Wetlands play an important role in the ecosystem. However, about 35 per cent of the wetlands have been lost in the past 50 years, said the UN. Hoping to protect the wetlands, Cui Luoyao and Lyu Haoyan, two 14-year-old girls from Beijing created a mudskipper (弹涂鱼) amphibious robot (两栖机器人). They won the Gold Award of the 19th Soong Chingling Award for Children's Invention on August 17, 2024.
“Traditional robots faced problems in wetlands,” Cui said. As amphibious fish, mudskippers are small and can move freely in wetlands. Inspired (启发) by the little creatures, they added a special chest (胸腔) and tail fin (鳍) to their robot. The fin can help the robot move freely on land and swim underwater. They also learned coding to control (控制) the robot with their phones from far away, up to 300 metres. What's more, they put in different sensors (传感器) to see plants and check water quality.
But things didn't always go well. How to keep the main electronics (电子元件) dry when the robot went underwater was a big problem during testing. “The 3-D printed parts we used couldn't seal (密封) well,” Lyu said. After trying different ways, they found that placing rubber rings in the gaps (缝隙) worked well in stopping water from getting in.
After successfully controlling their robotic mudskipper on land and underwater, they were happy with their success. “I feel so proud because our robot can help look into the places that people cannot reach,” said Cui.

The Chinese crested tern (凤头燕鸥) is a type of seabird. The bird is about 30 - 40 cm long, with grey wings and a white body. 1. According to (根据) a report, there are only about 150 Chinese crested terns all over the world.
The first record of the bird was in 1861. 2. Scientists once believed that it may die out. Amazingly, over 60 years later, some birdwatchers saw some in Fujian and Zhejiang.
Scientists working in a nature reserve in Zhejiang wanted those birds to stay there. They built some artificial nests (人工鸟巢). They even put some hand-made birds of the same size as Chinese crested terns there. 3. More Chinese crested terns flew to the islands and laid their eggs.
Chinese crested terns lay eggs as the weather gets warmer. 4. During their stay in Zhejiang, volunteers from a Chinese crested tern protection group help with a lot of work. They record the information of every bird on the islands. They help them lay eggs safely. 5.
Hope there  will  be  more  and  more  Chinese  crested  terns  flying  in  the sky.
A.Everything went well.
B.Bird-lovers come here.
C.It lives in a very special way.
D.The number of the birds is very small.
E.However, after the 1940s, people couldn't find them.
F.When it gets cold, they fly to southern areas to spend the winter.
G. Also, the volunteers drive away dangerous animals like snakes and mice.
