Impedance Control of an Action Support 6-Degree-of-Freedom Manipulator : On-Line Learning Method of Impedance Parameter Considering Forgetfulness(Mechanical Systems)

Abstract

This paper proposes a control system for action support manipulators. A 6-degree-of-freedom manipulator is controlled with an impedance control. Impedance parameters are tuned by on-line learning with a force sensor. The learning rule is convenient and considers forgetfulness on handling. The proposed method is applied to a meal support manipulator as one application example. A weight between position control and force control is used to carry the hand to the mouth surely. Usefulness of this method is verified through experiments.
