What is ROS?
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

A History of ROS (Robot Operating System)
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

Learning Python for Robotics
Python is a good choice if you want to become a robotics developer (i.e. program robots), especially 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++,

[ROS Mini Challenge] #5 – make a robot detect and avoid an obstacle
In this post, we will see how to make a robot detect and avoid an obstacle in its front. We will move the robot forward until it detects there’s an obstacle (the wall) closer than 1 meter. Then, we will stop the robot so that it does not collide with the wall. PS: This ROS

Developing Web Interfaces For ROS Robots #2 – Adding styles to the ROS control web page
Hello ROS Developers, This is the 2nd of 4 posts of the series Developing web interfaces for ROS Robots. In this post, we are going to add some styles to the web page using a very popular framework: Bootstrap. Furthermore, we will add a JavaScript framework to make our code look better: Vue.js. 1 – Loading the
