Approaches and Issues Regarding a Child Body Center of Mass Behavior in an Exoskeleton Design

This research addresses to find a suitable design solution in order to model the behavior of human center of mass and implement this in an exoskeleton structure especially designed for children walking assistance and rehabilitation. One of the most general problems on exoskeleton designs is represented by the ground – foot contact on exoskeleton behavior under kinematic and dynamic conditions. Thus, for solving this, the main research objective is to develop a mechanical system which will substitute the human center of mass CoM behavior on an exoskeleton especially designed for children with Duchenne Muscular Dystrophy. The research core focuses on modelling the human CoM behavior under kinematic circumstances and transferring this through a mechanical system conceptual design. The obtained results will validate the proposed mechanical system through a comparative analysis between numerical processing, virtual prototyping and experimental specific methods and procedures.
