With the development of robotic technologies, robots that can move within our body and ensure that drugs are deposited at the right points or perform microsurgical operations have also entered our lives. However, these robots can still have some limitations and problems, especially in tight spots.
Scientists from Taiwan’s Soochow University have developed a new robot that can move and reach its target even in the tightest spots. Moreover, this robot was not a monolithic robot, but a liquid robot. Thanks to its liquid nature, the robot can change shape in tight spots and can even break into pieces.
Liquid robot that can be disassembled:
The robot you see above was made possible by magnetic ferro-fluids. Scientists used iron oxide nanoparticles suspended in oil to develop the robot. Besides these particles, the robot also includes a series of controllable magnets that act on the nanoparticles, directing the robot as needed and allowing it to change shape.
The robot, which is only one centimeter long, can reach dimensions much smaller than one centimeter thanks to this feature. Moreover, the robot can reach smaller robots in millimeter or micrometer sizes. These robots are driven by magnetic fields, so they can leave the main body and return.
On the other hand, according to scientists, although the robot is impressive, its use in the human body in the future seems far away for now. It is stated that the robot can be used in small areas where chemical processes such as virus tests are carried out rather than the human body. In this way, the robot can serve in the transport of chemicals necessary for reactions.
