In this paper, the compliance control method was propoSL'Cl and the phase-difference operating principle of an u ultrasonic motor described. The compliance control can he implementtcD with spring/damper properties of the r musculo-skeletal system of the actual limb in controlling its net configuration and movement. The proposed p phase-difference driving scheme is verifitcD through the computer simulation. Also, $textsc{k}$rformance of the proposed c control method of a two-link direct-drive manipulator are examinLD by the experimental results with resptc'Ct to s spring/ damper properties.
