An optical wireless communication system has been expected as a method of data and command transmission for mobile robots. The problems of the optical wireless system are interruptions for light beam by the structures in the plant, and necessity of precise tracking control of the beam direction. We developed the system composed of two communication stations, which called relay station and mobile robot station having the same structure. The developed system has functions of acquiring the other station and tracking it each other, and the communication with a rate of 130[Mb/s] for the mobile robot has been performed. Moving speed of 2.5[km/h], communication distance range from 1.5[m] to 10[m], pitching and rolling of 2[Hz], frequency, and 10 [degree], amplitude, are permitted. These performances are proved by experiments using the stations made for experiment.
