Light‐driven micro/nanorobot (LMNR), as an artificial micro/nanomachine, manifests excellent controllability, and appealing applications. The development of light‐manipulation strategies significantly advance both single and swarming LMNR systems, improving their capability for sophisticated tasks. In this review, the existing manipulation strategies for LMNRs, which are categorized according to encoding methods of light signals, is summarized. On top of it, the swarming systems are overviewed by considering the field in charge. The emerging applications and major challenges of LMNRs are then presented and discussed, which may lend insight to researchers to develop bespoke LMNR systems for target applications.
