Prerequisites
Students are expected to master the following skills: basic knowledge in description and analysis of mechanisms, mechanical manufacturing, analog and digital electronic circuits, electromechanical converters, and linear control, as they are covered within the courses LMECA1210, LMECA1451, LELEC1530, LELEC1310, and LINMA1510, respectively.
Main themes
The full and extended design of an autonomous mechatronic system.
Learning outcomes

At the end of this learning unit, the student is able to :

With respect to the AA referring system defined for the Master in Electro-mechanical Engineering, professional focus in Mechatronics, the course contributes to the development, mastery and assessment of the following skills:
  • AA1.1, AA1.2, AA1.3
  • AA2.1, AA2.2, AA2.3, AA2.4, AA2.5
  • AA3.2, AA3.3
  • AA4.1, AA4.2, AA4.3, AA4.4
  • AA5.1, AA5.2, AA5.3, AA5.4, AA5.5, AA5.6
  • AA6.1, AA6.3
The project mainly targets the acquisition of engineering skills similar to those being exploited in a mechatronics and robotics design office or department
a.      Disciplinary Learning Outcomes
At the end of this course, students will be able to:
1. Analyze a problem proposed by an external entity in the field of mobile robotics, and write its corresponding specifications
2. Achieve a pre-study of a mechatronics device and build up a pre-project: finding possible solutions, comparing them based on criterions from the specs, selecting the best solution, making a pilot mock-up, preliminary dimensioning, etc.
3. Conduct the detailed design of the selected mechatronics solution (or a mockup of the solution) including: the components dimensioning; the selection of standard materials and components (bearings, motors, gears, electronics, batteries, sensors, etc.); the production of a global drawing of the solution, and of detailed drawings for fabrication by using CAD software.
4. Design and implement an electronic system (typically with a FPGA and a microprocessor) providing a certain level of autonomy to a mechatronic system.
5. Program the autonomous functions of this system in an appropriate language and with a real-time operating system, towards the achievement of tasks planning and low- and high-level control of a mechatronic system.
6. Integrate the elements of the design into a functional prototype, build up, and assemble this prototype.
7. Build up a synthesis dossier presenting all technical details of the selected solution (global drawing, nomenclature, calculations, tests, electronic architecture, code) for the teaching staff.
b.      Transversal Learning Outcomes
At the end of this course, students will be able to:
8. Develop inventiveness while searching innovative solutions to an external problem.
9. Conduct a project in a group, requiring:
  • To rephrase some objectives.
  • To separate the basis problem into sub-tasks.
  • To evaluate the necessary resources for each task, and write down a working plan.
  • To distribute the work to be done within the group.
  • To maintain efficient communication within the group.
  • To make collective decisions.
  • To manage interpersonal relationships within the group, and to potentially solve conflicts in a constructive way.
10. Collect documentation and look for components from suppliers (describing the need, and selecting the most relevant component).
11. Perform a convincing public presentation by arguing on the decisions, in front of the teaching staff.
12. Perform a critical analysis of the functioning of a mechatronics device; anticipate possible failures and out-of-service causes
 
 
Content
An integrated project in mobile robotics, carried out by groups of 4 to 6 students. The practical terms and conditions are specified in the other sections
Teaching methods
Early in the year, students freely make group of 4 to 6 students. Each group has to make a robot fulfilling the yearly requirements of the 'Eurobot' robotics cup.
The pre-design goes on during the first half of the first quadrimester and is concluded by a presentation of the pre-project in front of the teaching staff. Thereafter, students achieve the detailed design of the robot, including the full dimensioning and drawings. The first quadrimester is concluded with the release of a technical dossier gathering all these elements. The rest of the year (2nd quad) is devoted to the fabrication of the electromechanical devices, their mounting, and to the programming (control) and tests.
Students are invited to participate to contests in order to compare their device performance to opponents: the Belgian qualifiers of the 'Eurobot' cup, during the Eastern break, and a local UCL cup, at the end of the year. A public overviewing presentation is also organized at the end of the year.
Throughout the year, students are accompanied by key resource people (assistants, technical staff) to deal with specific issues, such as the choice of a mechanical, electrical or electronic components.
Evaluation methods
Except exceptional situations, the evaluation takes the whole group performances into account. The following items will be accounted for:
  • the work done by the group during the whole year;
  • intermediate reports and;
  • final report;
  • global and fabrication drawings;
  • global functioning of the fabricated robot, and matching with the specs;
  • to a lesser extent, performances during the 'Eurobot' and UCL cups;
  • public presentations;
  • the answers given to the questions raised by the audience.
Caveat: some disciplines being practiced during the projects are mainly evaluated in associated courses (see the 'Prior skills' folder). The project evaluation mainly focus on the mechatronic design, control, and strategy
All students in a group whose work is judged insufficient in the June session will receive a failing grade for this course. This group will be asked to improve their work over the summer and resubmit it in the August-September session.
A student who has submitted work that is assessed as insufficient or of poor quality may also receive a failing grade as an individual, while the other members of the group receive a passing grade. In this case, the student concerned will have to complete additional work during the summer and present it during the August-September session. The content of this additional work will be determined by the teaching staff.
In accordance with article 72 of the RGEE, the teachers reserve the right to propose to the jury that a student who has not participated in the project or who has left his·her group during the year be refused registration for the examination relating to this course, including for the August-September session.
Other information
Students can occupy different rooms (the 'Faraday' lab and the adjacent mechanical workshop, both in the 'Maxwell' building), being equipped with standard tools and mechanical, electrical, electronic, and IT components. Borrowing this material during the academic year is secured through a financial guarantee for which modalities (amount and timing) are specified at the beginning of the year. The guarantee release is made only if rooms and materials are returned in a state in line with the internal rules signed by the students.
The pedagogical objectives and learning outcomes are reachable by using the electromechanical components provided by the teaching staff, a budget awarded to each group, and potentially a small personal contribution from students.
Bibliography
Des ouvrages de référence dans les domaines du choix des composants, de la mise en plans, et du dimensionnement électromécanique, sont disponibles à la bibliothèque.
Des catalogues de composants sont mis à disposition des étudiants. Tous les documents nécessaires à la poursuite du projet sont disponibles sur le site du cours (Moodle).
