SmoothVLA: Aligning Vision-Language-Action Models with Physical Constraints via Intrinsic Smoothness Optimization
🤖AI Summary
Researchers introduce SmoothVLA, a new reinforcement learning framework that improves robot control by optimizing both task performance and motion smoothness. The system addresses the trade-off between stability and exploration in Vision-Language-Action models, achieving 13.8% better smoothness than standard RL methods.
Key Takeaways
- →SmoothVLA combines binary task rewards with continuous trajectory smoothness optimization for better robot control.
- →The framework uses intrinsic rewards computed directly from policy rollouts without requiring external environment feedback.
- →Testing on LIBERO benchmark shows 13.8% improvement in smoothness over standard reinforcement learning methods.
- →The approach bridges the gap between supervised fine-tuning's limited generalization and RL's erratic movement patterns.
- →Group Relative Policy Optimization (GRPO) is leveraged to establish trajectory smoothness as an explicit optimization prior.
