In this paper the Path of Nano robot in Human Carotid Artery Bifurcation has tracked with three different velocities by Nano robot. And the influence of Blood Flow with high Reynolds Number on the path of Nano robot has studied by the Finite volume method. The blood flow assumed laminar Newtonian flow and the Reynolds number assumed in the range of ۲۱۲۵- ۵۵۷۲. Based on the result of this studding the velocity of Nano robot can’t change the path and in arteries with high ReynoldsNumber the users cant choosing the path of Nano robots. So base on the result of this study controlling the path of Nano robots on artery that have high Reynolds number like aorta, femoral, carotid and etc is by the velocity of Nano robot is impossible.
