基于图像识别的物料分拣系统——机械臂设计与控制

Material Sorting System Based on ImageRecognition-Design and Control of ManipulatorAbstractIn the 21st century,science and technology is highly developed.In order to adaptto the trend of modern technology,this article designs a robotic arm for automaticmaterial sorting to match the material sorting system based on Matlab imagerecognition that we designed.This article takes these four degrees of freedommanipulators as the research object,conducts mechanical mechanism design,staticanalysis,and uses SolidWorks Simulation to perform finite element analysis to verifythe feasibility of the manipulators,and then uses the Arduino development board tocontrol The servo is to send a series of pulses through the signal line,and change thepulse width to change the rotation angle of the servo,so as to realize differentmovements of the mechanical arm.Finally,the servo is simulated based on Proteussoftware to obtain the simulated pulse width.The overall workflow of sorting is to use Matlab for image recognition,detectthe type of the material,and then output the coordinates and data to Arduino,write aprogram in Arduino in advance,generate pulses to control the steering gear to rotate,thus completing the entire robot arm to the material Sorting action.Keywords:SolidWorks finite element analysis;Arduino control system;PWNpulse;steering gear;Proteus simulation
