Autonomous robots dogs have been used to help maintain one of the world’s largest fusion energy research facilities, located in the U.K. These robotic canine helpers, deployed during a 35-day trial at the facility, can be both safer and more cost-effective, according to a spokesperson from the Atomic Energy Authority.

“This is the first time an autonomous robot has been deployed in fusion facilities for a long period of time,” Robert Skilton, head of robotics research and technology at the Atomic Energy Authority, said. “It established the reliability of robotic technology and how autonomous robots can be deployed safely inside fusion facilities.”

The robots are not affected by the challenging conditions that fusion energy facilities present, making them an ideal solution for improving efficiency while reducing risks to human operators. They have been tasked with carrying out regular maintenance inspections among the high radiation, vacuum-level pressures and extreme temperatures found at these sites.

“This work was about developing and demonstrating technology to help solve some of the fundamental challenges of maintaining future fusion power plants,” Skilton said. “It was about showing what’s possible today and building trust and confidence in the use of autonomous robotics for inspecting fusion facilities.”

Fusion energy, the same process used by the sun, is generated by smashing two atoms together to create a single, larger atom, releasing tremendous energy. While fusion holds the promise of abundant and clean energy, the technology is not yet commercially viable. Currently, fusion reactors consume more energy than they produce, which has been a key challenge for researchers.

However, advancements like the use of autonomous robots are helping reduce costs and improve operational safety. Experts believe these robotic systems could play a crucial role in making fusion energy more practical, potentially accelerating the timeline for its widespread adoption. Though fusion energy is projected to become a major part of the energy sector by 2050, further innovations are needed before it becomes a reliable and profitable energy source.
