In the 1991 film “Terminator 2: Judgment Day” Cyborg T-1000 lures to go through metal rods. The other day, this science fiction scene was recreated with a real robot. The video below shows how a robot locked in a cage melts almost in a liquid and is easy to slip through narrow rods. Then it restores its original form again.
Researchers of the Chinese University of Hong Kong created a fundamentally new material. To do this, they introduced magnetic particles in gallium, metal with a very low melting point (about 30 ° C). The resulting material is planned to be used in medicine. For example, send it to a specific part of the human body to deliver medicines or removal from there foreign objects.
Engineers say that their “robot” is not only capable of changing shape, it has magnetic properties, and can also conduct electricity. “He is very flexible, but so far weak, and his movements are difficult to control,” the researchers say.
“Switching between liquid and solid states gives such robots to live functionality,” one of the researchers added. According to scientists, magnetic particles located in the robot allow you to remove it remotely using magnetic induction, as well as control the direction of its movement.
Senior researcher, Professor Karmeel Majidi, said new material can also boast of an extremely fluid liquid phase compared to other materials that can change their aggregate state. “Liquid phases of other similar materials are much more viscous,” said the researcher.
Before exploring the potential areas of application, the team tested the mobility and strength of the material in various scenarios. With the help of a magnetic field, robots jumped over the ditches, climbed the walls and even divided in half to move small objects together.
Professor Majidi added: “Further research will show how these robots can be used in the biomedical context. What we show now are just one -time demonstrations, evidence of the concept. But it will take much more research to understand how robots will be understood as robots This can be used in practice. “
Innovative development can also be used in other areas in addition to medicine. For example, for repairing wireless schemes or as a universal mechanical “screw” for assembling parts in hard -to -reach places.
