  • Control Rate: 20 Hz
  • Path Duration: 25.35 seconds

How to Reproduce

Prerequisites

  • Docker Desktop with WSL2 backend
  • X Server (VcXsrv) for GUI display

Quick Test

# 1. Start Docker container
cd docker
docker compose build dev
docker compose run --rm dev

# 2. Build workspace
source /opt/ros/humble/setup.bash
cd /ros2_ws
colcon build --symlink-install
source install/setup.bash

# 3. Run unit tests
colcon test --packages-select smooth_nav_core
colcon test-result --verbose

# 4. Launch demo (requires X Server)
ros2 launch smooth_nav_bringup demo.launch.py

Notes for Reviewers

  1. Docker Image: Pre-built as docker-dev:latest (6.13GB)
  2. GUI Demo: Requires X Server (VcXsrv) with "Disable access control"
  3. Headless Testing: All unit tests run without GUI
  4. Visualization: matplotlib-generated plots in docs/figures/
  5. Video: Short animation shows trajectory tracking (docs/figures/demo_animation.mp4)

This project is ready for submission.
