Me

I am currently an engineer for the experimentation and development for research department (Service d’Expérimentation et de Développement SED) and mainly working on the Auctus robotic plateform.

I did a Postdoc from 2021 to 2022 at the joint lab between CNRS and Solvay called the Laboratory Of the Future. This Postdoc was conducted in collaboration with the Auctus team. The goal of this project was to introduce a robotic assistant inside a glovebox. To know more about this project you can go here.

From 2019 to 2021 I worked on the Harry² project in the Auctus team. From 2015 to 2018 I did my PhD in medical Robotic under a Cifre contract between General Electric Healthcare and the Institute of Intelligent Systems and Robotics of the Sorbonne Univeristé. In 2015 I received a master degree in Mechatronics from the Ecole Normale Superieur de Cachan.

My research

My research is focused on the expression of control laws for robotic manipulators to realise complexed tasks in a dynamic environment. To do so I use quadratic programming problem formulations. This allows to respect constraints that can be intrinsic to the robot (e.g the joint position limits, joint velocity limits, …) or extrinsic (e.g virtual walls, …) while performing a set of tasks as best as possible. I apply these control laws in the field of safety.

My fonctions

Since I arrived in the Auctus team, I helped extend the experimental platform in parallel of my research. To do so, I developped the control architecture of the two Franka Emika panda robots, including the many sensors used around it (RGBD cameras, laser sensor, F/T sensor, …). This control architecture mainly uses ROS with the many tools along side.

I developped two libraries to formulate QP problem for robot manipulators at the joint velocity and torque level: torque_qp and velocity_qp. All the softwares developped for the team are open source and free of use and can be found here.

I’m also handling the technical aspects of the Auctus team (wifi, computer inventory, …).

Finnaly, I’m administrating the Auctus gitlab with Vincent Padois.

Positioning and Objectives The Inria Center at the University of Bordeaux hosts various research teams that incorporate robots into their projects (e.g. Auctus team or Manao team). The Experimental and Development Service (SED) is responsible for establishing and maintaining the experimental platforms of the center, including the maintenance of its robots. These robots operate within ecosystems that encompass various sensors such as cameras and lasers, and they are controlled using the ROS … [Read More]

The Auctus team was asked to perform a demonstration of our work during the Village Sports & Science in Bordeaux. We used the same demonstration that we did during the robotcup to over 2300 visitors. [Read More]
Context Recent progresses in robotics, which tend toward assistive systems or versatile collaborative robots, could make a reorganization of industrial sites possible in order to preserve the health of human workers, by improving their working conditions, while enhancing the value of human expertise and skills. Such a transformation of work requires to rethink robotic control approaches, both in terms of safety and physical capabilities, to enable the robots to help humans in their activity and … [Read More]
