L’article présente la méthodologie d’obtention de trajectoires optimales de marche pour une nouvelle classe de robot bipède. Le robot bipède est constitué de sept corps et possède des genoux anthropomorphes avec un contact roulant entre le fémur et le tibia. La marche est considérée comme une succession de phases de simple support suivi d’un impact. Une optimisation avec un critère énergétique ou sthénique est utilisé et le problème de recherche de trajectoires est transformé en une optimisation paramétrique. Les premiers résultats montrent que le robot étudié consomme moins d’énergie qu’un bipède conventionnel. This article presents the methodology to obtain optimal trajectories of gait for a new class of biped robot. The new robot has seven links and has anthropomorphic knees with a rolling contact between the femur and the tibia. The gait is described like a succession of simple support phase followed by an impact. An optimization with an energetic or sthenic criterion is used and the problem of finding gait is changed in a parametric optimisation. Early results show that the robot studied using less energy than conventional robot.

Article dans une revue avec comité de lectureHOBON, Mathieu; LAKBAKBI EL YAAQOUBI, Nafissa; ABBA, Gabriel (Elsevier, 2013)The design of humanoid robots has been a tricky challenge for several years. Due to the kinematic complexity of human joints, their movements are notoriously difficult to be reproduced by a mechanism. The human knees allow ...

Communication avec acteHOBON, Mathieu; LAKBAKBI EL YAAQOUBI, Nafissa; ABBA, Gabriel (2013)The knee of biped robots has usually one degree of freedom which one is a revolute joint. This work focuses on the study of rolling contact knee. The knee is composed of a cylinder in the extremity of the femur, rolling ...
