Improved PPO Optimization for Robotic Arm Grasping | Real-Robot Migration #Sciencefather



Introduction

Robotic arm trajectory planning has always faced critical challenges in unstructured environments, where randomness, uncertainty, and dynamic obstacles reduce the efficiency of traditional methods. This research introduces a novel hybrid reinforcement learning framework by combining simulated annealing (SA) with proximal policy optimization (PPO) to overcome local optimum traps, convergence issues, and limited adaptability. The proposed model provides a robust foundation for precise and collision-free grasping, thereby advancing the field of intelligent robotic manipulation in real-world industrial settings.

Research challenges

One of the main motivations behind this research is addressing the challenges of trajectory planning in unpredictable environments. Traditional reinforcement learning methods often struggle with local optimum traps and slow convergence, while real-time interaction in dynamic spaces remains difficult. By analyzing these limitations, the study emphasizes the necessity of a hybrid approach that enhances exploration without compromising convergence speed. This ensures the robotic arm can maintain stable performance in real industrial scenarios.

Methodological innovation

The study introduces three main methodological innovations to strengthen robotic adaptability. First, a probabilistically enhanced simulation environment was developed with a 20% obstacle generation rate to replicate dynamic real-world conditions. Second, the state-action space was optimized through a 12-dimensional environment coding and 6-DoF joint control, ensuring higher precision in decision-making. Finally, the integration of SA with PPO allowed dynamic adjustment of learning rates, balancing exploration and exploitation for better trajectory optimization.

Experimental validation

Extensive experiments were carried out to measure the performance of the proposed SA-PPO model against the baseline PPO algorithm. Results indicate a significant improvement with a 6.52% increase in task success rate, reaching 98% compared to 92% for PPO. Moreover, the SA-PPO framework reduced the number of steps required per grasping set by 7.14%, showing improved efficiency. These results highlight the effectiveness of integrating probabilistic simulation and hybrid learning for real-time adaptability.

Real-world deployment

The framework was tested on the AUBO-i5 robotic arm to validate real-world applicability. The transfer from simulation to actual machine performance demonstrated the robustness of the model, allowing the robotic arm to accurately grasp randomly appearing objects even in the presence of dynamic obstacles. This successful deployment provides evidence of reliable sim-to-real transfer, bridging the gap between controlled environments and industrial-scale applications.

Research impact

This work establishes a new paradigm in robotic arm trajectory planning by providing a scalable and adaptive reinforcement learning solution. The hybrid SA-PPO model enhances both reliability and efficiency in robotic manipulation, making it suitable for industrial applications that require quick decision-making in uncertain environments. By setting a benchmark for trajectory optimization, this research contributes to the broader advancement of autonomous robotics and intelligent manufacturing.
