  A robotic hand design suitable for dexterity should be examined using
functional tests. To achieve this, we designed a mechanical glove, which is a
rigid wearable glove that enables us to develop the corresponding isomorphic
robotic hand and evaluate its hardware properties. Subsequently, the
effectiveness of multiple degrees-of-freedom (DOFs) was evaluated by human
participants. Several fine motor skills were evaluated using the mechanical
glove under two conditions: one- and three-DOF conditions. To the best of our
knowledge, this is the first extensive evaluation method for robotic hand
designs suitable for dexterity. (This paper was peer-reviewed and is the full
