Researchers at Huawei Noah's Ark London, Czech Technical University in Prague, and Imperial College London developed CLIER, a neuro-symbolic framework enabling robots to execute complex, long-horizon manipulation tasks by integrating visual and non-visual (e.g., weight, stiffness) perception. The system demonstrated overall success rates of 76.7% in simulated YCB-VRB and 64.4% in real-world YCB-VRB experiments, leveraging continuous feedback to recover from execution failures.
Key insights
- Closed-loop reasoning, with continuous scene re-evaluation and plan adjustment, significantly enhances robustness against execution failures and environmental uncertainties in robotic manipulation.
- Integrating active measurement of non-visual object properties into the scene graph enables robots to perform complex tasks requiring comparative physical reasoning, expanding beyond visual-only perception.
- The neuro-symbolic architecture effectively combines the pattern recognition capabilities of neural networks for perception with the structured, logical planning of symbolic execution, facilitating long-horizon task completion from natural language.
