Report summary:
Micro-robots, as large as a few millimeters and as small as a few microns, can easily operate in complex and tight spaces. Micro-robots with good biocompatibility and soft material texture for multimodal intelligent movements have great application potential in bioengineering and in vivo targeted therapy. The existing magnetic driven micro-robots still remain in simple drive control, and it is a great challenge to achieve precise motion control to solve practical problems. The report will focus on the motion control of soft film micro-robot, and introduce the visual servo 3D path tracking control of the magnetic driven soft film micro-robot, as well as the multi-modal motion mechanism for complex environment. It is a big challenge for micro-robots to make different motions and work together in the same external magnetic field. The anisotropic nature of a single micro-robot is the key to controlling the motion of multiple micro-robots in the same magnetic field. Based on the study of magnetization direction and motion efficiency of soft robots, the heterogeneous magnetization direction of thin-film robots is designed to control the speed difference of different micro-robots to achieve cooperative control. The final realization of independent position control of four soft film micro-robots and independent path control of three micro-robots provides a theoretical basis and technical basis for the synergistic targeting of soft film micro-robots in living organisms.
