Abstract：To enhance the standardization of traditional Chinese medicine(TCM)acupuncture treatment by applying modern intel-ligent technologies,we developed a six-degree-of-freedom robotic arm system for acupoint positioning and manipulation.Firtly,the system combined the meridian theory of TCM,and realized acupoint recognition through RealSense depth camera and YOLOv8n-pose model.Secondly,the acupuncture manipulation simulation device was designed,the stepping motor and the lead screw slides were used to master the lifting-thrusting and twisting manipulation.Finally,the six-DOF robotic arm of myCobot 280 M5 was used,and the map-ping relationship between the coordinate system of the camera and that of the robotic arm through the nine-point calibration was estab-lished to realize the automated point searching.The accuracy test results showed that the average error of positioning was within 3 mm,the average deviation of lifting-thrusting amplitude was 2 mm,the twisting angle was negligible,and the average errors of the left and right arm point searching was 8.64 mm and 9.28 mm,respectively.In the stability test of the system,the overall success rate of the sys-tem reached 98.70%in 4 h of continuous operation.The system positioning accuracy,manipulation simulation accuracy,and system stability are good,can provide solutions for the modernization and intelligence of TCM acupuncture.
