Spurring the development of a ‘robot snake’ that moves with its body without wheels
After breaking through the rough terrain, enter the Enceladus subterranean sea
Verification of athletic ability until next year… Mounting of scientific equipment
On the surface of #Jupiter’s moon ‘Europa’, the expedition members stare out the window of the spaceship where they are staying with a firm expression. What they are looking at is a fellow member of the crew who started an outdoor investigation alone outside the spaceship a while ago. In the absence of information regarding the unfamiliar celestial body, Europa, field investigations are inevitably risky. Because of this, he went into a state of hyper-tension.
However, the hearts of the members who have stepped onto the surface of Europa are filled with the joy of stepping into a new world rather than worrying regarding their own safety. He hastily scoops the crushed ice and puts it in a cylinder slightly larger than a film canister. Then he puts the biomass sensor on the bowl.
After a while, a wonderful message pops up on the sensor that a single-celled organism similar to algae has been identified. This is the moment when life was first identified outside the Earth. All members of the expedition team are excited regarding the discovery that changed the history of mankind.
At that moment, something wriggles in the ice under the feet of the team member who was conducting an outdoor investigation. The ice breaks in an instant without a chance to recognize the identity, and the crew is sucked into the sea under the ice.
Sci-fi film released in 2013 <유로파 리포트>is a scene from Europa is a real moon of Jupiter. The space science community believes that there may be an underground ocean on Europa, where the surface is covered with ice. In particular, it does not rule out the possibility of life living in the sea.
It contains interesting content <유로파 리포트>There is one questionable passage in the line. The point is that a person willingly took part in an outdoor investigation, not knowing what dangers might arise. At the level of science and technology to send a manned probe to Europa, it is natural to send robots ahead of humans.
Total length 4m… jointed torso
Recently, researchers at the Jet Propulsion Laboratory (JPL) of the National Aeronautics and Space Administration (NASA) announced through official data that they are indeed developing robots that will operate on other celestial bodies. The place where this robot named ‘EELS’ will be put is the Saturn moon ‘Enceladus’. Like Europa, Enceladus is a celestial body that is assumed to have an ice-covered surface and an underground ocean inside.
The most striking thing regarding this robot is its appearance. In the video released by JPL on the Internet, the robot has a body with 10 short rods connected in a straight line like a train through joints. It is 4 m long and weighs 100 kg. It is a big and heavy ‘robot snake’.
According to JPL, the robot snake will break through obstacles on the ground and eventually enter the subterranean sea to swim.
The body of the robot snake has several spiral teeth. A total of 48 motors turn these cogs. With the rotational force generated at this time, the body rolls like a wrestler. You can also shake your body repeatedly while drawing the letter ‘S’ with your stomach on the floor. All of them are movements for movement on land or in the sea. Power comes from electricity.
On Enceladus, there is a geyser where water vapor from the sea erupts out of the icy crust, and the robot snake will use this as an entrance to enter the sea. The ultimate goal is the search for marine life.
Autonomous operation without remote control… equipped with lidar
Robot snakes operate autonomously without remote control by humans. The reason is the distance. Earth and Enceladus are regarding 1.2 billion kilometers apart. It takes a total of two hours at the shortest time for the district control center to emit radio waves to issue work orders and receive a report on whether or not the instructions have been followed. The situation is different from the moon, which can communicate with the earth in a few seconds. This means that at the Enceladus exploration site, it is much better for the robot to decide the direction to move on its own and solve it on its own even if it encounters difficulties.
To this end, the robot snake has a ‘Lida’. Lidar is a sensor that shoots lasers to find out the shape and location of objects in front. Recently, it is being installed in self-driving cars on Earth. The researchers plan to attach two or more cameras to the robot snake, giving it the ability to see objects in three dimensions. Here, a high-performance computer is also installed so that the robot snake can select an optimized movement path on its own.
The researchers built a prototype of the robot. Since last year, it has been test-driving in mountains full of snow and ice, flatlands where rocks and sand coexist, sheer cliffs, inside steep craters, and rugged lava caves.
JPL researcher Hiro Ono, who belongs to the research team, said through official NASA data, “There is a lot of information that can make a rover with four wheels.” I did my best to study,” he said. The research team plans to focus on maximizing the robot snake’s motor skills this year and next year. After that, it will work on selecting scientific equipment to be mounted on the robot snake.
