In May 2005, a groundbreaking achievement in underwater robotics was realized when the TB-1 dam safety detection robot, developed by Professor Sun Enfang from Harbin Engineering University, successfully passed the acceptance test conducted by the expert group of the national "863 Program" robot technology subject. This marked its official launch into practical use, setting a new standard for dam inspection technology in China.
The TB-1 robot is equipped with high-resolution imaging capabilities that allow it not only to identify minute surface cracks on dams but also to detect internal cavities and accurately assess the extent of damage. It can operate at depths of up to 300 meters, making it suitable for inspecting all types of dams across China—ranging from large to small. Additionally, the robot is capable of navigating vertical structures and complex horizontal formations buried under silt, adapting well to both clear and turbid water environments—something that traditional underwater robots could not achieve.
Experts praised the TB-1 as the first multi-functional integrated underwater detection system in China, combining underwater imaging, structural inspection, topographic mapping, and internal damage assessment. This innovation represents a major leap forward in the field of dam safety monitoring, offering a more efficient, accurate, and versatile solution compared to previous methods. Its introduction has significantly improved the ability to maintain and monitor the integrity of critical infrastructure, ensuring safer and more reliable water management systems.
