Abstract
This chapter reviews the key advancements and challenges of shape-programmable magnetic robots that are in the micro- to millimeter length scales. A critical advantage of these miniature soft robots is that they have significant potential to attain mechanical functionalities beyond those of their traditional rigid counterparts. As a result, shape-programmable magnetic miniature robots have shown great potential in revolutionizing a broad range of applications pertaining to biomedicine, bioengineering, and lab-on-chip technology. To have a comprehensive discussion, various aspects of these robots, including their theory, programming and fabrication methods, untethered locomotion, and mechanical functionalities are analyzed. It is envisioned that this chapter will be able to provide critical analyses, which can inspire scientists and engineers to make shape-programmable magnetic miniature robots significantly more dexterous and functional in the future.
