Abstract
Impact acoustic approach is an effective method for inspecting the degradation diagnosis of the concrete surface. This paper presents a novel mobile robot for the impact acoustic inspection with its design and the impact motion mechanism. The features of the proposed mobile robot include impact motion without an additional motor not to obstruct the locomotion of the mobile robot, and the robust degradation analysis of the concrete surface in the noisy environment. In order to confirm the validity of the proposed robot, the experiments of the impact acoustic inspection by using the proposed robot is performed on a real concrete surface with floating damage.
