In the social context of an aging workforce at the labor intensive manufacturing sectors, we discuss an assisting system for older workers who have excellent skills though their physical ability to perform iterative tasks at a constant speed with high quality. "Skill-Assist" which is proposed in this paper is a new type of assisting system which varies its mechanical impedance to give workers who have been working under the lifetime employment system a sense of achievement in being again able to accomplish the skilled tasks they were capable of when younger. This paper discusses the control algorithm of Skill-Assist. First, a criterion for changing the impedance of Skill-Assist in response to task condition variations is explained to propose. "Phase-Dependent Impedance Control". Second, desirable impedance patterns are experimentally determined. The patterns are required to produce a good subjective operational feel and precise positioning when maneuvering Skill-Assist. Finally, the effectiveness of Skill-Assist is verified under more practical positioning tasks, which is evaluated based on the subjective operational feel, physical stress, and productivity.
