be substituted with a lab project, possibly with a slightly higher grade, but this has to be motivated and discussed with the teacher.
In the course project you will use ROS to develop a simple autonomous mobile robot performing a simple mapping, localization and navigation task. The project requires some coding either in C++ / Python following what will be presented during the lectures. The project will be presented in two parts you have about one month to do each. Details will follow.

(Frequently) Asked Questions
In the schedule when it says ROS, are these lectures as well or are they practical work i.e. lab/excercise?
- They are ex-cathedra lectures where you are expected to bring your laptop, it is not mandatory and you can follow the class in a classical passive way, but I suggest to consider it as a lab and take your laptop with you if you can.
Out of all the scheduled activities this semester, approximately how many of these are practical lab/excercise?
- Indeed not all ROS lectures will present coding exercises, I expect half of them will be about coding and the other half more on the technical background you need to understand what you are coding.
Are there any solutions available for the past exams?
- No, if have doubts or questions, just send me your proposed solution and I will reply tailoring the answer to your current understanding.
Is it important to buy/read the text book to be able to follow the course? I can’t find it in the library, is there any alternative book?
- No, it is not required, as from past experience attending classes and checking the material provided y the teachers is enough. Obviously reading the book will provide much more information..
As I understand the “homework/project” is a group project. Is this correct and how are the groups formed?
- It is not a group project, while it is allowed to do it in groups (up to 3 people). I expect the groups to form naturally in classes. We usually setup a slack group for the project you can organize autonomously. Nevertheless you can do the project alone as well.
When “Part 1” of the homework/project will start?
- Right after we have finished the first block of lectures about ROS. This should happen around Easter plus/minus a week.
What is the biggest difference with the course 093217 ROBOTICS AND DESIGN?
- Robotics and Design is a practical course focused on the development of a robotics application, you will not learn about the theoretical aspects of robotics, but you will build a robot with a purpose which changes every year. I consider the two courses as complimentary.
Past Years Useful Material
Here you find material from past editions of the course that you umight find useful in preparing the exam.
Past Exams and Sample Questions
Since the 2015/2016 Academic Year the course has changed the teacher and this has changed significantly the program and the exam format as well. For this reason we do not have many past exams to share with you, they will accumulate along the years tho.
- Exam of 17/07/2017
- Exam of 01/07/2017
- Exam of 26/09/2016
- Exam of 05/09/2016
- Exam of 20/07/2016
- Exam of 27/06/2016
Past Course Project
Here you find past course projects in case you are interested in checking what your colleagues have been pass through before you. In some cases they may have been more lucky in some others you might be the lucky one ... that's life! ;-)
The 2018/2019 course project is divided in two releases. The homework philosophy should be "You have to struggle, but not too much!". Indeed the homework is made to challenge you and make you exercising and learn by doing, nevertheless if you find yourself stuck please write us and we will give you the required hints to continue and complete ... this includes extending the deadline (for all) or allowing you to use python instead of C++ (for selected students).
Advice: Start as soon as possible doing the homework!
- 2018/2019 Course Project Part 1: due on Wednesday 29/05/2019, this is the first part of the 2018/2019 course project.

The 2016/2017 course project is divided in two releases to provide you something to work on as early as possible during the course. The homework philosophy should be "You have to struggle, but not too much!". Indeed the homework is made to challenge you and make you exercising and learn by doing, nevertheless if you find yourself stuck please write us and we will give you the required hints to continue and complete.
Advice: Start as soon as possible doing the homework!

This year project is divided in steps; each of them is worth some points out of the 5/32 points available for the final mark. You find the project description here, it is complete, it contains parts up to 4, parts 5 is optional, but we suggest to do it anyway since it requires a limited amount of time.:

- 2015/2016 Kobra STL files: in case you want to make your simulation look more real here you find the STL files of the Kobra robot in the "Safer" version. Unfortunately the STL files are scaled down with respect to the real robot, so you have to modify those if you want to use.
If you are interested in a more deep treatment of the topics presented by the teachers you can refer to the following books and papers:
