ROS2 tutorial: Nodes and topics // Getting started with Robot Operating System using Turtlesim

In this tutorial, learn about ROS2 nodes and topics using the turtlesim package.

This tutorial is aimed towards beginners and doesn't require any prior knowledge of ROS. In this tutorial you will learn about 2 core concepts of ROS2 - nodes and topics. To make it easy to understand, we will be using Turtlesim - a simple simulator.

========== ABOUT ME ==========
I am a Robotics Engineer. My goal is to develop algorithms for realizing robot operations in the real world. And it is just absolute fun to code and solve problems. Read more about my projects work at https://kgada.info/

I started my journey in Robotics by working on small personal projects such as a line follower with an arduino. I then pursued and graduated with a Masters in Robotics from University of Maryland in 2017.

After graduation, I have worked at Reality AI, Qualcomm and Brain Corp. With 3 years of professional experience, I understand that one of the biggest challenge in Robotics is implementation of algorithms in the real world and that is where my expertise are. Digging in at ground zero to implement solutions.

I spoke about my experience as a roboticist at Brain Corp on the RoboHub podcast, check it out here: https://robohub.org/commercializing-robot-brains/

I am also a YouTuber, it is my way of giving back and helping the community grow. As a women and an international student in the US, I am aware of the challenges to break through and have a successful career. I share my insights and also teach robotics through my youtube channel.
