Abstract Microrobots for endovascular embolization face challenges in precise delivery within dynamic blood vessels. Here, an intelligent generic high‐throughput oscillatory shear technology (iGHOST) is proposed to fabricate diversely programmable, multifunctional microrobots capable of real‐time visual guidance vivo embolization. Leveraging machine learning (ML), key synthesis parameters affecting the success and sphericity are identified. Therefore, ML‐optimized iGHOST enables continuous production uniform with programmable sizes (400−1000 µm) at ultrahigh rate exceeding 240 mL h −1 by segmenting fluid into droplets before ionic cross‐linking, without requiring purification. Particularly, iGHOST‐fabricated magnetically responsive lipiodol‐calcium alginate (MagLiCA) highly distinguishable under X‐ray imaging, which allows navigation flows up 4 min accurate liver kidney vessels, thus addressing current issues. Crucially, MagLiCA possess drug‐loading capabilities, enabling simultaneous site‐specific treatment. The process intelligent, rapid, green manufacturing method, can produce size‐controllable, potential drug treatment imaging across various medical applications.
