A climbing robot capable of inspecting welds in nuclear reactor components faster than traditional methods. The system is designed to perform ultrasonic inspections of welds up to 30 centimeters thick in nuclear power plant reactors and steam generators. Traditionally, this process involves technicians manually moving scanners across the surface of the welds, a time-consuming and physically demanding task. The new robot automates this movement, allowing inspections to be completed far more quickly and with improved accuracy.
