A hibernating robotic space arm wakes up to transport the object on the International Space Station

The new European robotic arm (era) by Europeans space The Agency (ESA) has completed its first transfer of an object following the orders of an astronaut on the International Space Station. Many tasks are performed automatically Robotic arms on the International Space Station. It can be directly controlled or pre-programmed to complete actions. There are two other robotic weapons aboard the International Space Station – the Canadarm2 and the Japanese Remote Experimental Module manipulator system.

Robotic arms from Canada and Japan were fully operational on the International Space Station, taking an active role in the docking of visiting vehicles, regular station maintenance checks, and closing external payloads. However, they couldn’t reach Russian orbital part of the station. Various shapes of base points and payload mounting units are contraindicated in other areas of the International Space Station. As a result, ERA entered the scene of the accident to serve the Russian segment. The European Robotic Arm (ERA) is the first robot to have the ability to “walk” around the Russian section of the International Space Station.

Teams in Moscow, Russia and the European Space Agency’s control room in the Netherlands monitored the movements of the ERA on August 24. During the first movement, the Russian cosmonauts woke the robotic arm from hibernation, stretched it, and carried a small suitcase-sized payload from one side. From the Nauka Lab Multipurpose Unit and reinstall it in its original position. ERA returned to hibernation after the operation, which took about six hours to complete. The trial showed that European robotic arm Payloads and their latch can be moved outside The Russian part of the International Space Station Accuracy of 5 mm. The human age is like a human arm in many ways. Elbows, shoulders, and wrists are all there and counted. The powerful 11-meter European robotic arm has a maximum load capacity of eight tons, and can withstand temperatures from -150 to 120 degrees Celsius.

Complete an unfinished task

On September 2, cosmonauts Oleg Artemyev, commander of Flight 67, and Denis Matveev, flight engineer, Spacewalking begins. The goal was to integrate the ERA into the Nauka Laboratory by gaining access to the airlock hatch in the mooring compartment of the Poisk. The ERA external control panel has been moved from one work area to another. The astronauts also tested a way to make the arm stiffer, so it would be easier to grab payloads.

The spacewalk completed previous spacewalk missions on August 17, which were shortened when Attimeev’s Orlan spacesuit displayed unusual battery readings a few hours after the extravehicular operation. Artemyev and Matveev installed a pair of cameras on the arm and removed the components from the ERA . end effector Before ending the spacewalk. Operations outside the space station will be examined with the help of these infrared cameras. Cosmonauts of the Russian part of the International Space Station will be able to save time and effort during the maintenance of the space station with the help of ERA.

In mid-September, ESA aerospace engineers will conduct a “performance mission” to test the arm’s capabilities to their limits. During the assignment, brake efficiency, joint motion, and arm strength control will be evaluated. Meanwhile, teams will be working on the ground as well Image quality and resolution analysis Captured by robotic arm cameras. These cameras on eraMy elbow will also be used to direct operations even during a tropical night.
