德国工程师设计出可像水银一样变形的液态金属机器人
在慕尼黑郊外的一家机器人研发中心，德国工程师们展示了一种科幻般的成果——由镓基液态金属制成的小型机器人，它们可以像活体水银一样变形、分裂和重组。这些可变形机器人正被开发用于搜救和深度医疗领域。
每个机器人都能穿过狭窄的缝隙，伸展成细丝，或在几秒钟内重新组合成固体工具。这种变形是由精确的磁场触发的，磁场会重新排列金属分子。这些机器人可以携带微型传感器和摄像头，在碎片中穿行，甚至可以穿过受损的管道进行维修。
冷却时，金属会变硬，使机器人能够举起自身重量数倍的物体。加热时，它们会恢复液态，流过裂缝或从内部密封泄漏处。这种兼具灵活性和强度的特性，开创了自适应机器的新纪元。
研究人员正在测试这些机器人如何在人体内导航——例如，通过血液循环输送药物或清除阻塞物。早期模拟结果表明，它们能够到达传统仪器无法触及的地方。
对工程师而言，这不仅仅是机器人技术——它让我们得以窥见那些模糊了机器与生命、流体与形态界限的材料。
Germany engineers design liquid metal robots that change shape like mercury
In a robotics facility outside Munich, German engineers have unveiled something out of science fiction — small robots made from a gallium-based liquid metal that can morph, split, and reassemble like living mercury. These shapeshifting bots are being developed for search-and-rescue and deep medical use.
Each robot can pass through tight gaps, stretch into thin threads, or reform into solid tools within seconds. The transformation is triggered by precise magnetic fields that rearrange the metallic molecules. The bots can carry micro-sensors and cameras, navigating debris or even moving through damaged pipes to perform repairs.
When cooled, the metal stiffens, allowing the robots to lift objects several times their own weight. When warmed, they return to liquid, flowing through cracks or sealing leaks from within. The blend of flexibility and strength opens a new category of adaptive machines.
Researchers are testing how these robots could navigate inside the human body — traveling through the bloodstream to deliver medicine or remove blockages. Early simulations show they can reach places where traditional instruments fail.
For engineers, it’s more than robotics — it’s a glimpse into materials that blur the line between machines and life, between fluid and form.
