【Tech 24H】Scientists at Chemnitz University of Technology in Germany have developed a type of distributed intelligent microrobot called "smartlets" that can communicate, respond to each other, and cooperate in water. This achievement is seen as a significant step forward for microrobot systems towards intelligent collaboration. In the future, they could potentially be used for tasks such as water quality monitoring, minimally invasive medical diagnosis, and exploration in confined environments. Furthermore, their ability to form interactive, stimulus-responsive clusters holds promise for applications in soft robots, autonomous inspection systems, and distributed sensor networks.
