Away notice
by Tim Niemueller
Hi robot enthusiasts.
I'm going to be away for a short vacation from Wednesday May 28th 2008
to Sunday June 1st 2008.
Jeff, if you could have a look at the review maybe we can get Player in
before that -- if there are no major issues found that is...
Arindam, did you have a look at the Player package and maybe even used
it with Stage/Gazebo?
Regards,
Tim

Player Review Request
by Tim Niemueller
Hi all.
I have posted a review request for Player
(https://bugzilla.redhat.com/show_bug.cgi?id=448025). Please have a look
and someone take it :-)
The scratch build isn't finished for ppc64, yet. I don't expect any
problems though and I'm tired and need to sleep...
Regards from Aachen,
Tim

Postpone meeting
by Tim Niemueller
Hi there.
I've to go to the vet with our dog tonight and thus I can't make it to
the meeting at 16:00 UTC. Is anyone oppose to delay the meeting either
by two hours today or to the same time tommorrow?
Jef, Arindam, Heyadat?

Player Progress
by Tim Niemueller
Hi there.
I made some progress with the Player package but it's not done, yet.
After fixing some (trivial) GCC 4.3 related problems I'm currently
fighting with rpath being used. I have to remove it but it seems to be
necessary to link the server. I'm tired, have to sleep about it.
Tomorrow and probably also on Sunday won't be much time to work on this
so I probably will have nothing before Monday or even Tuesday. Arindam,
I'd suggest you have a closer look at Stage/Gazebo already. Although
Player is a dependency you could start creating specs or so if you are
otherwise bored ;-)
I'll keep you posted,
Tim

Thanks for getting the list going, btw.

Probably not many people are. I've found that, in the embedded Linux
world in general, only about 1-2% of the developers I've met are
familiar with I2C.
That said, I2C is the simplest bus protocol there is. It was designed
that way for a reason. My advice here is to just go for it.

I agree. This is a good goal to shoot for.

I have the Tech Challenge Robotics Kit in hand
by Jef Spaleta
So I saw my teacher friend.
I have what I think is the entire $900 kit based on the Lego
mindstorms NXT which should be the kit uses in next year's
Tech Challenge.
Here's the blog concerning the new platform
http://www.firsttechchallenge.blogspot.com/
I'm going to try to leverage my Fedora Board creds, and see if I can
get a line of communication going with the people behind the new
platform.
I'm sure you've seen the Mindstorm NXT kit. The new tech challenge
platform consists of the mindstorms kit with an additional
motor/sensors/servo multiplexor box that communicates via i2C back to
the main NXT brick. Raise your hand if you are experienced with i2c
communication for robotics.
On top of that you get the metal structural hardware to put a somewhat
robust robot together so you don't have to use plastic lego components
as main structural elements. I'll take pictures of what I have in
hand. Its not pretty, its a de-commissioned robot they used in April
at the demo competition in Atlanta.
So big picture time..... Getting player/stage to be able to model a
specific mindstorm nxt configuration and then being able to use
player/stage to control the that mindstorm nxt configuration via
bluetooth would be...dreamy.

Welcome to the world of robotics in Fedora
by Tim Niemueller
Hi Jeff and Arindam.
As you see the mailing list has been created and we can start
discussing! Here are the first notes I'd like to share.
I could not resist and gave packaging Player a try. It's not done yet
but I hope to have something this weekend but there is another
appointment and thus I don't know for sure. Additionally there was an
F-9 installation and new stuff to play with slowing me down a bit :-)
Arindam, what's your progress on Player?
I've talked to the guy who used Player/Gazebo in our project: the
problem that he faced was, that when adding a new sensor model, it would
only be compiled if it was used in another model. Seems to be a buildsys
related issue that has to be re-evaluated.
We should have a look anyway about proper ways to extend the base
functionality of Gazebo and if this can be done without using the source
of Gazebo. All that should be necessary is a yet-to-be-defined -devel
package. It should also provide some well-known paths where to put
custom code, like /usr/lib{,64}/gazebo/... and ~/.gazebo/... This may
need some tweaking but I don't know. Jeff, this would be something you
intern could look into, right?
Regards from Aachen,
Tim
