biomedical fields, such as medical diagnosis, nanoscale surgery, and targeted therapy. In this article, recent progress on micro/nanorobots is reviewed regarding actuation technologies. First, the different actuation mechanisms are divided into two types, externalfieldactuation and self-actuation. Then, a

Keywords: actuation methods; externalfieldactuation; micro/nanorobots; self-actuation; Introduction
In the past few decades, micro/nanorobots have developed rapidly as an emerging field of robotics. Macroscale robots are limited in their use in specific scenarios such as working in small spaces. In
and efficiently at the micro/nanoscale. According to the different actuation mechanisms, actuation technologies that have already been applied to micro/nanorobots can be summarized into two categories. One is externalfieldactuation, including external magnetic fields, electric fields, light fields
