The medical robot systems have the effect of reducing the work load and
preventing accidents by supporting task that are difficult for
inexperienced medical practitioners. Recently, research on automated
blood collection and injection robotic system has been increasing, but
work is still necessary such as replacing needle tips, setting
tourniquet and fixing the patient's arm. In this letter, we propose an
intelligent intravenous injection robot without having to see the
medical workers face-to-face. We design a revolving system for automatic
needle replacement and an arm holder for vessel fixation. Finally, we
experiment positioning the needle at the target point by position
control based on mathematical modeling and velocity kinematics.
