Abstract

Nasal swab was intensively performed by medical workers during the COVID-19 pandemic, which unfortunately increases their infection risks. To solve this problem, this study aims to developing a robot to perform nasal swab automatically. An admittance control strategy based on the tangent-normal-binormal (TNB) frame is proposed to on-line adjust the path of the robot according to the external force/moment feedback, and confine the contact force within a pre-specified bound. Therefore, safety and comfort of nasal swab are enhanced. Experiments are conducted on a curved passage and a dummy. Quantitative performance indices are defined to evaluate the effects of the control parameters. The results show that the robot can automatically adjust its path to pass the swab through the curved passage while restrict the contact force within the pre-specified bound, despite inappropriate initial poses. Besides, experiments on the dummy show promising results for practical applications of the proposed nasal swab robot.
