Magnetic Robot Begins Diagnostics at Russia’s Hydropower Plant
A newly developed magnetic robot is inspecting hydroelectric facilities to improve safety and reliability.
At the Bratsk Hydropower Plant in Russia, engineers have begun testing a unique magnetic diagnostic robot. The autonomous device, created at Irkutsk National Research Technical University, inspects the inner surfaces of penstocks—measuring metal thickness and detecting hidden defects.
The project marks an important step in Russia’s digital transformation and in strengthening the reliability of strategic energy infrastructure.
The robot can move across complex curved surfaces for distances of up to 150 meters. It is equipped with powerful neodymium magnets, cameras, ultrasonic sensors, and weld inspection tools. Unlike foreign counterparts, the robot operates fully autonomously—without a tether—making it more efficient in difficult industrial environments.
The Diagnostic Robot Extends the Life of Hydropower Plants
The project is supported by the En+ energy holding, which invested 11 million rubles (about $130,000) in the development. Early tests helped engineers enhance the robot’s design by improving its surface adhesion and refining the wheel-cleaning system.
Deploying this technology for industrial use is significant not only for Russia but also for the global energy sector. The robot provides precise data on the condition of hydraulic structures, helping prevent accidents and extend the operational lifespan of hydroelectric facilities.
Successful trials at the Bratsk Hydropower Plant pave the way for similar robots to be used at other power stations across the country.
