Hi all
I have a question
I'm trying write something about ROS, but a have at least two questions to answer.
I know that we can code ROS Packages using Python or C++, but, why these two languages were the selected languages?
For example: C++ probably is used because is fast, Python probably because is easy, less code etc.
But there is another reason to answer these questions?
The main questions are:
Why use Python and C to code ROS Packages?
How it works the ROS interface with Python and C++?
I'm sorry my not so good English,
Thank you in advance

> The aim of this contribution is to connect two previously separated
> worlds: robotic application
> development with the Robot Operating System (ROS) and statistical
> programming with R. This
> fruitful combination becomes apparent especially in the analysis and
> visualization of sensory data. We
> therefore introduce a new language extension for ROS that allows to
> implement nodes in pure R. All
> relevant aspects are described in a step-by-step development of a common
> sensor data transformation
> node. This includes the reception of raw sensory data via the ROS
> network, message interpretation,
> bag-file analysis, transformation and visualization, as well as the
> transmission of newly generated
> messages back into the ROS network.
