Abstract:The five degrees of freedom picking robotic arm was designed in this study.According to the requirements of the Target picking space for the picking robot, the size of the picking manipulator is optimized by the MATLAB optimization toolbox.Aiming at the lack of universality,a flexible and universal end effector that holds the fruit stems by pneumatic claws was designed.Using SolidWorks2015 to complete the 3D modeling and assembly of the mechanical arm and end effector. Through the research of the subject, the mechanical structure of the picking robot is optimized, the universality of the fruit and vegetable picking robot and the success rate of picking are improved. So as to realize the automation and intellectualization of fruit and vegetable picking.
Keywords:Picking robot arm MATLAB Optimization Toolbox End Effector 3D modeling
