Whatever the terrain, this quadrupedal robot adapts its gait on its own so as not to fall and that’s a real feat. It can run up to 11 km/h on sand.
The versatility and abilities of a robot in gymnastics atlas From Boston Dynamics impresses and his videos systematically stir up buzz. The robot can flexibly jump, perform somersaults and other stunts, but it is uncertain whether Atlas will be able to walk in sand without getting caught. Evolution on uneven terrain, especially sandy, remains an achievement for the robot. A team of researchers from the Department of Mechanical Engineering at the Korea Higher Institute of Science and Technology Kaist in South Korea worked on this topic.
The scientists began by modeling the stresses exerted by walking in sandsand, before experimenting with a quadrupedal robot called RaiBo. What is normal for us requires collecting a lot of data and having controllers that allow us to instantly adjust the approach according to the detected limitations. Thus, for a robot, when its paw lands on a sandy surface, the artificial intelligence (AI) has to predict the depth and SpeedSpeed that you are drowning in so that you can immediately make up for a movementa movement. To achieve this, the DesignDesign The initial should be very close to the real ground. This eq proprioception He was also allowed to stand up and turn over a mattress pneumaticpneumatic.
Picture the robot spinning on an air mattress. The tetrapod had to rely on its network of artificial neurons to interpret the nature of the surface and adapt speed by making decisions in real time. © KAIST
Race at 11 km/h on the sand
In practice, it is learning This then made it possible to strengthen the robot’s analysis and interaction capabilities on the different terrain surfaces it practiced. Ultimately, it can evolve steadily by adapting to the characteristics of the Earth without having to revise its control algorithm. In other words, the AI reinforced its own learning by training itself to improvise in order to be able to walk in a stable manner, whatever the terrain. Even better, the robot was able to move at 11 km/h on a sandy beach. The results of these experiments were published in the journal Robotics science.
