---------- Want to learn ROS really FAST and master the latest Robotics topics? ----------
:: Visit Robot Ignite Academy, the online Academy that teaches you ROS really FAST, from beginner to master, using only a web browser: https://goo.gl/LBT7EN
Robot Ignite Academy is an integrated ROS learning platform which contains a series of online ROS tutorials tied to online simulations, giving you the tools and knowledge to understand and create any ROS based robotics development.

---------- Are you a ROS expert and want to develop FAST your next ROS project? ----------

:: Then, use the ROS Development Studio (RDS) for your next project: https://goo.gl/EtFqmE
With the ROS Development Studio, you will be able to:
- Develop ROS programs for robots in a faster way, with an already setup IDE environment that includes autocomplete.
- Test the programs in real time on the provided simulated robots. Use the provided simulations or upload your own. Quickly see the results of your programming.
- Debug using graphical ROS tools.
- Test what you have developed on RDS in the real robot (if you have it :wink:
all of these are using ONLY a web browser without any installation and not limited by any operating system. DEVELOP FOR ROS USING WINDOWS, LINUX OR OSX.
