Field Experiment Report of Tunnel Disaster by Investigation Robot System with Passive Adaptive Crawler Robots

Abstract

This paper describes about the concept design and the lessons learned from a field experiment of the tele-investigation robot system for the tunnel disaster proposed by authors. In Japan, a new project “robot technology and robot system for next-generation social infrastructure” was started in 2014 by MLIT (Ministry of Land, Infrastructure and Transport). The features of this project are that providing actual field (bridges, tunnels, dams, rivers, landslides site and volcanic disaster site), and performing a field demonstration and experiment of robots. The proposed robot system was selected as one of technique in the field for tunnel disaster investigation for this project. A field experiment was performed in order to evaluate the core technologies of the proposed robot system at the imitation tunnel facilities of the NILIM (national institute for land and infrastructure management) in Tsukuba (Japan) on January 7 and November 5, 2015.
