Kinematics in the metric space

International audienceThis paper proposes a general method for driving kinematics by distances and more specifically for controlling kinematically articulated systems. Unlike traditional approaches, the problem is addressed in the metric space using distances belonging to points of the skeleton and to the environment. After defining kinematic control through a distance-based formalization, we propose an optimization method for solving classic issues such as motion adaptation and inverse kinematics. The originality of the method lies in the possibility to introduce distance constraints with priorities. The approach is validated by a large variety of experiments in the field of motion control of articulated figures, and compared to other approaches by means of stability, convergence and performance issues
