Away notice
by Tim Niemueller 26 May '08

26 May '08

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?

Player Review Request
by Tim Niemueller 23 May '08

23 May '08

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...

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 20 May '08

20 May '08

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 -- Tim Niemueller <tim(a)niemueller.de> www.niemueller.de ================================================================= Imagination is more important than knowledge.

Thanks for getting the list going, btw. On Thursday, 15 May 2008 at 16:10:17, Jeff Spaleta wrote: > ... > I'm sure you've seen the Mindstorm NXT kit.

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. > So big picture time.....

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

I have the Tech Challenge Robotics Kit in hand
by Jef Spaleta 15 May '08

15 May '08

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. -jef

Welcome to the world of robotics in Fedora

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?
