Ron,
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.
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.
best regards,
Jan

sending this item along seen on the ROS list.
Not sure if OpenMoko folks have already seen it.
A future board similar to SIE nee SAKC would
benefit from a real time OS. This one [ROS]
appears to be open and free and widely supported.

Subject: [ros-users] ROS running on Neo Freerunner
Hi everyone,
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.
I put an installation guide here: http://www.ros.org/wiki/freerunner
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.
Jan
