上肢動作における立体作業城の設計要因

At present, the production systems in the Japanese industrial world are changing rapidly forward mechanization and automatic systems since industrial robots have been introduced. This is because the expense of workers has soared and the efficiency of the robots has improved while the securing of labor will become difficult in the future. As robots for production have been introduced, the main work for workers has become watching over the robots or controlling them. In other words, as the form of the man machine system has changed steadily. The work contents of workers have changed to operating switch buttons for the control panel of the robots. This paper presents a proposal to inprove productivity and provide a more reasonable workspace for the control panel. The method of research is to observe and measure the motion characteristics of the arm in the three dimensional workspace from a seated position. The valuation indexes used in the experiment are obtained by the amount of myoelectric discharge, the motion time, the motion velocity and the posture of movement. This paper showed that the influence of the workload became higher for the vertical direction. It also proposes the main factors for which need to be considered when planning a reasonable workspace with a high efficiency of work. The experiment formula shows the relationship between the motion time and the vertical direction.
