MIT研发的柔性机器鱼与真正的鱼群融为一体_我的网站

A |     尽管水下机器人并不是新产品，但CSAIL团队表示，这些机器人通常被束缚在船只上。被称为SoFi的柔性机器鱼采取了一种不同的方法。其外部由硅橡胶和柔性塑料制成，里面是一个普通的锂聚合物智能电池，为电机提供动力，该电机将水泵入两个像气缸一样工作的气室，就像发动机中的活塞一样。

(Xinhua/Fang Zhe)The Shanghai Science and Technology Museum welcomed its 100 millionth visitor on Tuesday, as a growing number of travelers are looking to make science and technology a part of their holidays.
Zhang Zhiheng, a boy from east China's Shandong Province, was the landmark visitor. He visited the museum with his parents on the second day of his first trip to Shanghai.
Since opening its doors to the public in late 2001, the museum has grown into one of China's most popular science and education destinations. Through a wide range of science and technology activities and programs, it remains dedicated to boosting public scientific literacy and sparking curiosity in visitors of all ages.
After being closed for over two years for upgrading, the museum reopened early this year. It now also includes two branches: the Shanghai Natural History Museum and the Shanghai Astronomy Museum.
Back in 2001, the proportion of Chinese citizens with scientific literacy was only 1.4 percent, and the figure had risen to 16.74 percent by 2025, according to official data.
As public interest in science has grown, visits to science and technology museums have increasingly become part of everyday life.
For many families, museums have become a popular destination during holidays and weekends, offering children opportunities to expand their knowledge and broaden their horizons.
"The biggest change I feel during my museum visits is that science and technology keep advancing," said Zheng Qina, a post‑90s visitor from Shanghai. She was nine years old when she visited the museum in 2001. Today, her five‑year‑old son is also a regular visitor.
The trend is also extending to international travelers. With China's inbound tourism gaining momentum following eased visa policies, science museums have emerged as an increasingly popular destination for overseas visitors seeking a closer look at the country's technological development.
From January to July this year, the Shanghai Science and Technology Museum and its two branches received nearly 200,000 foreign visitors, accounting for nearly 5 percent of the total visitor numbers.
Francisco and his parents, a family from Italy, were among the visitors on Tuesday. After touring an exhibition on green energy, Francisco said he was deeply impressed by displays showcasing China's nuclear and hydrogen energy technologies.
In recent years, China has made major advances in fields ranging from artificial intelligence and humanoid robots to quantum science, green energy, space technology, life sciences and physical sciences. Science and technology museums offer visitors an opportunity to explore some of these developments through exhibitions and interactive experiences.
For Ni Minjing, director of the Shanghai Science and Technology Museum, a notable change among visitors is that they have shifted from passive recipients of knowledge to more active explorers of science.
"Teenagers in particular now have abundant channels to acquire knowledge. The role of science and technology museums can no longer be merely about resolving doubts," Ni said. "Instead, through diverse forms of science popularization, museums should inspire visitors, especially young people, to think and create."
"We will continue to innovate the way we popularize science, enrich science-related content, promote the spirit of scientists and foster a culture of innovation, so as to spark young people's curiosity, imagination and desire to explore," Ni added.

。为了让SoFi能够在不同深度游泳，该团队在每侧安装了两个鳍状物。

B | 它们配合可调整的重量舱和浮力控制单元，从而改变机器人在水中的垂直位置。虽然没有提到SoFi影响鱼类行为的潜力，但其柔性材料和安静的前行方式使得SoFi非常适合观察鱼类和其他海洋生物，但不会造成干扰。该团队在斐济的Rainbow Reef进行测试，使用防水的超级任天堂控制器和车载感应传感器引导其穿过水面，并使用车载摄像头拍摄高分辨率图像和环境视频。“据我们所知，这是第一种可长时间不受限制地在三维空间中游泳的机器鱼，”CSAIL博士候选人Robert Katzschmann表示。“我们很高兴能够使用像这样的系统来接近海洋生物，而不是人类可以靠自己获得的东西。”该团队希望继续改进SoFi，让它能更快速地在水中前行，甚至能够自动追踪真正的鱼类。“我们认为SoFi是开发水下观测台的第一步，”CSAIL主管Daniela Rus表示。“它有可能成为海洋探索的新型工具，并为揭开海洋生物的奥秘开辟新的途径。”描述SoFi的研究论文发表在《科学·机器人学》杂志上。
