Keywords: micromotors, soft microrobots, light-based control, photoresponsive materials Mobile microscale devices and microrobots can be powered by catalytic reactions (chemical micromotors) or by external fields. In this report, we focus on the role of light as a versatile means for wirelessly powering and controlling such microdevices. Recent advances in the development of autonomous micromotors are discussed, where light permits their actuation with unprecedented control and thereby enablesdoi:10.1002/adom.201900370 fatcat:zmd2wyeoi5fcpiv2gtp5gsr5fq
