About TurtleBot 3
BB-8 is a droid character in the Star Wars franchise. Spherical with a free-moving domed head, BB-8 is portrayed by both a rod puppet and a remote-controlled robotic unit.
And the BB-8 robot simulation is the robot that you can program, control, navigate, and add sensors to in real life.
The BB-8 robot simulation is modeled as a spherical body with an hemispherical head attached to it. The base is a big tub sitting on the floor, with two wheels. You can use it to apply any ROS knowledge you have learned.

Tutorial - How to create a custom ROS service message. BB-8 Gazebo Simulator
This video shows step by step how to build your own custom ROS service message, and how to use it in your own service.
For this example, we will create a service that measures the amount of distance that the BB8 robot has moved. The service that we will provide is able to measure the amount of distance moved and provide that data either in meters or in miles, depending on how the request is done.
Tutorial - Measure distance traveled with Odometry with BB-8
In this video, you will learn how to measure the distance traveled by the BB-8 robot using the odometry topic. You will move it by sending cmd_vel Twist commands.
LIVE Class - How to Control a BB-8 with ROS2 Dashing
In this class, you will learn how to control a robot with ROS2 in order to follow a person.
** Why is so important to learn this topic? **
We also know that the migration to ROS2 is already happening, and it’s so important to get on it. Controlling a robot is the most important part of robotics, and using a ROS2 could be an interesting way to do it. If you know a little of ROS1 Basics, you’ll find many similarities, and working with topics, publishers, and subscribers is the main part of this.
