Implements comprehensive robot localization system as third template option.
Teams can now start with professional positioning and navigation code.
Template Features:
- 12x12 field grid system (12-inch cells)
- Multi-sensor fusion (encoders, IMU, vision)
- Kalman-filter-style sensor combination
- Fault-tolerant positioning (graceful degradation)
- 21 files, ~1,500 lines, 3 passing tests
Core Components:
- GridCell/Pose2D/FieldGrid - Coordinate system
- RobotLocalizer - Sensor fusion engine
- OdometryTracker - Dead reckoning from encoders
- ImuLocalizer - Heading from gyroscope
- VisionLocalizer - Position from AprilTags
Sensor Fusion Strategy:
Priority 1: Vision (AprilTags) → ±2" accuracy, 100% confidence
Priority 2: IMU + Odometry → ±4" accuracy, 70% confidence
Priority 3: Odometry only → ±12" accuracy, 40% confidence
System gracefully degrades when sensors fail, maintaining operation
even with partial sensor availability.
Hardware Abstraction:
- Interfaces (Encoder, GyroSensor, VisionCamera)
- Mock implementations for unit testing
- Teams implement FTC wrappers for their hardware
Documentation:
- LOCALIZATION_GUIDE.md - System architecture and usage
- GRID_SYSTEM.md - Field coordinate reference
- README.md - Quick start and examples
Usage:
weevil new my-robot --template localization
cd my-robot
./gradlew test # 3 tests pass in < 1 second
This teaches professional robotics concepts (sensor fusion, fault
tolerance, coordinate systems) not found in other FTC tools. Positions
Nexus Workshops as teaching advanced autonomous programming.
Updated src/templates/mod.rs to register localization template with
proper metadata and feature descriptions.
All tests passing (10/10 template tests).
Implements template-based project creation allowing teams to start with
professional example code instead of empty projects.
Features:
- Two templates: 'basic' (minimal) and 'testing' (45-test showcase)
- Template variable substitution ({{PROJECT_NAME}}, etc.)
- Template validation with helpful error messages
- `weevil new --list-templates` command
- Templates embedded in binary at compile time
Testing template includes:
- 3 complete subsystems (MotorCycler, WallApproach, TurnController)
- Hardware abstraction layer with mock implementations
- 45 comprehensive tests (unit, integration, system)
- Professional documentation (DESIGN_AND_TEST_PLAN.md, etc.)
Usage:
weevil new my-robot # basic template
weevil new my-robot --template testing # testing showcase
weevil new --list-templates # show available templates
This enables FTC teams to learn from working code and best practices
rather than starting from scratch.
All 62 tests passing.
Implements template-based project creation allowing teams to start with
professional example code instead of empty projects.
Features:
- Two templates: 'basic' (minimal) and 'testing' (45-test showcase)
- Template variable substitution ({{PROJECT_NAME}}, etc.)
- Template validation with helpful error messages
- `weevil new --list-templates` command
- Template files embedded in binary at compile time
Technical details:
- Templates stored in templates/basic/ and templates/testing/
- Files ending in .template have variables replaced
- Uses include_dir! macro to embed templates in binary
- Returns file count for user feedback
Testing template includes:
- 3 complete subsystems (MotorCycler, WallApproach, TurnController)
- Hardware abstraction layer with mock implementations
- 45 comprehensive tests (unit, integration, system)
- Professional documentation (DESIGN_AND_TEST_PLAN.md, etc.)
Usage:
weevil new my-robot # basic template
weevil new my-robot --template testing # testing showcase
weevil new --list-templates # show available templates
This enables FTC teams to learn from working code and best practices
rather than starting from scratch.
Cross-platform tool for generating clean, testable FTC robot projects
without editing the SDK installation.
Features:
- Standalone project generation with proper separation from SDK
- Per-project SDK configuration via .weevil.toml
- Local unit testing support (no robot required)
- Cross-platform build/deploy scripts (Linux/macOS/Windows)
- Project upgrade system preserving user code
- Configuration management commands
- Comprehensive test suite (11 passing tests)
- Zero-warning builds
Architecture:
- Pure Rust implementation with embedded Gradle wrapper
- Projects use deployToSDK task to copy code to FTC SDK TeamCode
- Git-ready projects with automatic initialization
- USB and WiFi deployment with auto-detection
Commands:
- weevil new <name> - Create new project
- weevil upgrade <path> - Update project infrastructure
- weevil config <path> - View/modify project configuration
- weevil sdk status/install/update - Manage SDKs
Addresses the core problem: FTC's SDK structure forces students to
edit framework internals instead of separating concerns like industry
standard practices. Weevil enables proper software engineering workflows
for robotics education.
