To achieve the goal that robotic arms can follow targets accurately,this paper established a two-dimensional coordinate system for the arm model under which the movement of the arm was calculated,and the acceptable rotation angle of every joint of steering engine was worked out according to the coordinates of targets.By using this algorithm,a vision-based target following system composed of software and hardware together with a control system was designed,and a relevant experimental platform was set up.The camera was used to quickly identify and locate targets through the visual module of LabVIEW 2018 so as to obtain the coordinates.The rotation angle of every joint was then calculated by LabVIEW,and the steering engine of the joints was directed to move in a specific way through a control board,which ultimately enabled the robotic arms to follow the targets accurately.
