Today, we embark on our very own Pokémon adventure using ROS 2 for navigation. Your goal is for your Create 3 Robot to perform the expected behaviors to complete all field research tasks. Here are the rules:

• Maximum of 3 people per team
• 1 Pokémon per team: 1 Create 3 Robot and 1 Raspberry Pi
• ROS 2 command line commands (e.g., ros2 topic pub … ) are strictly prohibited - all code must be written in a Python script using rclpy

Your Backpack - Key Resources

The very best way to learn ROS 2 is to start working with it. But, we wouldn’t send you out on a journey without supplies in your backpack. Here are some links to key pieces of information that you will need as you brave the wilderness.

• Sample ROS 2 Code Specific to this Challenge
• Create 3 Documentation - Please do not modify any settings on the Create 3 Robot!
• Create 3 Interfaces Documentation
• ROS 2 Pre-Made Interfaces Documentation

Communicating with Your Pokémon

Each Pokémon is fully equipped with a Create 3 Robot and a Raspberry Pi 4. Your Pi has been pre-imaged with Ubuntu 22.04 (a Linux based distribution) and both the Pi and Create have ROS 2 Humble pre-installed. You will communicate directly with your Pi via Wi-Fi, which will send commands to your Create via a hardwired ethernet over USB connection.

Two options to connect to your Raspberry Pi:

• Secure Shell (SSH)
• Virtual Network Computing (VNC)

Once you’re connected, create a folder titled ros2challenge in your user folder and save all code within this folder.
