In order to resolve the operation difficulty, high cost problems of traditional manual cell microinjection, a low-cost microinjection system based on hybrid-driven micro-robot is presented. System is mainly composed of microscope, 3-DOF(degrees of freedom) micro-robot, signal generator and power amplifier. Firstly, we describe the automated microinjection system. Secondly, we analyze the motion performance of the robot in the horizontal and vertical direction. The single step resolution is less than 5um each step working at a frequency more than 200Hz. Maximum range of vertical motion is 5mm and minimum resolution ups to 2um. Finally, shrimp egg microinjection experiment is conducted using our system. The experimental result shows that this proposed scheme is simple, reproducible and can achieve microinjection success rate of 88%. |
