Visual Control of an Automatic Manipulation System by Microscope and Pneumatic Actuator

This paper presents an automatic manipulation system consisting of microscope and pneumatic actuator. Through image captured by microscope with a CCD camera, the position between the probe and the object can be calculated in the image plane. A visual fuzzy controller is designed to improve the precision of a nonlinear pneumatic manipulator. From the experimental results, the position error of the system is below 1 pixel. The system can be applied to puncture fish embryo.
