Ing, planing, grinding, drilling, and so on. However, since the full size or feature size of microrobots has reached the micro-nano level, these classic mechanical manufacturing approaches are no longer suitable for micro- and nanorobots. Consequently, some new processing approaches for micro- and nanorobot fabrication have already been developed in current decades, which include MEMS etching [5,6], deposition [7], 3D printing [80], laser cutting [113], pop-up process [148], and so on. Three-dimensional (3D) printing is one of the most promising processing techniques. This technique can speedily process complex microstructures, but because of Orexin A Agonist technical limitations, printing supplies are limited, structural strength is fragile, and manufacturing efficiency is low. MEMS etching and deposition technologies can process micro-nanoscale structures with higher processing accuracy, that will be helpful in the future for nanorobot structures. Having said that, additionally, it faced a variety of challenges, like fragile silicon-based components, stringent processing situations, and higher processing expenses. The major application of ultraviolet laser cutting is in the 2D processing of thin-layer supplies.
