Approche bioinspirée pour le contrôle des mains mécaniques

Abstract : Works presented in this thesis are of multiple kinds but all aim at a better understanding of the human grasping movements, may it be from a behavioural, kinematics or control point of view. When one wants to grasp an object he relies on a multilayer control structure and its personal experience, the two of which allow him to estimate the appropriate move in a very efficient way, even before he actually started to move. We think that this type of command can bring forth an innovative solution to the double reach and grasp problem that face an artificial hand. We developed a distributed command architecture that reproduce in part these mechanisms and is able to control this type of artefacts in an efficient way, several versions of which were implemented regarding the desired control level. It consists of a group of matching units that takes inspiration in the Central Nervous System: each of them is in charge of a part of the global problem to be solved; they integrate data from the system inputs and/or from other units in partly redundant ways; and they rely on a supervised learning algorithm. In order to better understand the underlying principles of human movement we also took interest in hand and grasping movement models, may it be through an experimental protocol on human or monkey medical and video data analysis
