The redundancy at this level of the tasks is due to a large number of degrees-of-freedom (DOFs) of the arm-hand system. This redundancy constitutes a big challenge to the planning and control tasks of the robot. For this kind of tasks, human has his own choices privileging certain configurations over the others. These choices come from a long learning process which implicitly takes into account the mechanical constraints of the system. In this work, we concentrate our effort on deciphering certain mechanical constraints, ”tenodesis” phenomenon in particular, in order to solve the redundancy and imitate the human natural gestures in the tasks of grasping or in-hand manipulation.application/pdfeng© IEEEconference proceedingsRobótica e Informática Industrial10.1109/IROS.2011.6094694open access145914642011 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS'11)
