In the future, will explore the Martian sands robotic snake
At its core, Mars is high, very high, I would say a giant desert. And what is most often found in the desert? Well, of course, the snakes! And since ” Kyuriositi “local monasteries, unfortunately (or fortunately), has not yet found, the European Space Agency is considering to bring back their own. However, while the unreal, and robotics. That’s why she was interested in the project SERPEX Norwegian company SINTEF, which she decided to finance it.
It should be noted that since the launch of Mars rover Sojourner, NASA literally had created a revolution in the study of global issues. The very first running on the Martian ground robots have been fixed. But over time, scientists realized that such an approach to the investigation may lead to the fact that the robot simply miss the moment when the Martian army amicable systems will pass by some of the mountain. In turn, the rovers can go to the site of the event itself, and the school subsequently decided to pass on to their shoulders. But after a while it became clear that the Martian surface for wheeled rovers was not so friendly. Dramatic evidence of this was that the rover NASA «Spirit” ended his career just stuck his wheels in a mound of soft sand, while being in the 48 million miles from the nearest tow truck.
But the snake, according to SINTEF, could feel himself perfectly moving on the Martian surface. Their ability to navigate through difficult terrain, sand, and the ability to penetrate through the tiniest places and slozhnodostupnye justifies the reason that mother nature has not endowed above average snake wheels. Realizing these benefits, a Norwegian research organization SINTEF in collaboration with the Center for interdisciplinary research space, as well as the Norwegian Space Centre suggest the use of robotic snakes as future researchers Martian sand prairies.
It is said that these robots create more than a dozen years. However, scientists still do not have the exact answer to that, as a technique of this design will behave under conditions of other planets and what tasks can be delegated to it.
The development team has several scenarios using its robotic snake. One of them can be used in the robot as an additional tool in conjunction with the autonomous some rover. When the rover gets to a certain place and can not explore the complex terrain, it releases a robotic snake and she has effortlessly due to its flexibility and, if I may say so, skill, reaches a place of interest to scientists. In addition, robotic snake is perfect for the tasks necessary for the collection of samples of soil scientists and their subsequent return to Earth.
But why only such uses? Why not just build a robot snake that would be explored Mars? The fact is that the rovers still have more advantages over robotic reptiles. As a tried and proven research platforms, they can be equipped with a mobile laboratory, to move faster on the relatively long distances and, most importantly, to bear the source of nuclear power. This, according to SINTEF, makes an excellent option rovers use as a base station for robotic snakes. In one scenario, such a robot can be operated as a highly flexible robotic arm. According to another – give yourself the opportunity, if necessary detach and crawl away from the rover to explore the area of interest to scientists. However, in this case, the robot will be attached to the rover cable, on which it will be supplied power and data transmitted by a team of engineers from the Earth. And if you do have cable and reinforced, the snake can be used as a kind of anchor the winch that will allow the rover to get out, if one somewhere, for example, in the sand, stuck.
The main question for scientists is currently a way to disconnect from the snake robot rover. After all, if he gets that opportunity, then we need some mechanism that will connect it back to the rover. While the design of this design is not all clear, but the European Space Agency intends to present its proposal on this issue in December.
One version of the robot snake SINTEF has already created. He called Wheeko and is designed to study the mechanisms of the robot on flat surfaces. Robot 10 is of identical modules of passive wheels which allow it to move over the surface. This snake robot can move not only forward, but as some representatives of these snakes, sideways and even backwards, but still fun to rear its head and impromptu smile for the camera. Ensure that you can just watch the video below.
Although this robot is far from representations in reality should look like Martian robozmeya, he even offers to get acquainted with some of the opportunities that a full robozmeya researcher will be able to provide in the future.
