Electrolocation is the name given to the sensor ability for certain electric fish robots, which are able to detect electrostatic perturbations caused to the presence of some objects in their neighborhood. This ability to interpret an electrical signal to locate itself in space opens important perspectives, including in the field of biologically inspired robotics. Mathematically, electrolocation is linked to the electric impedance tomography: so it's about a non-linear inverse problem, particularly ill-posed problem. We will, in this Phd, study some methods of reconstruction, which could be obtain robustly some characteristic of the obstacle's shape, rather all of their geometry details. So, it's about to study the stability between the observable part of the obstacles and the errors of measurements.
