Robot Fights Bridge Corrosion
Bridges are fundamental to transportation infrastructure worldwide, yet aging bridges often suffer from corrosion caused by de-icing salts, atmospheric carbon dioxide, and moisture seeping into small cracks. This corrosion poses significant risks, potentially leading to catastrophic collapses, but the damage typically isn’t apparent until it’s well advanced, resulting in costly repairs. Wouldn’t it be ideal if there were a way to catch corrosion early? Well, there is—and it’s been around for 25 years. A device equipped with an electrode attached to a rolling wheel measures the potential difference in reinforced concrete. Large differences signal that steel reinforcement bars are beginning to corrode. The downside? The current technology requires manual operation using a handheld stick, leaving hard-to-reach areas like support pillars and underbridges inaccessible.
To address these limitations, researchers from Switzerland’s Institute for Building Materials collaborated with the Institute of Robotics and Intelligent Systems. Their mission was to create a robotic solution capable of detecting corrosion in every corner of a bridge, even in areas unreachable by humans. They also aimed to detect corrosion at its earliest stages to minimize repair costs and prevent future disasters. Their solution was a versatile robot that could crawl walls, traverse ceilings, and move across flat surfaces. The robot uses Vortex technology: a propeller mounted beneath the machine generates enough suction to attach it securely to vertical or overhead surfaces, while wheels guide it across horizontal ones. Remote controls steer the device, ensuring precision in navigating complex environments.
This robot, initially called “Paraswift,†was designed four years ago with Disney in mind for its filming versatility. Now rebranded as “C2D2†(Climbing Corrosion Detective Device), it builds on the earlier electrode-on-a-wheel concept but integrates the electrode on its underside. A pink ball with a camera tops the robot, aiding obstacle detection and navigation while making it easier to spot during operations. C2D2 has already proven effective in identifying corrosion on several Swiss bridges, but the team envisions further advancements. By mid-2015, they hope to integrate autonomous navigation, eliminating the need for manual steering and enhancing obstacle avoidance.
C2D2 represents a promising step forward in combating infrastructure corrosion, though it isn’t alone in this field. Redzone Robotics, for instance, has developed robots since 2013 to inspect mid-sized sewer lines, identifying issues like corrosion and blockages. Rolls-Royce has been creating pipe-inspection robots since 1991, particularly useful in nuclear power plants. Other robots focus on coating pipelines to reduce leaks in gas and chemical lines. Meanwhile, Japan’s HiBot specializes in self-propelled devices to assess high-voltage power lines.
Corrosion remains a global infrastructure crisis, and as structures deteriorate faster than funds can be allocated for repairs, the $4 trillion maintenance gap widens. Innovations like C2D2 and HJ3’s carbon fiber systems offer hope in addressing this challenge by detecting and repairing corrosion early.

Infrastructure resilience depends on continuous innovation, and technologies like C2D2 bring us closer to safeguarding our bridges and beyond.
