INTRODUCTION TO ROBOT OPERATING SYSTEM (ROS) If you are reading this, it is because you either are or you want to become a ROS developer. Basically a ROS developer is somebody who wants to build programs for robots based on ROS. Yeah, but what is ROS? How can I learn ROS? How can I start developing

ROS (Robot Operating System) is now very popular among roboticists. Researchers, hobbyists, and even robotics companies are using it, promoting it and supporting it. However, it was not always like that. Do you know ROS history? In the early days, ROS was an unknown only used by a bunch of robotics freaks. How did ROS reach

Python is a good choice if you want to become a robotics developer (i.e. program robots), specially if you want to program your robots with ROS. On a previous post, I discussed about whether to learn ROS using C++ or using Python. On that post, I argued that, if you know neither Python nor C++

Hey ROS Developers! In this post, we are going step-by-step to install ROS Melodic in a fresh Ubuntu 18.04. I’m using a regular desktop computer, the one I use to support me on ROS development. Let’s do it! Step 1 – Configuration The first step is adding the ROS repository to your ubuntu sources.list

Today, I would like to dedicate the episode to those ROS developers that use ROS with outdoor robots. You know that most of the ROS robots are basically indoor ones, where the level of control of the environment is a little bit higher. When you move outdoors…. Then things start to complicate a little bit

In this short post, we will demonstrate how to avoid a very common mistake most ROS beginners make: missing execute permission on the Python file. Step 1: Create a Project (ROSject) on ROSDS Head to http://rosds.online and create a project with a similar configuration as the one shown below. You can change the details as you like, but

In this episode of ROS2 Tutorials Series, you will learn how to create a simple ROS2 custom message for Topics. We are going to use a ROS2 (Dashing) installation for this, but you don’t need to install ROS, as we will use the ROS Development Studio (ROSDS), an online platform that provides access to ROS2 and

In this post, you will learn how to communicate between ROS1 & ROS2 with ros1_bridge. You will see how to set up the ros1_bridge package in order to send ROS2 commands to control a TurtleBot2 simulation running in ROS1 Melodic.
