See a shape-shifting robot Prol The Big, Bad World


Of course, evolution is invented That mammals climb 200 feet above the air Giant flaps of skin And 3-foot-wide crab That tree has grown, But has it ever invented a four-limbed animal with a telescoping organ? It doesn’t have to. Biology really can’t work that way. But robots can, of course.

Dynamic robot, aka DRET, for embedded testing The fly changes the length of his legsHumans not to protect humans, but to help robots of all stripes not read so much. Writing Today In the journal Nature is machine intelligenceResearchers in Norway and Australia describe how they got diuretics to learn how to lengthen or shorten its limbs to deal with different types of terrain. They then loosened the real-time moving robot in the real world, using that training to efficiently navigate surfaces that had never been seen before. (I.e. it was not able to break a pile))

“We can actually take the robot, bring it out and it can just start adaptation,” said Tonnes Niegard, a computer scientist at the University of Oslo and lead author of the paper, the Norwegian Defense Research Institute. “We saw that it was able to use prior knowledge.”

Walking animals do not have extensive organs because first and foremost, it is simply not biologically possible. However, this is not necessary. Thanks to millions of years of evolution, our bodies, humans, cheetahs and wolves are constantly scanning the ground in front of us for incredible agility, respecting obstacles.

Robots, on the other hand, need some help. Even a very sophisticated machine like Boston Dynamics Robot dog spot There are problems navigating complex areas. The robots improve their durability by being given both telescopic legs as they move over different surfaces and increase their energy efficiency. Stumbling around consumes a lot of battery power and a flying robot can hurt itself or people nearby. “I think it’s a good idea to have a body that’s sunny,” said Francisco Valero-Cuvas, an engineer at the University of Southern California. Who is the developer of the four-way robot However this was not involved in the new study. “What is happening here. A protected body makes a more versatile robot. “

Niegard and his colleagues first literally defiled the DRET by making it experimental sandboxes. In the lab, they filled long boxes with concrete, gravel and sand, representing different regions that the bot could find in the real world. Concrete is the simplest one – great and flat and predictable. Putting feet in the sand is even more uncertain, as the robot’s feet would sink in a unique way with each step. Concrete is a physically hard surface, similar to concrete, but it is also undesirable, because rocks can move, complicating the steps of the direc- tion. “There are examples of three terrains, with different hardness and roughness, you get quite a good representation of morphology or a kind of general interaction between body and environment,” Niegard said.
