Course Content Breakdown
Weeks 1-2: Foundations of ROS & the SUMMIT XL Robot (Lesson 1)
Learning Objectives: Understand ROS fundamentals (Nodes, Topics, Messages, Services, Actions). Set up a ROS workspace. Become familiar with the architecture and capabilities of the SUMMIT XL robot.
Key Vocabulary: ROS, Node, Topic, Message, Service, Action, roscore, Catkin Workspace, SUMMIT XL.
Content: ROS is the backbone of modern robotics, providing a flexible framework that allows complex software components to communicate seamlessly. Think of it as the central nervous system for a robot. In this first lesson, we’ll demystify its core components: nodes (individual programs), topics (data channels), messages (the data itself), and services/actions (for request-based tasks). We’ll guide you through setting up your ROS environment and configuring your first workspace using Catkin (ROS 1) or Colcon (ROS 2), which organize your code into reusable packages. We will then introduce your primary tool: the SUMMIT XL robot. You’ll get a deep dive into its physical characteristics, its comprehensive sensor suite (LiDAR, cameras, IMU), and its robust locomotion system. Understanding this hardware is crucial for programming it effectively. Finally, we’ll launch a SUMMIT XL simulation in Gazebo and use essential command-line tools to start interacting with it.
Practical Hands-on Examples: Install ROS Noetic or ROS 2 Humble. Create a new development workspace. Launch the SUMMIT XL simulation in Gazebo. Use `rostopic list` / `ros2 topic list` to see what data the robot is publishing. Use `rostopic echo` / `ros2 topic echo` to inspect live sensor data like laser scans and odometry.
Weeks 3-4: Basic ROS Programming & SUMMIT XL Robot Teleoperation (Lesson 2)
Learning Objectives: Write basic ROS nodes in Python to publish and subscribe to topics. Control the SUMMIT XL robot using keyboard teleoperation. Understand and create `roslaunch` files for managing multiple nodes.
Key Vocabulary: Publisher, Subscriber, Teleoperation, CmdVel, roslaunch, YAML.
Content: With a grasp of ROS communication, it’s time to write your own code. We’ll start with Python, a favorite in the robotics community for its clarity and power. You will learn to write a publisher node that sends velocity commands to the SUMMIT XL robot and a subscriber node that listens to its sensor data. The best way to solidify these concepts is by taking direct control. We will build a simple teleoperation node that translates your keyboard strokes into movement commands, allowing you to drive the simulated SUMMIT XL robot around its environment. As your projects grow, launching each node manually becomes inefficient. Enter `roslaunch` (or ROS 2 launch files). These powerful configuration files allow you to start up your entire robotic system—all the nodes, parameters, and configurations—with a single command. We will create a custom launch file for our teleoperation system, bringing professional-grade workflow to your project.
Practical Hands-on Examples: Develop a Python publisher to send `Twist` messages to the `/cmd_vel` topic. Write a Python subscriber that prints the robot’s odometry data from the `/odom` topic. Implement a keyboard teleoperation script to drive the SUMMIT XL robot in the simulator. Create a launch file that starts your publisher, subscriber, and any other necessary nodes together.
