Many infrastructures like bridges and tunnels had been constructed during the steep economic growth age. In Japan, degradation of those infrastructures becomes a problem. The main inspection method needs scaffolding under the bridge throughout, but it costs. Recently, Robots for the inspection has begun to attract notice. Inspection robots can cut cost and be safe. Inspectors must know the position where the robot captured the photo of damage. Therefore, localization system for robots is very important. Because, for example, a bridge inspection robot must be very compact, so localization system for the robots needs to be small and lightweight. In this study, we have created a localization system for the compact robots by using speakers and a microphone. This system consists of an analog circuit, an F PGA, a seven-segment display and a battery. However, It is necessary to mount only a microphone and the analog circuit on a small robot. The analog circuit with a microphone is very small and lightweight. First, we have performed experiments with only this system. As a result, it has been confirmed that this system can estimated the position. Then, we have mounted the microphone, the analog circuit and discrimination circuit on the small robot object and this system has estimate the position of the robot. According to the experimental results, the practical utility of this system has been confirmed
