Microrobots are poised to transform biomedicine by enabling precise, noninvasive procedures. However, current magnetic microrobots, composed of solid monolithic particles, present fundamental challenges in engineering intersubunit interactions, limiting their collective effectiveness navigating irregular biological terrains and confined spaces. To address this, we design hierarchically assembled microrobots with multiaxis mobility adaptability the potential interaction energy between subunits create stable, self-reconfigurable structures capable carrying protecting cargo internally. Using double emulsion templates control techniques, confine 10 nm iron oxide 15 silica nanoparticles within shell 100 μm microcapsules that form multiunit robotic collectives. Unexpectedly, find asymmetric localization enhances intercapsule energy, creating stable connections under rotating fields without altering susceptibility. These microcapsule collectives exhibit emergent behaviors, self-reconfiguring into kinematic chain-like traverse complex obstacles, arched confinements, adhesive, rugged tissues typically impede microscale systems. By harnessing these functions, demonstrate targeted antifungal delivery using a localized biofilm model on mucosal tissues, showing effective killing ofCandida binding or causing physical damage host cells. Our findings show how hierarchical assembly can produce cargo-carrying collective, self-adaptive for traversing environments, advancing biomedical applications.
