4-RCRP并联机器人运动学分析与仿真 Introduction: Parallelrobotsaremachinesthatconsistofseverallinksthatareconnectedinparalleltoafixedbaseandend-effector.Theserobotsaredesignedtoofferhighprecision,stiffness,andaccuracybyusingtheprinciplesofparallelism.Inrecentyears,theuseofparallelrobotshasseenasignificantincreaseinvariousfieldssuchasaerospace,medical,andindustrialautomation.Oneofthemostcommonlyusedparallelrobotsisthe4-RCRPparallelrobot.The4-RCRPparallelrobotiswidelyusedduetoitshighload-bearingcapacity,highaccuracy,andhighcontrolability. Kinematicsof4-RCRPparallelrobot: Thekinematicsofarobotreferstothestudyofitsmotionandpositioninspace.Thekinematicsofa4-RCRPparallelrobotisrelativelysimple,anditsforwardandinversekinematicsolutionscanbeobtainedusingtheD-Hparametermethod.Thekinematicequationsofthe4-RCRPparallelrobotcanbederivedbyrepresentingeachlinkwithacoordinateframe,andthetransformationmatricescanbedeterminedusingtheD-Hparameters.Theforwardkinematicsolutioninvolvesdeterminingthepositionandorientationoftheend-effectorbasedontheinputvaluesofthejointangles,whiletheinversekinematicsolutioninvolvesfindingthejointanglesrequiredtoobtainaspecificpositionandorientationoftheend-effector.
