Vision-based method for precise manipulation of magnetic spiral microrobots

Microrobot is a kind of micro-and nano-scale robot. It has a wide range of applications in food detection with its characteristics of the minuscule structure, precise manipulation, and functionalization. There are certain differences in the helix number and scale of the magnetic spiral microrobot, which makes it difficult to achieve precise manipulation. To solve this problem, the precise manipulation of the magnetic microrobot is finally achieved by rational planning of the path of the microrobot, visual recognition, and motion control of the microrobot. This manipulation method provided powerful support for the use of microrobots for the sorting and detection of biological organisms. Moreover, this method can also be used for different types of microrobots which makes microrobots promising for food detection.
