The School of Engineering at Seoul National University in South Korea has announced a major breakthrough: the successful development of a next-generation liquid based soft robot. This innovative technology mimics the characteristics of living biological cells, such as the ability to transform, separate, fuse, and capture foreign substances. The relevant results were published in the latest issue of the journal Science Advances. Traditional solid based robots have limitations in simulating the flexibility and functionality of living cells, while this new type of particle armored liquid robot overcomes these challenges by wrapping an abnormally dense layer of hydrophobic (waterproof) particles. This design gives the robot both excellent liquid deformation ability and solid structural stability, allowing it to restore its original state without breaking even under extreme conditions. In the experiment, this robot demonstrated multiple functions, similar to the T-1000 robot in the movie Terminator 2. It can pass through metal barriers, capture and transport foreign objects; It can also integrate with other liquid robots and move freely on the water surface and ground. The research team has also developed a technology that uses ultrasound to control its movement speed, further expanding the application scope of robots. Due to its unique performance, this liquid robot is expected to be applied in multiple fields, including targeted drug delivery in the fields of biomedicine and soft robotics. In addition, given its ability to traverse extremely narrow spaces, the robot can also be used for tasks such as exploration, cleaning, chemical obstacle removal, and nutrient supply within complex machinery, rugged terrain, or disaster areas. This breakthrough sets new standards for the multifunctionality and adaptability of future robots. (New Society)
