Development of Wireless Communication Status Monitor Function for Mobile Robot Tele-Operation

Abstract

At unmanned construction sites, machinery generally stops functioning or tele-operation is interrupted owing to the problems related to wireless communication. However, the entry of human workers into such sites is often restricted, making it extremely difficult for workers to resolve problems or restore connections in wireless communication. In this study, we interviewed personnel from relevant industries to identify common issues in wireless communication. To address these issues, we focused on improving the availability of wireless communication and proposed a wireless communication status monitoring function. The results from a prototype of the proposed function are also presented.
