Offer Description

This Doctoral thesis is part of the NINSAR project (New ItiNerarieS for Agroecology using cooperative Robots), funded by the Agroecology and ICT PEPR (Priority Research Program and Equipment) and bringing together 17 French laboratories in Agroecology and Robotics.

The objective of the NINSAR project is to define new agroecological itineraries (new cultural practices, respectful of the environment and the soil, without chemicals), and to embody them in the collaborative execution of missions by a fleet of mobile outdoor robots.

The thesis will take place at LAAS-CNRS, Toulouse, from September 2024. The Institut Pascal (Clermont-Ferrand) and XLim (Limoges) laboratories will contribute to the supervision. Mobility is to be expected at the AgroTechnopole (INRAE Montoldre).

A function required for the collaborative execution of missions by a fleet of outdoor mobile agricultural robots concerns localization, including in the absence of GNSS signals: given a map of the environment (for instance, built up with natural landmarks), the robots localize themselves in an individual or concerted manner, e.g., by sharing their perception of common landmarks and/or by exploiting the fact that they perceive each other; when the map is no longer trustworthy, they establish a new one by running an individual or collaborative SLAM (Simultaneous Localization and Mapping).

A fleet of terrestrial robots in considered, equipped with proprioception and exteroceptive perception modalities, some of which can be controlled. The objective of the thesis is to develop opportunistic or active, individual or collaborative, localization and SLAM approaches, making it possible to overcome the scientific issues raised by the agricultural context: complexity and variability of natural environments, high level of precision and confidence required. in a wide range of situations, etc. Some methodological aspects addressed in the research team will be incorporated: modeling and inference in causal Bayesian networks; definition of (“greedy” vs “N-step-ahead”) policies enabling the optimization of an information-based criterion and operating in real time; joint learning of latent representation and optimal policy (prediction of agents and control of sensory modalities); etc.

The developed schemes will be systematically validated in simulation, then implemented on a fleet of robots hosted at the AgroTechnopole (INRAE Montoldre).

The innovative and multidisciplinary nature requires strong skills in all of the following disciplines: robotics, probabilistic modeling and inference, large-scale software development (software development infrastructures, etc.), perception, control, machine learning.
