Created by students from Harbin Engineering University, the robot underwent its first real test at a wind farm in Nanjing. Instead of magnets, it uses suction to avoid damaging the paint on the towers. It is still a prototype, completed in March 2026 by a young team.

A robot that climbs walls using suction has begun inspecting wind turbine towers in China, instead of sending a person up there. According to the report, the climbing robot was developed by a team from Harbin Engineering University, in Heilongjiang province, and underwent its first test in real conditions at a wind farm in Nanjing, in Jiangsu province. The machine carries up to five kilograms of sensors and has cameras that identify cracks, rust, and structural defects in the towers.

According to the material, the proposal is to replace the dangerous manual inspections performed by workers hanging dozens of meters high. The project began in July 2025, at the request of the company Nanjing Wind Power Technology, and reached a functional prototype of the robot in March 2026. Behind it is a team of eight people, including two professors and six students, with an average age of about 20 years.

The main advantage of the robot is the way it adheres to surfaces. According to the report from the portal China Daily, instead of using magnetic force, the equipment attaches by suction, allowing it to climb metal, glass, and other smooth vertical surfaces without damaging the protective coatings of the wind turbine towers. This is precisely a limitation of conventional magnetic adsorption systems, which can harm the paint.

The robot is the result of a group formed almost entirely by students. According to the material, the team has eight members, consisting of two professors and six students from the Xiaoping National Innovation and Technology Team at Harbin Engineering University, with an average age of around 20 years. Development began in July 2025, to meet a request from Nanjing Wind Power Technology, and the prototype was ready in March 2026.

For the young team, the responsibility came with a bit of anxiety. He Kai, a group member and first-year master’s student, said the team was “both excited and nervous” when they received the company’s request. He explained that the towers can be tens of meters high, making manual inspection risky and expensive, and that’s why the idea was to have a robot climb instead of people.

Hundreds of tests until climbing irregular walls

Getting the robot to actually climb required a lot of trial and error. According to the report, from the project conception to the first prototype, the team conducted hundreds of suction force tests and adjustments to the climbing algorithm. Each failure led to a small correction until the machine could move on irregular walls.

This process shows that the robot is still in the maturation phase. The result of so many test rounds was a device capable of moving on surfaces that are not perfectly smooth, a common challenge in weather-exposed towers. Even so, it is an advancement achieved in a research environment, now taken to the first field test.

From wind to ice, the next step for the robot

The robot also already has a planned next destination, and it’s colder. According to the material, the university has signed an agreement with the State Grid Heilongjiang Electric Power Company to use the technology in winter inspections of transmission towers and substations in Heilongjiang, where low temperatures make manual climbing especially dangerous. The idea is to take the equipment beyond wind turbines.

For Professor Zhang, the robot fits well in this extreme scenario. He stated that the device “is resistant to low temperatures and strong winds” and that the technology would help modernize the operation and maintenance of the power grid, filling a gap in high-altitude inspections in the province. It is worth noting that this broader use is still an agreement, not an operation already underway.

What still needs to be proven

Despite the enthusiasm, it’s worth looking at the robot with balance. For now, it is a prototype in its first test under real conditions, not a consolidated product used on a large scale. The promise of replacing manual inspections is a stated goal by the team, and the use in Heilongjiang’s winter depends on an agreement that still needs to be executed and tested over an entire season.

There is also the debate that usually accompanies this type of automation. Removing people from dangerous tasks at great heights is a clear safety gain, but replacing workers with machines raises questions about the future of these roles. The real test for the robot will be to maintain performance, require little maintenance, and function consistently outside the controlled research environment.

The Harbin climbing robot is a good example of how engineering tries to remove the worker from the most dangerous part of the job, high up on the towers. Even so, between the first test and large-scale use, there is a path of validation, durability, and costs to go through. If it delivers on its promises, the technology could change the way wind turbines and power towers are inspected, in China and beyond.

And you, would you trust a robot to inspect giant towers instead of a person, or do you still prefer the human eye? Share your opinion, respecting different views on the subject.
