Postdoc Optical analysis and navigation of magnetic microrobots in a labyrinthine environment by artificial intelligence (M/F) nt labyrinthique par intelligence artificielle (H/F)

Job Description

Missions

This research program aims to develop an experimental platform dedicated to the analysis and optimization of magnetic microrobot trajectories in complex environments from optical imaging data. Magnetic microrobots are aggregates of magnetic nanoparticles that self-assemble in rods in the presence of an applied magnetic field. These microrobots are able to move in a liquid medium following the application of a rotating magnetic field of a frequency, amplitude and polarization precisely adjusted according to the trajectory to be achieved by the microrobot.
The objective of this project is to set up a system capable of detecting, monitoring and analysing in real time the movement of microrobots evolving in constrained structures of the labyrinthine type. The trajectories of the microrobots will therefore be programmed from the known relationships between the movement of the microrobots and the control parameters (frequency, amplitude, polarization, etc.). Subsequently, the acquired image streams will be processed using advanced computer vision techniques based on convolutional neural networks (CNNs). The resulting trajectory data will then be integrated into an algorithmic planning module based on pathfinding methods such as the A* algorithm. The integration of these approaches will lead the candidate to the development of a dynamic correction system capable of adjusting the trajectory of microrobots in real time from the continuous analysis of visual data.

Activity

• Setting up an experimental system consisting of an electromagnetic circuit and the network of microfluidic channels with an in situ generation of magnetic microrobots
• Develop a program (preferably in C++) to generate sequences of electrical signals that power the electromagnetic circuit and generate a good configuration of the magnetic field that can make microrobots move along a set trajectory in a labyrinthine microfluidic network.
• Develop image analysis tools to detect and track microrobots in motion.
• Design algorithms (e.g. A*) to optimize maze navigation while respecting the maximum latency of 1s.
• Implement real-time processing with machine learning to correct trajectories.

• Enthusiasm and passion for fundamental research and innovation and motivation to work in an ambitious and high-growth sector.

Your Work Environment

INPHYNI's activities are based on three main axes: Waves and quantum physics; Photonics; and Nonlinear Physics, Complex Fluids and Biophysics. The projects developed around these themes cover theoretical, fundamental and experimental aspects as well as applications. These projects benefit in particular from the support of technological platforms and efficient administrative and technical shared services. Experimental activities are supported by two technological platforms belonging to the institute: Optics and Photonics and Soft Matter, the latter including a clean room. The institute's common services include a chemistry lab, a mechanical shop, and an electronics shop.
The position is located in a sector under the protection of scientific and technical potential (PPST), and therefore requires, in accordance with the regulations, that your arrival be authorized by the competent authority of the MESR.
