چکیده

There are over six hundred thousand bridges in the U.S. which require great amount of human effort along with expensive and specialized equipment for maintenance. Current bridge inspections are manually performed by inspectors which are inefficient and unsafe. This paper presents visual and three dimensional (3D) structure inspection for steel bridges and steel structures using the developed climbing robot. The robot can move freely on steel surface, carry several sensors, and collect data then send to the ground station for real-time monitoring as well as further processing. Steel surface image stitching and 3D map building are conducted to provide a current condition of the structure.

Design and Development of a Flexible Steel Surface Climbing Inspection Robot

Motivated by a high demand for automated inspection of civil infrastructure, this paper presents a novel design and development of a tank-like robot for structural health monitoring. Unlike most existing magnetic wheeled mobile robot designs, which is only suitable for climbing on flat steel surface, our proposed tank-like robot design uses reciprocating mechanism and roller-chains to make it c...

A Cross Structured Light Sensor and Stripe Segmentation Method for Visual Tracking of a Wall Climbing Robot

In non-destructive testing (NDT) of metal welds, weld line tracking is usually performed outdoors, where the structured light sources are always disturbed by various noises, such as sunlight, shadows, and reflections from the weld line surface. In this paper, we design a cross structured light (CSL) to detect the weld line and propose a robust laser stripe segmentation algorithm to overcome the...

A climbing autonomous robot for inspection applications in 3D complex environments

Often inspection and maintenance work involve a large number of highly dangerous manual operations, especially within industrial fields such as shipbuilding and construction. This paper deals with the autonomous climbing robot which uses the "caterpillar" concept to climb in a complex 3D metallic-based structures. During its motion the robot generates in real-time the path and grasp planning in...
