Title

Mobile Robots Against Gravity for Non-destructive Inspection of Infrastructures

Abstract

It has been a long-time dream to develop mobile robots with the ability to climb walls, walk on ceilings, crawl through pipes, and transit between horizontal and vertical surfaces, thus transforming the present 2D world of mobile rovers into a new 3D universe. This talk will first present the state-of-the-art of wall-climbing robots and then introduce the research progress and technical achievements at The City College of New York (CCNY) in developing novel climbing robots and the non-destructive evaluation (NDE) technologies. The wall-climbing robot prototypes include the City-Climber, Rise-Rover, and GPR-Rover to carry out inspection missions of infrastructure (dams, bridges, tunnels, and building fa├žade, etc.). The wall-climbing robots not only provide vertical mobility but also carry an RGB-D camera to detect surface flaws (i.e., cracks) and a ground penetration radar (GPR) to inspect subsurface defects (i.e., delamination). By using image processing, machine learning, and visual odometry techniques, the robot can localize and measure the surface flaws with high accuracy. By combining the robotic motion control with highly accurate positioning information, our approach disrupts the conventional GPR signal processing technique in analyzing and visualizing the GPR signal that allows the regular users easy to understand.
