ROS 2 Robot Programming with Python
The step from a control panel to robot software: nodes, topics, services and messages; installing ROS 2 on Ubuntu, WSL2 or a Raspberry Pi; workspaces, Python packages and launch files; the encoders, lidar, motors and drive geometry underneath; a wall-following control loop you write yourself; SLAM, costmaps and autonomous navigation; arm kinematics and motion planning; and where C++, a ROS 1 bridge and a language model actually belong.

What you will learn
Install ROS 2 on Ubuntu or a Raspberry Pi and prove the graph is running; create a workspace and a Python package that builds with colcon; write publisher, subscriber and service nodes and define your own message; bring a whole system up with one launch file and inspect it with ros2 topic, rqt_graph and RViz; read a LaserScan and drive a base with Twist to follow a wall; explain how SLAM, costmaps and the global and local planners produce autonomous navigation; describe forward and inverse kinematics and why an arm still needs a motion planner; and read a C++ node, plan a ROS 1 to ROS 2 migration, and place a language model above the navigation stack rather than inside the control loop.

Requirements
- Who it is for
- Intermediate. Assumes basic Python and comfort with a Linux terminal. No robotics background needed, and no prior ROS.
- Software

A shareable EDWartens certificate
Finish every module and pass the final assessment, and the optional EDWartens certificate is yours. It carries a unique verification code on a public page anyone can check, so it stands up when a recruiter looks it up. See it below.
- Add it to your LinkedIn profile in one click
- Link it from a CV or portfolio, the URL is permanent
- Publicly verifiable by code, not a PDF anyone can edit
- Issued by EDWartens India, the training centre itself
The course itself stays free whether or not you ever buy one.
Stuck? Ask a practising engineer
A free course usually means a comment section and hope. This one does not. Every module has an Ask-your-trainer panel that reaches the same engineers who teach our paid programme: people who commission panels for a living, not moderators.
- Questions answered in the context of the module you are on
- The same engineers who teach the AEP programme
- Career tools, CV help and public job listings included
- Your progress and notes stay in your account for good

Common questions
Is the course really free?
Yes. Every module, every practice task and every assessment costs nothing, and there is no card on file. You create an account so your progress is saved and the assessments can be marked. The certificate is the only paid item, and only if you want it.
What certificate do I get?
An EDWartens Certificate of Completion, issued when you have finished every module and passed the final at 70%, with a verification code anyone can check. It is not a vendor credential and is never described as one.
Who made the video lessons?
The Construct Robotics Institute and ROBOTIS OpenSourceTeam, on their own YouTube channels, and they are credited at the foot of this page. EDWartens did not make the videos and neither creator is affiliated with EDWartens. What EDWartens wrote is the study plan, the notes, the practice tasks and the assessments.
What computer do I need?
A laptop that can run Ubuntu 22.04 or 24.04, with roughly 8 GB of RAM and 30 GB of free disk. Windows is fine through WSL2 or Docker. This is the one course in the free catalogue you cannot do on a phone alone: the notes and quizzes read on a phone, but ROS 2 and the simulator need a real machine.
Do I need to know Python first?
Basic Python is assumed: functions, classes, lists and dictionaries. You also need to be comfortable in a Linux terminal, since almost everything is run from one. No C++ is required; the last module only asks you to read a C++ node, not write one.
Some lessons were recorded on ROS 1. Does that matter?
The concept chapters from ROBOTIS were recorded for ROS 1, and each module says so. Nodes, topics, services, sensors, drive geometry, SLAM and kinematics are unchanged. Where the commands differ, the module notes give the ROS 2 form, and every hands-on lesson you follow at the keyboard is ROS 2.
Is this the same as an official ROS certification?
No. There is no single accrediting body for ROS, and this course is not endorsed by Open Robotics, ROBOTIS, The Construct or any vendor. It is preparation and practice. What you get from EDWartens is a Certificate of Completion for the work you did here.
Will this get me a robotics job in India?
It gets you past the first filter. ROS or ROS 2 is a named requirement in warehouse robotics, AMR and factory-robotics roles across Bangalore, Pune and Chennai, and most applicants from a maintenance or PLC background have never installed it. A course alone is not a hire. A simulated robot running on your own laptop that you can explain in an interview is what makes the difference.
