2.2.3.8 Robots for Inspection
The Advanced Robotics and Automation (ARA) Laboratory from the University of Nevada, Reno developed a series of robots for inspection of bridges and bridge decks. The robot is coupled with several sensors capable of acquiring different sets of data. The robots have demonstrated successful mapping of surface cracks, detection of subsurface objects, and thickness measurements in case studies [28]. As Figure 10 shows, employing the robot allows inspectors to perform activities from a safer distance, drastically reducing exposure to passing traffic and equipment. While the robots developed by ARA are mainly focused on bridge inspection, several of the features can also be applied for pavements.
