Abstract: | Nanomachines are controllable machines at the nano meter or molecular scale that are composed of nano-scale components. They have their own mechanochemistry, dynamics, workspace, and usability and are composed of natures building blocks: namely proteins, DNA, and other compounds. Some bacteria (i. e. Escherichia coli) swim by rotating helical flagella. The structure and motion character of the flagellum are introduced. Through the study, a micro-robot was designed and its mechanical structure was explained in this paper. In the future, the bionic micro-robot is expected tobe built, which can travel inside the human body and carry out a host of complex operations such as minimally invasive surgery, highly localized drug delivery, and screening for diseases that are in their very early stages. It is important to medicine and could be applied in other areas, including space exploration, electronics and military. |
