Advanced SLAM in ROS2: Mapping with Cartographer

In this tutorial, you’ll learn how to use Google’s Cartographer with ROS2 to perform advanced 2D SLAM (Simultaneous Localization and Mapping). Cartographer is a real-time SLAM algorithm that provides loop closure and accurate map construction in dynamic environments. We’ll use a simulated TurtleBot3, but the steps are adaptable to real robots. 📝 Requirements – ROS2 […]
Creating a 2D map with GMapping (ROS)

In this tutorial, you will learn how to build a 2D map of an environment using the GMapping SLAM algorithm in ROS1. This process is fundamental for autonomous navigation as it allows the robot to understand and represent its surroundings. 📝 Requirements – ROS1 installed (e.g., Noetic) – `slam_gmapping` package – Simulated robot with LIDAR sensor (e.g., […]
Navigation with move_base and AMCL (ROS)

In this tutorial, you will learn how to autonomously navigate a mobile robot in ROS1 using the `move_base` package for path planning and `amcl` for probabilistic localization on a prebuilt map. We will use a simulated robot (e.g., TurtleBot3) with a map previously generated using SLAM. 📝 Required components ROS1 installed (e.g., Noetic on Ubuntu […]
How to use i2c lcd with Arduino

In this tutorial, you’ll learn how to use a 16×2 LCD display with an I2C interface using the Adafruit_LiquidCrystal library. The code example shows how to display a counter that increments every second and blinks the backlight to create a visual effect. What is an I2C LCD Display? When working with LCD screens and microcontrollers […]
