2輪型マルチコプタを用いた橋梁点検システム

抄録

We propose the bridge inspection system using a small size two-wheeled multi-copter. The multi-coper has two-wheels of the size 25 cm and can go into narrow space near bridge bearings. We also developed both a wheel driving system to move accurately at low speed on the ground in the narrow space and a camera gimbal device capable of controlling remotely to take close-up images of a bearing. A field examination in a water part of the river shows that the system is useful and practical for a bridge inspection and maintenance.
