Liquid Robot Developed in South Korea

A 'liquid robot' has been developed in South Korea, capable of changing shape and passing through grids - just like the T-1000 from 'Terminator'. Its body is composed of a special liquid with a protective coating, allowing it to maintain hardness, move on water, and even capture small objects, with control achieved through ultrasonic waves. In the future, it is intended to be used for drug delivery within the body and the exploration of hard-to-reach places.
