## 🛠️ Experienced Problems & Implemented Solutions

During the development of Team RCBC's vehicle, we encountered several key engineering challenges:

1. **Power Circuit Isolation Issue**:
   * **Problem**: The secondary voltage rail remained energized when the master switch was off, leading to standby battery discharge.
   * **Solution**: Remapped the LDO input lines directly behind the primary hardware switch, ensuring complete isolation when switched off.

2. **Sensor Field of View (FoV) Interference**:
   * **Problem**: Ground plane reflection occurred due to low chassis clearance.
   * **Solution**: Added a physical upward angle bias to the sensor mounts to optimize detection range up to 300 cm.

3. **Color Space Lighting Sensitivity**:
   * **Problem**: Fluctuations in ambient venue lighting affected color detection stability.
   * **Solution**: Replaced standard RGB masking with HSV color space filtering and dynamic threshold calibration routines.
