🪲 Weevil - FTC Project Generator

Bores into complexity, emerges with clean code.

A modern, cross-platform project generator for FIRST Tech Challenge (FTC) robotics that creates clean, testable, and maintainable robot projects — without forcing students to edit their SDK installation.

The Problem

The official FTC SDK requires teams to:

1. Clone the entire SDK repository
2. Edit files directly inside the SDK
3. Mix team code with framework code
4. Navigate through hundreds of unfamiliar files
5. Risk breaking the SDK with every change

This approach works against standard software engineering practices and creates unnecessary barriers for students learning to code. Industry uses libraries, JARs, and dependency management for good reasons — it's time FTC robotics caught up.

The Solution

Weevil generates standalone robot projects that:

• ✅ Keep your code separate from the SDK
• ✅ Support local unit testing (no robot needed!)
• ✅ Work with multiple SDK versions simultaneously
• ✅ Generate all build/deploy scripts automatically
• ✅ Enable proper version control workflows
• ✅ Are actually testable and maintainable
• ✅ Work seamlessly with Android Studio
• ✅ Support proxy/air-gapped environments

Students focus on building robots, not navigating SDK internals.

Installation

From Source

git clone https://www.nxgit.dev/nexus-workshops/weevil.git
cd weevil
cargo build --release
sudo cp target/release/weevil /usr/local/bin/

# Or add to PATH
export PATH="$PATH:$(pwd)/target/release"

Prerequisites

• Rust 1.70+ (for building Weevil)
• Java 11+ (for running Gradle)
• Android SDK with platform-tools (for deployment)
• FTC SDK (Weevil can install it for you)

---

Quick Start

1. Set Up Your Environment

# Check what's installed
weevil doctor

# Install everything automatically
weevil setup

# Or install to custom location
weevil setup --ftc-sdk ~/my-sdks/ftc --android-sdk ~/my-sdks/android

Weevil will:

• Download and install FTC SDK
• Download and install Android SDK (if needed)
• Set up Gradle wrapper
• Verify all dependencies

2. Create Your First Project

weevil new my-robot
cd my-robot

Weevil generates:

• Clean project structure
• Android Studio run configurations
• Example test files
• Build and deploy scripts
• Git repository with .gitignore

3. Write Some Code

Create src/main/java/robot/MyOpMode.java:

package robot;

import com.qualcomm.robotcore.eventloop.opmode.TeleOp;
import com.qualcomm.robotcore.eventloop.opmode.LinearOpMode;

@TeleOp(name="My OpMode")
public class MyOpMode extends LinearOpMode {
    @Override
    public void runOpMode() {
        telemetry.addData("Status", "Initialized");
        telemetry.update();
        
        waitForStart();
        
        while (opModeIsActive()) {
            telemetry.addData("Status", "Running");
            telemetry.update();
        }
    }
}

4. Test Locally (No Robot!)

./gradlew test

Write unit tests in src/test/java/robot/ that run on your PC. No need to deploy to a robot for every code change!

5. Deploy to Robot

# Build APK
./build.sh

# Deploy via USB
./deploy.sh --usb

# Deploy via WiFi
./deploy.sh --wifi -i 192.168.49.1

# Auto-detect (tries USB, falls back to WiFi)
./deploy.sh

---

Android Studio Setup

Opening a Weevil Project

1. Launch Android Studio
2. Choose Open (not "New Project")
3. Navigate to your project directory (e.g., my-robot)
4. Click OK

Android Studio will index the project. After a few seconds, you'll see:

• Clean file tree - Only src/, scripts, and essential files visible
• Run configurations - Dropdown next to the green play button shows:
  • Build - Builds APK without deploying
  • Deploy (auto) - Auto-detects USB or WiFi
  • Deploy (USB) - Forces USB connection
  • Deploy (WiFi) - Forces WiFi connection
  • Test - Runs unit tests

First-Time Setup: Shell Script Plugin

Important: Android Studio requires the Shell Script plugin to run Weevil's deployment scripts.

1. Go to File → Settings (or Ctrl+Alt+S)
2. Navigate to Plugins
3. Click the Marketplace tab
4. Search for "Shell Script"
5. Install the plugin (by JetBrains)
6. Restart Android Studio

After restart, the run configurations will work.

Running from Android Studio

1. Select a configuration from the dropdown (e.g., "Deploy (auto)")
2. Click the green play button (▶) or press Shift+F10
3. Watch the output in the Run panel at the bottom

That's it! Students can now build and deploy without leaving the IDE.

Platform Notes

• Linux/macOS: Uses the Unix run configurations (.sh scripts)
• Windows: Uses the Windows run configurations (.bat scripts)
• Android Studio automatically hides the configurations for the other platform

Advanced Usage

Proxy Configuration

Corporate Environments

# Set proxy for all Weevil operations
weevil --proxy http://proxy.company.com:8080 setup
weevil --proxy http://proxy.company.com:8080 new robot-project

# Or use environment variables (auto-detected)
export HTTPS_PROXY=http://proxy:8080
export HTTP_PROXY=http://proxy:8080
weevil setup  # Automatically uses proxy

Air-Gapped / Offline Installation

If you're on an isolated network without internet:

1. Download SDKs manually on a connected machine:

   • FTC SDK: git clone https://github.com/FIRST-Tech-Challenge/FtcRobotController.git
   • Android SDK: Download from https://developer.android.com/studio
   • Gradle: Download distribution from https://gradle.org/releases/

2. Transfer to isolated machine via USB drive

3. Install using local paths:

   weevil setup --ftc-sdk /path/to/FtcRobotController --android-sdk /path/to/android-sdk
   

Bypass Proxy

# Force direct connection (ignore proxy environment variables)
weevil --no-proxy setup

Multiple SDK Versions

Working with multiple SDK versions? No problem:

# Create project with specific SDK
weevil new experimental-bot --ftc-sdk /path/to/sdk-v11.0

# Later, switch SDKs
weevil config experimental-bot --set-sdk /path/to/sdk-v11.1

# Rebuild with new SDK
weevil upgrade experimental-bot
cd experimental-bot
./build.sh

Upgrading Projects

When Weevil releases new features:

weevil upgrade my-robot

This updates:

• Build scripts
• Deployment scripts
• Gradle configuration
• Android Studio run configurations
• Project templates

Your code in src/ is never touched.

System Maintenance

# Check what's installed
weevil doctor

# See what can be uninstalled
weevil uninstall --dry-run

# Remove specific components
weevil uninstall --only 1  # Removes FTC SDK only

# Full uninstall (removes everything Weevil installed)
weevil uninstall

Cross-Platform Development

All scripts work on Windows, Linux, and macOS:

Linux/Mac:

./build.sh
./deploy.sh --wifi

Windows:

build.bat
deploy.bat

Android Studio: Works identically on all platforms

---

Project Configuration

Each project has a .weevil.toml file:

project_name = "my-robot"
weevil_version = "1.1.0"
ftc_sdk_path = "/home/user/.weevil/ftc-sdk"
ftc_sdk_version = "v10.1.1"
android_sdk_path = "/home/user/.weevil/android-sdk"

You can edit this manually or use:

weevil config my-robot                    # View config
weevil config my-robot --set-sdk /new/sdk # Change SDK

---

Development Workflow

Recommended Git Workflow

# Create project
weevil new competition-bot
cd competition-bot

# Project is already a git repo!
git remote add origin https://nxgit.dev/team/robot.git
git push -u origin main

# Make changes
# ... edit code ...
./gradlew test
git commit -am "Add autonomous mode"
git push

# Deploy to robot
./deploy.sh

Testing Strategy

1. Unit Tests - Test business logic on your PC

   ./gradlew test
   # Or from Android Studio: select "Test" and click Run
   

2. Integration Tests - Test on actual hardware

   ./build.sh
   ./deploy.sh --usb
   # Run via Driver Station
   

Team Collaboration

Project Structure is Portable:

# Team member clones repo
git clone https://nxgit.dev/team/robot.git
cd robot

# Check SDK location
weevil config .

# Set SDK to local path (if different from .weevil.toml)
weevil config . --set-sdk ~/ftc-sdk

# Build and deploy
./build.sh
./deploy.sh

Android Studio users: Just open the project. The .idea/ folder contains all run configurations.

Architecture

How It Works

1. Project Generation

   • Creates standalone Java project structure
   • Generates Gradle build files that reference FTC SDK
   • Sets up deployment scripts
   • Creates Android Studio run configurations

2. Build Process

   • Runs deployToSDK Gradle task
   • Copies your code to FTC SDK's TeamCode directory
   • Builds APK using SDK's Android configuration
   • Leaves your project directory clean

3. Deployment

   • Finds built APK in SDK
   • Connects to Control Hub (USB or WiFi)
   • Installs APK using adb

4. Proxy Support

   • reqwest HTTP client respects --proxy flag and HTTPS_PROXY env vars
   • git2/libgit2 gets temporary proxy env vars during clone/fetch
   • Gradle wrapper reads HTTPS_PROXY natively

Why This Approach?

Separation of Concerns:

• Your code: my-robot/src/
• Build infrastructure: my-robot/*.gradle.kts
• FTC SDK: System-level installation
• IDE integration: Auto-generated, auto-upgraded

Benefits:

• Test code without SDK complications
• Multiple projects per SDK installation
• SDK updates don't break your projects
• Proper version control (no massive SDK in repo)
• Industry-standard project structure
• Students use familiar tools (Android Studio)

---

Testing

Weevil includes comprehensive tests:

# Run all tests
cargo test

# Run specific test suites
cargo test --test integration
cargo test --test project_lifecycle
cargo test --test proxy_integration
cargo test config_tests

Test Coverage:

• ✅ Project creation and structure
• ✅ Configuration persistence
• ✅ SDK detection and validation
• ✅ Build script generation
• ✅ Upgrade workflow
• ✅ CLI commands
• ✅ Proxy configuration and network operations
• ✅ Environment setup and health checks

weevil setup

# Or specify custom location
weevil new my-robot --ftc-sdk /custom/path/to/sdk

"adb: command not found"

Install Android platform-tools:

Linux:

# Weevil can install it for you
weevil setup

# Or install manually
sudo apt install android-tools-adb

macOS:

brew install android-platform-tools

Windows: Download Android SDK Platform Tools from Google or run weevil setup.

"Build failed"

# Clean and rebuild
cd my-robot
./gradlew clean
./build.sh

# Check SDK path
weevil config .

# Verify system health
weevil doctor

"Deploy failed - No devices"

USB:

1. Connect robot via USB
2. Run adb devices to verify connection
3. Try ./deploy.sh --usb

WiFi:

1. Connect to robot's WiFi network
2. Find Control Hub IP (usually 192.168.43.1 or 192.168.49.1)
3. Try ./deploy.sh -i <ip>

Android Studio: "Unknown run configuration type ShellScript"

The Shell Script plugin is not installed. See Android Studio Setup for installation instructions.

Philosophy

Why "Weevil"?

Like the boll weevil that bores through complex cotton bolls to reach the valuable fibers inside, this tool bores through the complexity of the FTC SDK structure to help students reach what matters: building robots and learning to code.

Design Principles:

1. Students first - Minimize cognitive load for learners
2. Industry practices - Teach real software engineering
3. Testability - Enable TDD and proper testing workflows
4. Simplicity - One command should do one obvious thing
5. Transparency - Students should understand what's happening
6. Tool compatibility - Work with tools students already know
