Hello world easy start

Hello anybody!

I would like to ask some easy questions:)

I had just started to learn Orocos capabilities.

Could you tell me: is it some difference when using Orocos and couple Orocos + ROS?

For my aims (now i have realised it) that it is better to use Orocos. I installed ROS firstly, after what i had installed Orocos(ROS integrated variant). Now it is impossible to setup Orocos to another path.

And second request (maybe more complicated, but...): i'm not a professional programmer so it is difficult to understand all nuances. If anybody could send to me an example with some kind of readme (good comments at code is also expected) and with detailed way of what i must to do, for example,for programm wich will do smth with kdl lib for example. I would be very happy. For a person wich have a little experience at cpp it is very hard to walk through your tutorials.

With best regards, Anton!

The Orocos-ROS integration is a pure addon onto the Orocos toolchain, it
allows a seamless integration of the ROS middleware.

You can install the toolchain without the ros communication from the ROS
packages: orocos-electric-orocos-toolchain. This package only contains the
pure Orocos software.

If you really want to control the path of the Orocos source you can easily
uninstall the ros-package and follow the following guidelines:

After the installation it is adviced to go through the RTT-exercises, which
provides a walk-through for all the RTT concepts:
