Rovers for Moon and  Mars Exploration

Scientists are developing teleoperated systems for remote-controlled robots that could be used to explore the moon and Mars. These systems will allow human operators on Earth to control rovers, aiding in tasks such as digging and assembling.

Testing at ESA Facility  in England

Researchers from the University of Bristol tested their teleoperation system at the European Space Agency’s (ESA) facility in Oxfordshire. The system successfully manipulated a robotic arm to dig a sample of lunar regolith simulant using a virtual simulation.

Solving Signal Delay Issues

The system eliminates the need for camera feeds, which face a 1.3-second delay between Earth and the moon. Future signals for lunar missions could be relayed through ESA’s planned Moonlight project, ensuring smoother communication with robots.

Haptic Feedback for a Realistic Experience

The virtual simulation includes haptic feedback, allowing operators to feel the texture and resistance of lunar regolith. This feature helps improve control by mimicking the tactile properties of moon dust under low gravity.

Training Astronauts  for Lunar Missions

The teleoperation system could be used to train astronauts for future moon missions. The simulation provides a realistic experience, preparing astronauts for conditions they may encounter on the lunar surface.

Challenges of Trust in Virtual Systems

One challenge researchers face is building trust in the virtual system’s performance. Studies showed the system was efficient 100% of the time when scooping regolith and trustworthy 92.5% of the time during testing.

Potential for Mars Missions

While the system was designed for the moon, it could also be adapted for Mars missions. Teleoperated robots could assist in complex tasks such as retrieving samples from Mars for return to Earth.

Support for Upcoming Lunar Programs

The system could play a valuable role in supporting upcoming crewed and uncrewed lunar missions, including NASA’s Artemis program and China’s Chang’e program, by aiding in preparation and operations.
