In recent years, the Sustainable Development Goals (SDGs) have tended to attract attention. In Japan, Society 5.0 has been proposed as a vision that is linked to the achievement of the SDGs, and various organizations are promoting this vision. In particular, “i-Construction” is being promoted in the construction industry, and productivity is increasing as a result. Moreover, it is important for operators to have a sense of achievement and motivation for their work through their active operation. In this study, we propose a control system that automatically adjusts the assist rate according to the person in assist control. A control system that can adaptively adjust the assist rate is constructed by utilizing work data to evaluate the difference from the desired characteristics. The proposed method was implemented on a hydraulic excavator and its effectiveness was verified.
