A Positioning Mechanism of a Robot for Automatically Imaging of Underground Buried Infrastructure-facilities

Abstract

We have proposed automatic inspection robot mechanism to enable the inner images in facilities only by operation from the ground without a person entering. To move the camera module at the observing point, we examined the positioning mechanism as a key device. The positioning mechanism with the robot arm and L-shape guide part was developed.

We applied the robot mechanism to image the manhole inside space of telecom-infrastructure facilities. We confirmed that a whole high-resolution image of the upper floor slab in a manhole could be obtained.
