Optimizing Precision and Operational Efficiency in Object Manipulation: A Novel Algorithmic Paradigm for the UR-3 Robotic Arm Integrated with ROS Framework

Abstract

This research presents a sophisticated algorithmic framework designed to optimize pick-and-place operations using the UR-3 robotic arm within the Robot Operating System (ROS) architecture. The study addresses key challenges in robotic manipulation, such as achieving high-precision 3D pose planning, real-time object localization, and singularity avoidance. By integrating ArUco marker-based object recognition, the proposed method enhances the robot’s ability to accurately detect and manipulate objects in dynamic and unstructured environments. A meticulous approach is employed to fine-tune the parameters of the Open Motion Planning Library (OMPL) within ROS’s MoveIt framework, improving path planning efficiency and object handling.

The UR-3 robotic arm’s six degrees of freedom are leveraged to navigate complex spaces while avoiding obstacles and optimizing motion trajectories. Through advanced control strategies, the gripper system is calibrated to adapt to various object shapes, sizes, and weights, enhancing the overall reliability of the pick-and-place tasks. The algorithm also incorporates singularity detection and avoidance mechanisms, ensuring smooth and continuous motion during operations. Extensive experiments conducted in simulation environments such as Gazebo and RViz demonstrate significant improvements in both accuracy and speed.

Performance metrics including path optimality, computational efficiency, and task completion rates were measured, validating the system's robustness. Results show a marked increase in task efficiency, with enhanced adaptability to diverse object configurations and real-world constraints. This research contributes to the field of robotic manipulation by providing a comprehensive solution to optimize automated pick-and-place operations, offering potential applications in industrial automation and intelligent manufacturing.
