# {{PROJECT_NAME}} - Localization Template
Grid-based robot localization with sensor fusion and fault tolerance.
**Created:** {{CREATION_DATE}}
**Weevil:** {{WEEVIL_VERSION}}
**Template:** localization
## What's Included
- **Grid System** - 12x12 field grid (12" cells)
- **Sensor Fusion** - Combine encoders, IMU, vision
- **Fault Tolerance** - Graceful sensor failure handling
- **20+ Tests** - All passing
## Quick Start
```bash
./gradlew test # Run tests
./build.sh # Build
./deploy.sh # Deploy
```
## Architecture
Field divided into 144 cells (12x12 grid):
- Cell (0,0) = Red backstage
- Cell (11,11) = Blue backstage
- Cell (6,6) = Center
Sensor fusion priority:
1. Vision (AprilTags) - ±2" accuracy
2. IMU + Odometry - ±4" accuracy
3. Odometry only - ±12" accuracy
