We have been discussing a disaster information gathering system using mobile robot. There is a problem that an accident occurs on the robot in case of disconnecting the wireless LAN between the operator and robot. Then, we proposed wireless mobile robot tele-operation system using LoRaWAN as sub-communication infrastructure to solve the accident. LoRaWAN is superior to wireless LAN in communication distance, but inferior to bit rate. So, it takes a lot of time to transmit a large amount of data. In this paper, we describe the operation method using LoRaWAN as sub-communication infrastructure of ad-hoc network model without using large amount of data to solve the accident.
