| Popis: | This master thesis subject takes place at the company Colas, one of the world’s leaders of road creation, especially in France, and more precisely in its subsidiary Aximum, specialised in road equipment. Among all their business, road painting is a consequent part of road creation: however, the technological means employed in the process seem outdated and do not follow the technological improvements that could improve their quality of work life. In order to improve the working conditions of the road painters, Aximum’s innovation team started a project to conceive the prototype of a robotic assistant to road painting. Located on the side of the vehicle, an electrically actuated cylinder would place the machine’s painting guns directly on the road line to be re-painted. The algorithm part relies on computer vision with the help of a 3D camera to detect road lines. The software ROS (Robot Operating System), was chosen as the global framework of the project, linking the different elements of the system, ranging from motor drivers, to Python scripts and GUI (global user interface). Once the road line is detected by the algorithm, it calculates a distance to be travelled so that the camera and the painting gun are totally aligned with the road line. A prototype was built following this concept. Steel parts were designed on CAD software so that the actuation part fits with the concept of a painting vehicle. After four months of programming and building the prototype, the solution worked and fulfilled its purpose as a proof of concept. However, the solution as such appeared to be limited on some aspects and some changes of paradigm seemed to be necessary for the system to be better fit with the task at hand Objectius de Desenvolupament Sostenible::9 - Indústria, Innovació i Infraestructura |
