🤖 AITL-H: Hybrid Structural Control Framework
⚠️ Note
The AITL-H project is currently in the conceptual and testing stage.
- Stability and response design rely on control theory (e.g., PID) as a prerequisite.
- FSM and LLM are designed as outer supervisory / support layers, and are not part of the stability-guaranteed control loop.
- The contents are conceptual ideas and partial PoC implementations, and are subject to change as further testing and development progress.

🧭 Overview
| Item | Details |
|---|---|
| Name | AITL-H (Hybrid) |
| Objective | Establishing humanoid robot control methods using structural AI control |
| Core Principles | - FSM: instinctive behavior control via state transitions - PID: continuous control of physical quantities (angle, velocity) - LLM: intelligence through advanced decision-making, dialogue, and learning |
🧘 Three-Layer Architecture
| Layer | Function | Implementation |
|---|---|---|
| FSM Layer | Logic control based on state transitions | fsm_engine.py, fsm_state_def.yaml |
| PID Layer | Physical control of joints and motion quantities | pid_controller.py, pid_module.py |
| LLM Layer | Situation assessment, anomaly detection, language response | llm_interface.py, llm_logger.py |
Each layer is loosely coupled yet cooperative, allowing independent development and step-by-step integration.

🌏 Strategic Significance
AITL-H is not just a control architecture.
By integrating state feedback control and state transition control, and combining with LLMs and SystemDK, it achieves real-time optimal design under physical constraints.
- Industrial impact
- 94% reduction in fault response time (PoC evaluation)
- 8× faster reconfiguration of production lines
- 40% reduction in design change costs
- National significance
- Securing competitiveness in advanced-node semiconductors and industrial autonomous systems
- Gaining leadership in international standardization
This technology must be integrated now.
SystemDK is not unique to AITL-H but is an essential foundational technology for all advanced-node semiconductor designs.
