The project involves static analysis on the developed robotic arm. Increasing loads are applied to the robotic arm to determine the maximum load that it can hold. Firstly, the robotic arm model is created using CATIA. Then, it is analyzed using the generative structural analysis tool in the same software. Increasing loads are applied to the end of the robotic arm until significant deformation occurs. The same procedure is done for modified designs in the analysis software. The results considered include displacement and stress. Based on the results, the critical stress areas are near to the rotating joints of the robotic arm, the back of the gripper and the sharp edge of the second arm. Proposed modifications include increasing the servo motor shaft radius and edge filleting the affected area, increasing the thickness and reducing the length of the gripper base plate, and implementing a new design for the second arm.
