Here we demonstrate that torons can be propelled by modulated electric fields and magnetically steered with full directional control, thus achieving programmable trajectories without net liquid flow. Within microfluidic architectures, we guide ensembles of torons through confined channels and realize targeted pick\u2010up, transport, and release of colloidal cargo. By combining experiments and numerical simulations, we uncover how magnetic alignment reshapes toron structure, speed, and stability, while confinement within microchannels gives rise to novel transport regimes. Unlike conventional colloidal inclusions, torons are intrinsically uniform, soft, and reconfigurable, establishing them as both an ideal model system for studying emergent phenomena in active topological matter and a versatile platform for next\u2010generation soft robots, adaptive delivery systems, and smart active\u00a0matter.<\/jats:p>","DOI":"10.1002\/smll.202511651","type":"journal-article","created":{"date-parts":[[2026,5,14]],"date-time":"2026-05-14T09:32:58Z","timestamp":1778751178000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Soft Colloidal Robots: Magnetically Guided Liquid Crystal Torons for Targeted Micro\u2010Cargo Delivery"],"prefix":"10.1002","volume":"22","author":[{"given":"Joel","family":"Torres\u2010Andr\u00e9s","sequence":"first","affiliation":[{"name":"Departament de Ci\u00e8ncia de Materials i Qu\u00edmica F\u00edsica Universitat de Barcelona Barcelona Catalonia Spain"},{"name":"Institute of Nanoscience and Nanotechnology IN2UB, Universitat de Barcelona Barcelona Catalonia Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rodrigo C.
