You'll code nodes that publish twist messages for velocity control, compute odometry from encoder ticks, and visualise the robot's pose in rviz2 — the essential stack for any modern robotics engineer. This kit is built for students and enthusiasts who want to stop simulating and start navigating in the physical world.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eA ROS2‑enabled differential drive robot that responds to teleoperation twist commands, tracks its position accurately through encoder‑based odometry, and executes a basic waypoint navigation routine. The MPU6050 IMU supplements the odometry for orientation, and the entire robot state can be viewed in real time on rviz2.
