Demanding of the clinical laboratory instruments tending to be miniaturization and intellectualization,a new 3D automatic sampling system which occupied the instruments' small space and could directly sample on the standard sample plate was designed.A precise positioning algorithm which was suitable for the automatic sampling system was built according to the relevant principles of geometry and kinematics.For further reducing the positioning error of the system,the number of drive pulses was calculated by the accumulator iterative algorithm.Based on the VS 2010 platform,the system's operating software was developed by using the multi-threading technology.The results show that the system can quickly and accurately complete the sampling of the standard sample plate,and meet the need for miniaturization of the clinical testing equipments.The automatic sampling system may have a great market prospects.
