Design Optimization and Rigid Body Dynamics of a Robot Arm using Advanced Simulation Tools

Abstract - Robotic arm design and optimisation are essential for improving performance, precision, and dependability in a variety of applications, including automation, medical robotics, and manufacturing. The objective of this project is to use sophisticated simulation tools, namely SolidWorks and ANSYS, to optimise the design and analyse the rigid body dynamics of a robotic arm. In order to obtain optimal performance while minimising wear, energy consumption, and mechanical failures, the study focusses on enhancing the mechanical design by optimising important factors such joint configurations, link lengths, and material qualities. While ANSYS is used to do thorough structural and dynamic simulations, evaluate stress, strain, and deformation, and examine the arm's behaviour under various loading circumstances, SolidWorks is used for 3D modelling. Through simulations, the dynamic performance—which includes the arm's motion, stability, and reaction to external forces—is examined, enabling the discovery of crucial design elements. The results of this investigation offer valuable perspectives for enhancing the design of the robotic arm, guaranteeing increased effectiveness, durability, and accuracy. The findings pave the way for the deployment of robotic systems in a variety of applications by advancing more dependable and effective robotic systems.
