This two-year position is part of the ANR-JCJC project ToICar (Towards Collaborative Integrity for improved autonomy of a multi-robot system). The context of this project is the navigation of autonomous multi-robot systems. These are robots that can localize themselves in their environment, perceive it, interpret it without any human interaction, interact with other robots by exchanging relevant information and that make safe decisions to achieve their mission. However, so far there is no solution able to operate autonomously in different environments without human intervention. The integrity problem leading to the safety of mobile robots hinders their deployment. The notion of integrity is very important when autonomous navigation presents high safety risks where the probability of accident should be reduced as much as possible as in the case of autonomous vehicles . To do so, navigation requires an accurate and consistent estimation of the pose with reliable inputs from the perception system. However, dealing with this problem from a single robot perspective requires increased redundancy of high cost sensors at each perception and decision level. Hence, collaboration between robots appears to be an interesting approach that can lead to an accurate and high integrity solution thanks to the numerous and redundant information that can be shared .
The goal of this two-year research fellow is to advance the state-of-the-art by contributing to the design, development and testing of innovative algorithms in the fields of perception and localization for safe autonomous navigation of multi-robot system.
The challenges on which the applicant will focus are the following:
- Multi-sensors data fusion and integrity study of multi-robot system.
- The link between the integrity of the state estimation and the perception part (including learning) .
- Formulation of the uncertainty quantification problem in multi-robot systems.
- Adaptation of the state estimation method and development of fault identification in multi-robot systems (collaboration with a PhD student).
- Implementation and tests on real multi-vehicles datasets.
