Research on Automatic Nucleic Acid Throat Swab Collection System of Robotic Arm Based on YOLOv8
The traditional nucleic acid throat swab collection method is manually collected by medical staff,which consumes a lot of medical resources and has a high risk of infection.Most of the existing automatic robotic arm nucleic acid sampling systems use disposable bite devices to locate the mouth,but it is not flexible in actual use.In order to reduce the collection cost and the infection risk of medical staff,a robotic arm automatic nucleic acid throat swab collection system based on YOLOv8 is designed.This system adopts the YOLOv8 object detection algorithm for identification of pharyngeal region,and combines with a depth camera for pharyngeal 3D localization.When the collector enters the working space of the robotic arm,the visual servo system and the force control feedback system control the robotic arm to clamp the throat swab to complete the automatic collection of the pharyngeal nucleic acid throat swab.The experimental results show that this system has a high recognition rate of the pharyngeal region,and the force control feedback effect is good,which can meet the needs of field use.
