Researchers are developing innovative remote-control robots and advanced simulations to assist future missions on the moon and Mars. These teleoperated robots will be able to collect critical materials like moon dust for future habitats and infrastructure. Teams from the University of Bristol have conducted successful tests of robotic arms manipulating lunar soil simulants, advancing technology for NASA’s Artemis Program and other space agencies’ lunar exploration efforts.

In the race to explore and establish a human presence on the moon and Mars, remote-control robots robots are emerging as a crucial technology that could transform how we handle resources and infrastructure in space.

New research from the University of Bristol has demonstrated the potential of remotely controlled robots in successfully simulating tasks like scooping and manipulating moon dust—a vital material that will be central to building future habitats on the moon.

Using cutting-edge technology, scientists at Bristol’s School of Engineering Mathematics and Technology carried out tests at the European Space Agency’s (ESA) European Centre for Space Applications and Telecommunications (ESCAT).

One of the biggest challenges of future moon missions is the handling of lunar regolith, commonly known as moon dust. This material is abrasive and electrostatically charged, making it difficult to manage. The University of Bristol's research team successfully demonstrated how teleoperated robots can be used to scoop, transport, and manipulate this vital material in a simulated environment, helping prepare for future missions like NASA’s Artemis Program and the ESA’s Moon Village initiative.

Using a haptic feedback system, the robotic arm provided teleoperators with a realistic sense of touch, simulating the low gravity of the moon and the tactile experience of moving lunar soil. As Joe Louca, the project’s lead researcher, explained, “We can adjust how strong gravity is in this model and provide haptic feedback, so we could give astronauts a sense of how moon dust would feel and behave in lunar conditions.”

This innovative feedback system allowed operators to feel how much force was needed to scoop and press into the regolith simulant. These realistic tactile interactions make the system highly accurate for simulating the difficult conditions astronauts and robotic missions will face on the moon. According to Louca, “The model predicted the outcome of a regolith scooping task with sufficient accuracy to be considered effective and trustworthy 100% of the time.”

These teleoperation experiments are part of a broader movement towards using robotic systems to assist astronauts and unmanned missions on the lunar surface. The simulation tools developed at the University of Bristol are expected to provide significant cost-saving benefits. Traditionally, lunar construction and resource extraction tests have required expensive physical simulants and access to high-end research facilities. However, this new simulation system allows developers and space agencies to conduct preliminary tests without the need for real lunar regolith.

As Louca noted, the model could also be used for astronaut training, providing a realistic virtual experience before crews embark on their lunar missions. “This simulation could be a valuable tool to support preparation or operation for these missions,” he said. The technology has the potential to serve not only as a training ground for upcoming Artemis missions but also as a tool for developing robotic systems capable of resource extraction on the moon.

The ability to teleoperate robots remotely is expected to play a crucial role in In-Situ Resource Utilization (ISRU), the process of using local resources to support human activities on the moon. Lunar regolith contains valuable components like oxygen and water, which could be extracted to provide life support for astronauts and fuel for spacecraft. Teleoperated robots would be essential for safely handling these resources in the moon's harsh environment, reducing the need for humans to perform risky tasks.

As space agencies prepare for crew missions to the moon in the coming decade, including NASA’s Artemis Program and China’s Chang’e Program, teleoperated robotics and simulations like those developed by the University of Bristol will play a vital role in ensuring that these missions are safe, efficient, and cost-effective. By advancing the field of remote operations, the groundwork is being laid for the construction of permanent lunar bases, which could one day support long-term human habitation and scientific research on the moon.

With teleoperated systems proving to be highly efficient, future missions will be better equipped to handle the moon dust, extract resources, and construct infrastructure that will enable humanity to thrive beyond Earth. “In the next decade, we’re going to see several crewed and uncrewed missions to the moon,” Louca said, “and this simulation will be a valuable tool in preparing for them.”
