Evolving Skill Modules under a Fixed Planner: Versioning, Rollback, and Runtime Governance for Long-Lived Robot Systems
TL;DR
A framework for managing evolving skill modules in long-lived robot systems was developed, revealing significant instability in task success rates and issues with action governance. Key findings include a promotion gate that effectively filtered regressions, ensuring system reliability.
✦ Why It Matters
Implement a robust versioning and rollback strategy for skill modules in your robotic systems today.
Key Takeaways
- Monitor task success rates across multiple runs to ensure reliability.
- Implement a promotion gate to filter out regressions effectively.
- Consider the implications of whole-task policies versus phase decomposition.
- Utilize dip detectors to identify potential regressions in skill modules.
How It Works
The framework employs a fixed decision layer that dispatches versioned skill modules while a runtime layer screens actions to ensure compliance with performance standards. This dual-layer approach allows for continuous improvement of robot skills without compromising system integrity.
⚠ The Catch
Task success rates were found to be unstable, with significant variability across different random seeds, complicating the assessment of method effectiveness.
