ROS development on Linux, Windows and macOS

Article Robotics

Historically ROS has been developed on top of Ubuntu, relying on the distribution as a stable base providing tools (like GCC, CMake, Python to name a few) and libraries (such as Boost, Eigen, PCL) and following its release cycle (a distribution per year, an LTS every two years). This synergy has worked great for more

Publishing sonar readings with micro-ROS on the Raspberry Pi Pico

Article Robotics

In this post, we will see how to wire up an HC-SR04 range sensor to the Raspberry Pi Pico and publish its readings to the ROS 2 graph using micro-ROS. This builds upon the previous post ‘Getting started with micro-ROS on the Raspberry Pi Pico’. As such, I’d encourage you to read it first if

Getting started with micro-ROS on the Raspberry Pi Pico

Article Robotics

In this post we will see how the Raspberry Pi Pico can natively speak to a ROS 2 graph using micro-ROS. We will set up a project in VSCode, compile and upload it to the microcontroller. We thus assume that you are somewhat familiar with ROS 2 development and VSCode. What is this all about?

Feeling at home in a LXD container

Article Robotics

In this post, we will see how we can containerize our home in LXD simply managing our personal configuration files – a.k.a. dotfiles. Yeah dotfiles, named after their common ~/.my_config form, you know, all of those small configuration files lying across our $HOME. In other words, how one can change the house while keeping the

How to set up TurtleBot3 in minutes with snaps (2/2)

Article Robotics

Welcome to part two of our TurtleBot3 set up, namely the turtlebot3c project. In part one, we rearranged the launch files and configuration files of the TurtleBot3 so that we have four entry points to our robot’s functionalities. One per application in our snap. Now it is time to build the snap so that it

Components vs. Plugins in ROS 2

Article Robotics

After our series of post about ROS 2 CLI tools (1, 2), we continue exploring the ROS 2 realm taking a look at ROS 2 components and more specifically, how they compare to plugins. spoiler alert: Long story short, components are plugins. Short story long? Is that a thing? Well plugins and components are indeed

Creating a ROS 2 CLI command and verb

Article Robotics

Following our previous post on ROS 2 CLI (Command Line Interface), we will see here how one can extend the set of existing CLI tools by introducing a new command and its related verb(s). As support for this tutorial, we will create a ‘Hello World’ example so that the new command will be hello and
