| 摘要： | According to the American Society of Civil Engineers, there are over 617,000 bridges across the country, 42% of which are 50 years old or more. Not only are they aging, but 7.5% of all the nation's bridges are considered structurally deficient. Given the number of vehicles on the roads each day, inspection of America's infrastructure is top of mind. Traditionally this process involves costly inspections, potential damage to the asset, and disruption to the flow of traffic. Today, new robotic technology makes inspections more efficient, more accurate, and safer for inspectors and the motoring public. Two rapidly growing areas of adoption for robotics include the inspection of bridge stay cables and high mast light poles (HMLP). Traditionally, the exterior of bridge stay cables are visually inspected by rope-access climbers (inspectors) who harness themselves to the bridge stay cable. In randomly selected locations, cable wedging is performed to inspect the interior of the sheathing for possible deterioration or corrosion of the stay cable. Ironically, cable wedging allows for additional moisture to penetrate the sheathing, causing further corrosion and/or deterioration of what inspectors are trying to properly maintain. |
