In this paper, a three-fingered anthropomorphic robot hand, called SKK Robot Hand 1, is presented. By employing a two-DOF joint mechanism, called Double Active Universal Joint (abbreviated as DAUJ from now on) as its metacarpal joint, the hand makes it possible to mimic humanlike motions. We begin with addressing the motivation of the design and mention how the anthropomorphic feature of a human is realized in the design of SKK Hand I Also, the mechanism of the hand is explained in detail, and advantages in its modular design are discussed. The proposed hand is developed for use as a testbed for dextrous manipulation. It is expected to resolve the increasing demand for robotic applications in unstructured environments. We describe its hardware construction as well as the controller structure including the preliminary results of experiments.

In this paper, we present a new two-dof anthropomorphic joint mechanism that enables to mimic the humanlike motion. The proposed mechanism, called Double Active Universal Joint(DAUJ), generates a two-dof swivel motion without rolling by the coupled motion of two independent motor. In addition, we perform basic experiments to confirm the effectiveness of the proposed mechanism and the results are reported.
