QERRA-v2 Classical — Call for Early Testers (ROS 2 Ethical Layer for Humanoid Robots)

Hi everyone,

I’m Marussa Metocharaki, working solo on QERRA-v2 Classical — a 100% classical and fully explainable ethical evaluation engine based on the SEMEV-12 framework (12 immutable human-centred vectors).

The long-term goal is to create a lightweight, auditable ethical safety layer that can run as a Condition node in Behavior Trees for robots, especially humanoid systems that interact with humans.

Current status:

  • Live public API on Hugging Face

  • Stable v1.8.1 core with improved nuance handling (moral pressure + strong commitment cases)

  • ROS2 bridge stub included (works standalone, becomes full node with rclpy)

  • All regression tests passing

I am now looking for a small number of serious early testers, especially from the ROS 2 and robotics community.

What would be most helpful:

  • Robotics scenarios with conflicting human instructions or high-stakes decisions

  • Medical, caregiving, or industrial ethical dilemmas

  • Any prompts where you think the score or reasoning feels wrong

Live API (free, demo key available): https://qerra-v2-api-classical-qerra-v2-api-classical.hf.space/docs

If you’re interested, please reply here or email me at marunigno@gmail.com with subject “QERRA Tester” and a short note about your background.

All honest feedback is extremely valuable at this stage.

Thank you!

Best regards,

Marussa Metocharaki
