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, the image transmission time increases. In this paper, we describe a method for shorting the image transmission time by multi path communication system using LoRaWAN in order to improve the operability of mobile robot.
