Structure
1. Concept Map
The Concept Map represents the core logic of the Psychological Sand Table. It connects the psychological therapeutic theories with the interactive feedback loop of the hardware system. 
- Theory Integration: Mapping symbolic sandplay actions to emotional states.
- System Logic: How user input triggers mechanical and visual responses.
2. AI-generated Image (Conceptual Inspiration)
This section details the physical construction of the sand table, including mechanical components and assembly. 
3.1 Mechanical Architecture
A high-level view of the table's structural layers:
- Top Layer: The sand bed and miniature interaction area.
- Middle Layer: Sensor arrays (OAK Camera mounting) and actuation mechanisms.
- Base Layer: Housing for Arduino/ESP32 controllers and power supply.
3.2 Assembly & Exploded View
The 3D CAD models used for fabrication.
- Laser-cut Parts: Box structure and internal supports.
- 3D-printed Parts: Custom brackets for the OAK camera and servo mounts.
