thanks for forwarding. ROS (Robot Operating System) is a kind of meta
operating system. It does not really handle OS functions, also it is
not real time. It's a great concept that boosts development in the
robotic area. It is based on a publisher / subscriber paradigm; you
implement your software as node which will publish and receive
messages. For example, if you wrap a face detection algorithm or
something in a ROS-node, it would subscribe to image messages and
probably publish a custom message with coordinates of a face, or maybe
another image with the face marked. This node can now receive images
from any node that publishes images. For example, a webcam-node. Or a
node that loads test-data from hard drive or maybe from a 3D-Simulator.
Also, there are a lot of components that already come with ROS. So if
we wanted to display the image with the face marked in it, we would
just need to make an image_view node (comes with ROS) to subscribe our
images. More complex components can display 3D point-clouds (for
example from a laser range finder), etc. ROS nodes register with a
master and they don't need to be on the same machine, as they can
communicate over network.<br>
<br>
Right now I'm trying to get a gpsd_client node to run on the OpenMoko.
On a remote PC a gpsd_viewer node will run, subscribing gpsFix messages
which it will use to display the Moko's location in a map from the
OpenStreetMap project. I'm planning to connect the Moko to a micro-
controler which then controls a RC-car. I tested this before, so I'm
optimistic that I will get it working. When it works I might add a
X-Box kinnect, which is already supported by ROS to capture 2D and 3D
visual information to enable the RC-car for autonomous driving. <br>

Subject: [ros-users] ROS running on Neo Freerunner<br>
Hi everyone,<br>
<br>
I spent some time on the weekend to get ROS diamondback running on the
OpenMoko smart phone Neo Freerunner. With it's WiFi, GPS,
Accelerometers and Linux capabilities it might be an alternative for
robot projects where a netbook is to large or to heavy.<br>
<br>
I put an installation guide here: <a moz-do-not-send="true" href="http://www.ros.org/wiki/freerunner" target="_blank" style="color: rgb(0, 0, 204);">http://www.ros.org/wiki/freerunner</a><br>
<br>
I was not really sure where to put it, as it is not really a tutorial
and also no stack description. So if the place is inappropriate, it
would be nice if someone could move it.<br>
<br>
