基于51单片机的核酸采样机械臂设计
Design of Nucleic Acid Sampling Robot Arm Based on 51 Single-Chip Microcomputer

本文设计了一种基于51单片机的核酸采样机械臂运动控制系统，系统由机械臂模块、消杀模块、样本保存模块、语音引导模块和照明模块等5个模块组成，各模块之间相互配合，共同完成核酸采集与样品保存过程。控制思想是通过计算机语言来调节PWM输出占空比产生控制电压，由控制电压对机械臂的舵机进行控制，同时配合传感器最终实现在一定范围内对核酸被采样人员进行自动化核酸采集。
In this paper, a motion control system of nucleic acid sampling robot arm based on 51 microcon-troller is designed. The system consists of five modules, namely, robot arm module, kill module, sample preservation module, voice guidance module and lighting module. All modules cooperate with each other to complete the nucleic acid collection and sample preservation process. The con-trol idea is to generate control voltage by adjusting PWM output duty ratio through computer language, and control the steering gear of the robot arm by the control voltage. At the same time, the sensor is used to realize the automatic nucleic acid collection of nucleic acid sampling personnel within a certain range.
