The provided text offers a comprehensive overview of magnetically steerable micro-robots, detailing their fundamental principles, enabling technologies, and diverse applications. It explains how these miniature devices overcome the unique challenges of micro-scale physics, like low Reynolds numbers, by leveraging external magnetic fields for precise control. The text categorizes fabrication methods as top-down (e.g., 3D laser lithography) or bottom-up (e.g., self-assembly of nanoparticles), and discusses the importance of biocompatible materials for in vivo use. Furthermore, it highlights key applications in biomedicine (targeted drug delivery, micro-surgery), environmental remediation, and micro-manufacturing, while also addressing critical challenges such as imaging, navigating complex physiological environments, and scalable production. Finally, the overview explores future directions, including the development of intelligent, collective micro-robotic systems augmented by artificial intelligence.
