Static Analysis of Picking Bionic Robot Arm Based on ANSYS Workbench

A picking robot is a standard agricultural robot. Agricultural picking operations are characterized by high labor demand and require a lot of physical strength and repetitive actions. Therefore, the development of picking robots has potential market demand and business opportunities, while factors such as robot cost, technical feasibility, and the ability to adapt to different crops and environments also need to be considered. Robotics is an important research area for bionic machines, and by combining the superior structure in biological systems with the properties of physics, humans may obtain bionic machines that are more complete in some properties than the systems formed in nature. Using Unigraphic software, a 3D model of the picking robot arm structure was created. Then, the model is imported into ANSYS Workbench, and modal and static analyses are performed on the model using finite element analysis methods. Thus, the robot arm structure is optimized and checked for feasibility. According to the results of the analysis, the equivalent stress and deformation distribution cloud diagram of the robot main structure model is obtained. Thus, the weaknesses of the bionic robot arm structure were identified and structural improvements were suggested. The results of the study provide a concrete basis for the rational design of the structural dimensions of the picking bionic robot arm.
