Summary

A novel iCEM+TL framework addresses challenges in sample-efficient low-level motion planning for robotic manipulation tasks. It tackles the growing complexity and long training times of existing models, particularly the Sample-efficient Cross-Entropy Method (iCEM)'s limitations in complex scenarios like stacking, sliding, and shelf placement. The framework explicitly integrates Transfer Learning (TL) to guide complex downstream tasks by transferring key iCEM parameters from simpler upstream tasks. Additionally, Reward Redesign (RR) through task decomposition optimizes performance for specific tasks. Simulation results show success rate improvements of up to 23%, with practical validation on a real Franka Emika robot in a stacking task.

Key takeaway

For Robotics Engineers deploying sophisticated manipulation systems, this framework offers a clear path to overcome training complexity. You should consider integrating the iCEM+TL approach, leveraging transfer learning and reward redesign, to achieve up to 23% higher success rates in tasks like stacking and shelf placement, thereby accelerating real-world deployment.
