Collective path generation without marking the environment

This paper reports current researches lead at Laboratoire de Robotique de Paris in the collective microrobotics field. The approach is based on multiagents behaviours adapted to microrobotics framework. A global problem is described concerning the management of colonies of microrobots and several elementary problems are brought out from it. Then, a solution to one of this elementary problems is presented. This solution explains how a colony of microrobots with very reactive individual behaviour can generate a path between two points (one of them is unknown at initial time). We avoid, with this solution, the problem of marking the environment in a microrobotics field
