Abstract
When a human user operates multiple mobile robots, it is difficult for him/her to obtain much information simultaneously from robots. In this paper, we propose a method of displaying visual, force, and sound information effectively in order that a human user could operate the robots with less load. The displaying information consists of operation guidance for the arrangement of the robots around an object, transportation guidance for transporting the object, and work guidance for precise movement. With these guidances, the user deals with excess information and controls the multiple robots effectively. We built a real system and verified the effectiveness of the proposed method and the system in experiments.
