Investigation of Driving Principle of Non-Electrically Driven Robots Using Sound Waves as a Power Source

The method of repairing concrete in hazardous areas such as nuclear power plants has not been established yet. Although many robots have been proposed to work in hazardous areas, they have problems such as not being able to operate wirelessly and being left as debris when an accident occurs. We aim to investigate the feasibility of a robot that uses its own structure as a repair material using a non-electric actuator. In this paper, we investigated the feasibility of a robot that operates using sound waves as a drive source without using electricity as the first attempt. Through several experiments, we confirmed that the developed robot could be controlled arbitrarily even if the installation location changes.
