Estimation of operational force based on ground reaction force and human behavior for power-assisted attitude control system on overhead crane

In recent years, aging population is becoming serious problem in Japan. In manufacturing industry, a system which can help elder workers is desired. In this research, we propose a power-assisted system to help elder workers handling overhead crane. In previous study, the power-assisted system for vertical and horizontal travelling was constructed, however, attitude control system was not completed. In this paper, we propose an estimation method of operational force as basic study to realize power-assisted attitude control system on overhead crane.
