Abstract
Dynamic characteristics of a human extremity are usually expressed using the mechanical impedance. This paper examines hand impedance in dual arm movements while posture was maintained in dual-arm configurations. The results of experiments show that the orientation of viscosity ellipses roughly agrees with the human sagittal axis, tending to be oriented similar to stiffness ellipses. Viscosity and stiffness amplitude and orientation exceed those of single arm. Our results will be used in human-robot cooperation systems and in analyzing human movements.
