Development of a 4 DOF Robot Arm for Picking and Placing

Abstract

The article describes the design procedure and structural analysis of a robot arm model with four degrees of freedom capable of picking up and placing a 500-gram box-shaped object. The robot arm structure is based on the existing 4-degree-of-freedom robotic arms, then redesigned to meet the requirement and place objects in the Solidworks-designed project. The analysis of structure, stress, displacement, deformation, and safety factor is also performed. Utilize the Optimization tool in Solidworks to optimize the design of the end actuator of the robot arm. Finally, a robotic arm prototype proving the reliability of the analysis process has been presented.
