Abstract
The purpose of this study is development a blood collection assistant system for accident prevention. In the previous studies, a vein detection system by using absorbance of the hemoglobin and a needle puncture system by using the peak detection of puncture force and blood detection by electrode were developed and integrated. In this study, needle posture control following to arm posture was performed by using posture markers. As the results, the error of position adjustment was acceptable range. However the control of angle and direction was desired the improvement.
