Proposal of Single-Packet Mobile Robot Tele-Operation System Using LoRaWAN

Abstract

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 the robot. This paper describes a method to solve this problem by using LoRaWAN. In a wireless LAN tele-operation, the operator operates the mobile robot by using picture or movie information from the robot. However, in a tele-operation using LoRaWAN, operator can’t get that information by the low transmission rate. Then, we proposed a single-packet tele-operation method different from the conventional tele-operation method. In experimental results, we confirmed that the proposed method is effective for the tele-operation of mobile robot.
