Prof. Sébastien Briot

My main research interests include the design optimization of robots and the analysis of their performance, especially their singularities, and their eco-sustainability.

In particular, for the singularity problems, I worked on:
- the analysis of the singularities of rigid-link parallel robots from a dynamics perspective, proposing criteria to pass through them, then allowing the robot to access to normally unaccessible workspace areas,
- the singularity analysis of certain classes of controllers, like visual servoing problems or controllers related to drone fleets,
- the definition of the singularities of continuum parallel robots, and of sagging-cable-driven parallel robots.

For the eco-sustainability part, I developped design methodologies:
- for designing robots rigid links made traditionnally with metals or carbon composites by plant-based bio-sourced materials with very low environmental footprints
- for considerably decreasing the energy consumption of high-speed robots.
