When an active volcano erupts, it is important to observe in the area for forecasting debris flood and/or a pyroclastic flow for inhabitants. However, typically, a restricted area is set, such as within a few kilometers radius of the crater. Therefore, we proposed an observation system based on a tele-operated mobile robot via radio communication in active volcanoes. To evaluate the system, we conducted some field tests via 3G communication in Mt. Asama and Mt. Mihara etc. During the experiments, we faced some critical situations that the robot stopped all motion because of weakness of communication signal of 3G. To solve the problem, in this research, we developed a hybrid connection system with multi-robots that is composed of two radio communication lines. In this paper, we explain how the system works, introduce our new robots equipped with the system, and report operation tests on them.
