Orbiting astronaut oversees robot team on Earth

Astronaut Frank Rubio aboard the Worldwide House Station collaborated with a small crew of robots on Earth to perform a fancy process—a primary take a look at of a brand new method to mix human and robotic capabilities for our return to the moon and past.

The 2-hour telerobotics take a look at passed off in a simulated planetary atmosphere within the German Aerospace Heart, DLR, at Oberpfaffenhofen close to Munich. Working from Europe’s Columbus module, NASA astronaut Frank Rubio directed a trio of robotic property to take away a seismometer from a lunar lander and place it on the bottom to detect moonquakes.

Frank served as overseer for the robotic crew, engaged on a “level and click on” foundation. He took direct control as wanted utilizing a force-feedback system. A DLR robotic lander arm was mixed with DLR’s Rollin’ Justin humanoid robotic and ESA’s four-wheeled, two-armed Work together rover.

The aim is to make clear what astronauts want when working robots with various ranges of independence, referred to as “scalable autonomy.” This method permits astronauts to have extra management over the robots.

Within the take a look at state of affairs, the primary within the “Floor Avatar” collection, a caught pin needed to be faraway from the lander earlier than the seismometer might be positioned by Justin. In the meantime the Work together rover had been broken by a quake throughout a floor sampling operation, in order that the pattern nonetheless caught in its gripper wanted to be retrieved by Justin and be positioned on the lander.

Within the occasion, Frank achieved all of the duties in time, whereas additionally giving the crew priceless suggestions on options of the person interface and the robots. These might be carried out and validated within the subsequent session of Floor Avatar in January 2024.

This primary take a look at opens the best way to a follow-up Floor Avatar take a look at with a bigger crew of robots, deliberate to be undertaken by Danish ESA astronaut Andreas Mogensen throughout his Huginn mission later this 12 months.

The distances concerned in spaceflight make it impractical to carry out direct distant management of robots on the moon or different planetary surfaces from Earth. As a substitute, the concept is to have astronauts in orbit management these robots—to discover and take motion on the moon, then later different alien environments, with out the associated fee and threat of touchdown.

“Our METERON undertaking undertaken with DLR, proved the feasibility of this force-feedback management method from native orbit, increasing to work with astronauts on the ISS and culminating in an outside marketing campaign within the moon-like atmosphere of Mount Etna in Sicily,” explains Thomas Krueger, head of ESA’s Human Robotic Interplay Lab, partnering with DLR’s Institute of Robotics and Mechatronics.

“With Floor Avatar we combining direct teleoperation method with supervised autonomy to regulate a number of robotic property to perform complex tasks: image a building site on Earth, the place a crane would possibly work alongside a bulldozer or excavator to get a giant process carried out.

“What we wish to discover out with this testing is how the astronauts carry out in apply. What management mode do they select? Have they got situational awareness by seeing the world by way of the eyes of a number of robots? And what judgements they make of their head about act?”

The Floor Avatar take a look at state of affairs assumes the comparatively structured atmosphere of a planetary floor base, the place the robots already know work together with a number of the objects round them and the opposite robots in place. So, an augmented actuality show produces an inventory of choices for the controller to pick.

If the specified possibility shouldn’t be out there, then the astronaut switches to direct management, feeling exactly what the robotic arm experiences by way of a force-feedback management system, permitting a excessive degree of precision.

“We’re excited to be a step nearer to giving astronauts and specialists on Earth a variety of potentialities to command and handle groups of various robots in space,” says Principal Investigator Neal Y. Lii from the DLR Institute of Robotics and Mechatronics. “We can use our robots on the floor as their bodily avatars and clever co-workers to execute ever extra complicated duties.”

Thomas concurs, “This human-robot collaboration paves the best way for future missions and everlasting outposts on the moon and past.”
