Researchers in South Korea have developed microrobot swarms mimicking the collaborative behavior of ants to perform tasks such as transporting objects and unclogging tubes. Published in the journal Device, this study highlights the robots’ ability to work together under rotating magnetic fields, tackling challenges beyond the capacity of individual robots. These microrobots possess potential medical applications, including minimally invasive procedures for clogged arteries and precise handling of biological samples.
The team, led by Jeong Jae Wie of Hanyang University, demonstrated the high adaptability and autonomy of microrobot swarms through various tests. For instance, a swarm managed to transport cargo weighing 350 times more than its individual members and successfully cleared obstructions resembling blocked blood vessels. Additionally, swarms comprised of 1,000 robots created a raft that floated and transported payloads significantly larger than themselves.
Unlike previous spherical designs, these cube-shaped microrobots feature stronger magnetic attractions due to their larger surface areas. While the prototypes show promise, further advancements in autonomy are necessary before real-world applications can be realized, as the swarms currently require external magnetic control to navigate. Future research aims to enhance their autonomous capabilities for complex environments.
