Because the sample transferring action of this system has no need to real time tracking, the target is consistent and only insure that sample can be transferred back to position only. The servo steering gear consists of the following parts: tiller, reducing gear set, position feedback potentiometer, DC electric generator, and control circuit. The working procedure are sending position information to signal control chip after every fluid flowed out, comparing to standard potential after obtaining DC skewing potential, outputting after obtaining voltage difference and outputting charge of voltage to motion ship to determine the rotation. The constant revolution of generator, rotation of potentiameter of connected reducing gear, and controlling speed and angle by PWM signal by servo steering gear, are designed to goal the easy control, high accuracy and high speed.
