Development of dexterous robot hand for delicate object grasping

Abstract

Our goal is to develop the 13 DOF dexterous robot hand. For this, we designed a new robot hand by improving previous developed robot hand and by analysis of human hand. This robot hand is the type of motor driven and includes a fingertip tactile sensor, a joint torque sensor, fingertip 6-axis-force-torque sensor and an embedded board. For performance evaluation of a designed robot hand, we worked analysis of workspace, intersection volume, manipulability, opposition angle and Kapandji Test. Also, we compared our robot hand with Shadow Hand, Gifu Hand III. And we worked a simulation by applying an Impedance Control.
