On December 26, a research team led by Professor Wie Jeong-jae of the Department of Organic and Nano Engineering at Hanyang University announced that it developed 한글지원 해와 토토사이트 microrobot swarms for versatile task execution.

Swarm robotics is drawing attention as a technology that executes complex missions through swarm intelligence and the collective behaviors of multiple robots. The swarm intelligence can be expanded through sensor-based wireless communication like a formation flight of drones. However, microbots have limits in swarm control due to size, battery, and sensors. To solve this, microbots should be able to interact with others without traditional sensors and should be able to overcome environments with small kinetic energy.

Professor Wie Jeong-jae's team proposed an innovative solution to overcome these limitations by utilizing magnetic interactions between robots. The research team developed a technology to mass-produce rectangular cuboid shaped microrobots with magnetic anisotropy and designed their magnetization profiles to enable the microrobots to form unique structures. Through this approach, the robots could execute various tasks while maintaining their structures against external forces.

Through 한글지원 해와 토토사이트 combinations, the microrobots were autonomously assembled into various structures such as high aspect ratios, high packing densities, and high assembly stiffness, exhibiting functions tailored to different task environments. High-aspect-ratio structures proved efficient in overcoming obstacles, while high-packing-density structures excelled in underwater and terrestrial cargo transport. In addition, structures with high assembly stiffness showed exceptional performance in tasks like liquid metal shape transformation and vascular blockage removal.

Mass production of 한글지원 해와 토토사이트 robotic swarms maximized time and cost efficiency by designing 한글지원 해와 토토사이트 profiles and by simultaneously manufacturing hundreds of identical microrobots using a single microarray mold, and the 한글지원 해와 토토사이트 robotic swarms autonomously organized through external 한글지원 해와 토토사이트 field interactions, thereby, allowing them to perform multiple tasks.

"I am delighted to see the culmination of the students' long-standing efforts in this paper," said Professor Wie. "I hope that we continue to advance until microrobots are used in real-world applications in the future."

The findings of the research, supported by the National Research Foundation of Korea and AOARD, were published on December 18, 2024, in the prestigious international journal Device of Cell Press. The paper, titled 한글지원 해와 토토사이트 Swarm Intelligence of Mass-Produced, Programmable Microrobot Assemblies for Versatile Task Execution, was authored by Yang Ki-jun, a student of the Master-Doctorate integrated course at the Department of Organic and Nano Engineering at 한글지원 해와 토토사이트 University and co-authored by Doctor Won Su-kyoung, with Professor Wie Jeong-jae as the corresponding author.
