This book provides a systematic and comprehensive overview of the design, fabrication, motion control, and future development of magnetically actuated soft microrobots. It is composed of six chapters that cover the fundamental principles, material strategies, and control technologies underlying the development of this emerging field. The first two chapters introduce the basic concepts, materials, and fabrication methods of magnetic soft microrobots. Chapters 3 to 5 focus on the locomotion mechanisms, motion control strategies, and cooperative control of multiple soft microrobots, presenting both theoretical analyses and experimental insights. The final chapter discusses the future trends in materials innovation, modeling, control algorithms, and biomedical applications. This book serves as a valuable reference for researchers and engineers working in microrobotics and biomedical engineering, as well as an informative guide for graduate students and educators interested in magnetic soft robotic systems.
