Offer DescriptionContext and objectivesThe offer is proposed within the frame of “PROMETE” project (Planning autonomous robots for eco-friendly construction sites) supported by the “Projets collaboratifs I-Démo régionalisé” program and co-funded by the Region Normandie, the French government (France 2030) and the European Union (FEDER). This project is carried out by a consortium of four academic and industrial partners including Heracles Robotics ( ) as a leader. It aims to automate construction machines to increase their efficiency and reduce their carbon footprint.The aim is to equip these machines with sensors enabling them to analyse their environment, plan their movements and interactions with other machines on-site, and carry out their tasks quickly and accurately. The methods developed must guarantee the safety of the machines when working alongside other machines, as well as their robustness in the face of terrain variations and ageing. As a partner in the “PROMETE” project, IRSEEM's Control & Systems team, is tasked with proposing robust predictive control laws to ensure that planned tasks are carried out accurately and rapidly.MissionsIn collaboration with the project's members, the 24-month-recruited Postdoctoral Researcher will have a number of tasks involving modelling, control, and implementation of the resulting control algorithms. These tasks are divided into three main parts, more or less sequential. * The first task involves modelling the construction machines under consideration. This modelling will be carried out using a geometric approach, in particular through the use of the notion of Lie group [1]. Indeed, a construction machine can be considered as a sequence of joints placed on a mobile robot [2], thus justifying this type of modelling. Different types of machines will have to be modelled, and the parameters will then be obtained using data from our partners in the project.
  • Based on these models, the second part of the mission will be to develop Lie group-based predictive control laws [3, 4, 5, 6, 7]. These control laws will be used to improve the precision, speed, and fuel consumption of the machines studied. To achieve this, an economic model predictive control approach will be used [8].
  • Finally, the third part of the mission will seek to make the predictive control laws previously studied robust [9, 10]. Indeed, the machines under consideration are subject to significant parametric variations as they age. Thus, the considered control strategies will have to be adapted to compensate for these parametric uncertainties [11, 12, 13].
In parallel with these tasks, the person recruited will be studying methods for tuning the parameters of predictive control laws. These methods are based on the use of reinforcement learning algorithms [14, 15]. The methods developed will be deployed on our partners' construction machinery. Experiments on several regional sites are planned. Finally, the person recruited will contribute to the supervision of interns involved in the project.References * F. Bullo and A. D.
