五、(2025·绍兴模拟)阅读理解。〔人与社会——科学与技术〕
When you think of a robot,you might picture something with a lot of sensors(传感器)and hard metal arms controlled by a computer. But scientists at the AMOLF in the Netherlands have come up with a robot that has no brain and no sensors. And yet this robot can “walk” by itself. And if it’s dropped into water,it swims.
How is this possible? The team behind the robot says the secret is in the science of how air moves. If you have ever seen a “tube dancer” swinging,then you’ve seen the science that makes this robot work. Tube dancers are tall thin tubes of cloth that air is pumped(用泵抽送)through. High pressure from the pumped air fills the tube,making it stand up.
As the air flows through faster,the pressure drops. This drop in pressure forms a “kink(扭结)” in the tube,causing part of it to fall. The kink makes the pumped air move more slowly,raising the pressure again. The pumped air pushes the kink up until the dancer stands up once more. Air pressure moving a kink along a tube is exactly what drives the robot.
There are several remarkable things about the robot. One is its speed. The robot can cover a distance about thirty times its body length in a second. The robot can also adjust by itself to different conditions. If it bumps into a wall,it turns at once. Perhaps the most surprising thing is the fact that if the robot is dropped into water,it begins moving in a new way that allows it to swim.
At present,almost all of the robot’s skills are things that it just does itself. The researchers say that in the future they hope to develop new ways to control the robot and perhaps give it more skills.
