▎ 摘　　要

NOVELTY - The system has a camera system connected to a control device that is connected to a six-degree-of-freedom mechanical arm. A flexible strain sensor i.e. resistance strain sensor, is fixed on a clamping end of a flexible end clamping device. The camera system collects a human face image of a subject, determines identity information of the subject according to the face image and a preset image database human face and sends the face image to the control device. The mechanical arm drives the clamping device to clamp the cotton swab according to a first control instruction and drives the cotton swab to the oral cavity of the subject according to a second control instruction such that the sampled cotton swab is driven to a sample placing position according to a third control instruction. The flexible strain sensor sends two flexible strain sensor signals to the control device, where the control device is provided with a Raspberry Pi. The strain sensor is made of graphene and silver nanowire. USE - Flexible sensing based intelligent unmanned nucleic acid sampling system for collecting cotton swab in an oral cavity during oral sampling of a subject. ADVANTAGE - The system effectively saves manpower, material resources, expandable nucleic acid detection covering surface and anthropomorphic operation, and satisfies the preset requirement. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of an intelligent unmanned nucleic acid sampling system. (Drawing includes non-English language text)
