Hi ROS Community,

Join our next ROS Developers Open Class to learn about **Perception with AprilTags**. Perception is a crucial aspect of modern robotics, and mastering tools like AprilTags can significantly enhance a robot’s ability to understand and interact with its environment. We will explore the fundamental concepts and practical applications of **AprilTags in ROS2**.

This free class welcomes everyone and includes a practical ROS project with code and simulation. Alberto Ezquerro, a skilled robotics developer and head of robotics education at The Construct, will guide this live session.

## What you’ll learn:

- Understand what **AprilTags** are and how they can be used in robotic perception.
- Learn how to detect **AprilTags in an image stream**.
- Practical examples using **simulated and real BotBox robots**.

## The robot we’ll use in this class:

Simulated & Real **BotBox**
