[abstFig src='/00280002/03.jpg' width=""300"" text='Rail structure supporting mechanism' ]Human workforce working at the Fukushima Daiichi Nuclear Power Plant face severe health and safety risks owing to the presence of radioactive obstacles and debris caused by the accident and the subsequent shutdown of the plant. Under such circumstances, various robots are deployed to undertake many tasks, however, it is not easy for robots to realize smooth locomotion and efficient operation because radioactive debris and architectural structures such as steps and doors tend to hinder their movement. In addition, installable sensors and actuators are restricted in such an environment. To overcome these difficulties, we propose an automated construction system with modularized rail structure for robot locomotion and operation. The structure is anchored to walls or floors and enables working robots to reach a specific destination. This paper describes the development of a rail structure supporting mechanism. The developed mechanism applies resin foam to three different components: the actuator, adhesive material, and structural material. To our knowledge, these multi-modal applications of resin foam are quite unique and novel. Basic experiments were conducted using the developed prototype. Experimental results verified the feasibility of pillar expansion, anchoring, and fixation motions, and they also revealed the impact of the components' properties on the performance of the supports.
