Swarms of tiny robots, no bigger than a grain of sand, are revolutionizing the world of robotics. These robots, guided by magnetic fields, can work together like ants. They can join forces to create floating rafts, lift objects much heavier than themselves, unblock blood vessels, and deliver drugs to specific areas inside the body.
Created by Jeong Jae Wie and his team at Hanyang University in South Korea, these cube-shaped robots are made from magnetic alloy embedded in epoxy resin. By exposing them to strong magnetic fields, the robots can be programmed to form different shapes and move in specific ways. This technology allows for the efficient production of hundreds to thousands of these microrobots, each designed for a particular task.
In experiments, the microrobot swarms showed impressive capabilities, such as climbing over obstacles and forming floating rafts. They even managed to transport a pill much heavier than themselves through liquid. While there are still challenges to overcome, experts like Xiaoguang Dong from Vanderbilt University believe these microrobots hold great promise for delivering drugs precisely and effectively to targeted areas in the body.
Despite safety concerns, the future looks bright for these tiny robots in the field of medicine, offering hope for more accurate and efficient treatments.
