How do robots navigate autonomously in unknown environments?
In this project, I built a complete ROS 2 Navigation (Nav2) system where a mobile robot can localize itself, plan a path, and reach a goal automatically using LiDAR and real-time sensor data.
This simulation demonstrates how modern robots perform autonomous navigation using the powerful Nav2 stack in ROS 2.
🔥 What This Project Shows
➡ Differential drive robot simulation in Gazebo
➡ Autonomous navigation using ROS 2 Nav2 stack
➡ LiDAR-based obstacle detection and avoidance
➡ Path planning and execution in real time
➡ Localization using AMCL
➡ RViz visualization (costmaps, paths, robot pose)
➡ Manual control using keyboard (teleop)
⚙️ Technologies Used
ROS 2 Humble
Nav2 (Navigation Stack)
Gazebo (Ignition / GZ Sim)
RViz
LiDAR Sensor
TF2, Odometry
🧠 How It Works
1️⃣ Launch the simulation
2️⃣ Set initial robot pose in RViz
3️⃣ Select goal position
4️⃣ Nav2 computes optimal path
5️⃣ Robot navigates autonomously while avoiding obstacles
🎯 Key Learning Outcomes
✔ Understanding ROS 2 Navigation pipeline
✔ Path planning & obstacle avoidance
✔ Localization using AMCL
✔ TF tree and coordinate frames
✔ Simulation-based robotics development
💡 Real-World Applications
