Abstract: Abstract In this research, a vision-based wall-climbing robot is developed and discussed. In an electric power plant, a boiler is one of the most critical components, and the damage to this component can lead to a disaster in a power plant. Currently, boiler tubes are manually inspected to prevent damage and failure. The main damage in Cr-Mo tubes in a boiler plant includes fireside and internal corrosion that cause wall thinning. However, low carbon, overheating, creep, and hydrogen embrittlement are considered as the additional and primary damage mechanisms. It is observed that the creep occurs in low carbon steels for temperature over 400–440 °C, which is very common in boiler tubes. In Kazakhstan, the creep damage is the main reason for the tube failures. A regular inspection is crucial to prevent the damage to the boiler. In this paper, a robot is developed, which climbs vertically up to the end of the pipe and inspect the external surface of the tubes and pipes with the help of a camera. It consists of electronics and mechanical key components such as motors, controllers, sensors, and metal frames.
