Hierarchical impedance-based tracking control of kinematically redundant robots
A Dietrich, C Ott - IEEE Transactions on Robotics, 2019 - ieeexplore.ieee.org
The control of a robot in its task space is a standard approach nowadays. If the system is
kinematically redundant with respect to this goal, one can even execute additional subtasks …
