Researchers at the U.K.'s University of Lincoln (UoL) designed an end-over-end walking (E-Walker) robot for space construction projects. The E-Walker robot features seven degrees-of-freedom motion capabilities. UoL's Manu Nair and colleagues conducted an exercise in which they tested the E-Walker on the in-orbit assembly of a 25-meter (82-foot) Large Aperture Space Telescope. Nair said, "The proposed innovative E-Walker design proves to be versatile and an ideal candidate for future in-orbit missions. The E-Walker would be able to extend the life cycle of a mission by carrying out routine maintenance and servicing missions post assembly, in space."

A New Walking Robot Design

Researchers have created a cutting-edge walking robot that might revolutionize large space construction projects. They tested the feasibility of the robot for the in-space assembly of a 25m Large Aperture Space Telescope. Their findings were recently published in the journal Frontiers in Robotics and AI. Furthermore, a scaled-down version of the robot has shown potential for large-scale construction applications on Earth.

Maintenance and maintenance of massive structures are particularly important in space, where the circumstances are harsh and human technology has a limited lifetime. Robotics, autonomous systems, and extravehicular activities have all proven helpful for servicing and maintenance missions and have assisted the space community in conducting innovative research on a variety of space missions. Robotics and autonomous systems advancements provide a wide range of in-space services. This includes, but is not limited to, manufacturing, assembly, maintenance, astronomy, earth observation, and debris removal.

Nair and his colleagues presented a new, dexterous walking robotic system that could be used for in-orbit assembly missions in their paper. As a use case, the researchers tested the robot for the assembly of a 25m Large Aperture Space Telescope (LAST).

Assembling telescopes in orbit

Ever since the launch of the Hubble Space Telescope and its successor, the James Webb Space Telescope, the space community has been continuously moving towards deploying newer and larger telescopes with larger apertures (the diameter of the light collecting region).

Assembling such telescopes, such as a 25m LAST, on Earth is not possible with our current launch vehicles due to their limited size. That is why larger telescopes ideally need to be assembled in space (or in orbit).

“The prospect of in-orbit commissioning of a LAST has fueled scientific and commercial interests in deep-space astronomy and Earth observation,” said Nair.

Due to the many hazards involved, relying just on human builders is insufficient, and current technologies are outdated. “We need to introduce sustainable, futuristic technology to support the current and growing orbital ecosystem,” explained corresponding author Manu Nair, Ph.D. candidate at the University of Lincoln. “As the scale of space missions grows, there is a need for more extensive infrastructures in orbit. Assembly missions in space would hold one of the key responsibilities in meeting the increasing demand.” Nair and his colleagues presented a new, dexterous walking robotic system that could be used for in-orbit assembly missions in their paper.

To assemble a telescope of that magnitude in space, we need the right tools: “Although conventional space-walking robotic candidates are dexterous, they are constrained in maneuverability. Therefore, it is significant for future in-orbit walking robot designs to incorporate mobility features to offer access to a much larger workspace without compromising dexterity.
