Abstract The flexible manipulation and directional transport of fluids, including droplets bubbles, are foundational to numerous applications. Fluid based on external field stimulation fixed structures has a wide range applications in both natural artificial materials, such as water collection, electrolysis, droplet energy medical diagnosis, etc. However, bubbles exhibit opposite wettability, the inherent opposition between hydrophilicity hydrophobicity presents significant challenge developing system capable manipulating bubbles. Here, inspired by multiple organisms, magnetic‐actuated Janus spherical robot with switchable wettability driving core or solid‐like slippery surface platform is proposed, which achieves dual programmable Furthermore, can achieve transition from superhydrophobic superhydrophilic within 8 min under UV light. It noteworthy that demonstrates superior capabilities speed carrier volume liquid (bubbles), reach 18 (13) cm s −1 800 (500) µL, respectively. This strategy provides novel reliable method for automated broadens their
