Creating a Python script under ROS2
In this tutorial, we'll look at how to create and run Python scripts under ROS2. This will enable you to create your own nodes and start developing under ROS. Create a workspace A good practice when developing under ROS2 is to create workspaces in which to install the...
Installing ROS2 on Raspberry Pi
In this tutorial, we'll look at how to install ROS2 on a Linux machine, in particular a Raspberry Pi 4 running Ubuntu. ROS2 is an interesting framework to tackle when working on embedded systems such as robots. Hardware Computer with Internet access 32GB SD card...
Sending long character strings via BLE
Bluetooth Low Energy (BLE) has a known limit of 20Bytes on the length of strings sent. There are ways of overriding this limit. Hardware In this tutorial, we'll send data from an Android application, developed under React Native, to an ESP32. The methods described may...

Develop a serial monitor with Python
When developing a project with Arduino, Raspberry Pi or any microcontroller you will certainly have to create a graphical interface like, a serial monitor, for the management of the system (debugging, observing measurements, launching actions, etc.). There are a lot...
Make your robot interactive with an LCD16x2 screen
When making a robot, it can be fun to give it more life by making it interactive. For example, it is possible to give him the floor, make him make sounds or change color depending on external actions and his states. In this project, we will use an LCD16x2 screen,...
A robot that detects and avoids obstacles
Once your robot is mounted and the electronics are working properly, it's time to give it its functionality. The features are "Who am I?" "And" Why am I on this Earth? Of a robot. So many existential questions that only you can answer. In the case of a mobile robot,...
