Re: ROS (Robot Operating System) on RPi

Now that is an easy problem to solve :) I reduced the file size to a minimum, so you would not have so much to download. You will need to increase the size of the partition by using gparted on a Linux workstation (that is how I did it) or use sudo raspi-config and select 'expand_rootfs' Also feel fr...

Re: ROS (Robot Operating System) on RPi

I checked the md5sum of the img and the tar.gz file:

Re: ROS (Robot Operating System) on RPi

I do not know which instructions you follow, we are build upon Rasbian. You can find the latest instruction procedure here: http://www.ros.org/wiki/groovy/Installa ... ian/Source
There is also an iso file that you can just dd onto your card.

Re: ROS (Robot Operating System) on RPi

I have never seen this error. Is it just a warning or does it not let you log in at all? Is the image working for anyone else?

Re: ROS (Robot Operating System) on RPi

Hey guys, I compiled the desktop package and got it to compile for almost every single package. The only packages that did not work were PCL and rviz. PCL needs a lot of SRAM to compile and threw some read/write errors on the swapfile. If anybody gets either package to compile, please share, I will ...

Re: ROS (Robot Operating System) on RPi

I got almost everything compiled, PCL does not really like me. I also had read/write errors on my SD card. Hope I did not break it :D
Compiling only PCL takes about 24 hours -.-

Re: ROS (Robot Operating System) on RPi

How is your Desktop build coming along? I found that it takes an eternity to compile. OpenCV2 took about 7 hours :( I think I resolved all system dependencies, so it "should" build all the way through now. 24 packages down, 127 to go. I hope my company will let me share the iso with you guys when I ...

Re: ROS (Robot Operating System) on RPi

That was not supposed to be an offence Bob, sorry if you took it that way. I just tried to save some time, which obviously did not work in the end XD I found the RasPi to work really slow because i was working on a Class 4 SD Card. I will switch to a class 10 and see how that goes. I hope I can star...

Re: ROS (Robot Operating System) on RPi

thanks, I did not plan to run any graphical stuff, so I skipped this apt-get instruction.
I edited the wiki, so lsb-release will be installed in the ROS BASE section

Re: ROS (Robot Operating System) on RPi

I am just trying to replicate your results, but rosdep does not work because it cannot find the OS. Did you use the fix from here?
http://wiki.gumstix.org/index.php?title=Turtlecore
Or did it work without a fix?

Re: ROS (Robot Operating System) on RPi

I did not build flann yet, because my turtlebot does not depend on it. Did you use this yaml file:

Re: ROS (Robot Operating System) on RPi

are you using catkin or rosbuild to compile the Desktop version? If you are using catkin, I might be able to help you, since I already compiled a lot of packages for the gumstix.
Which packages do not compile?

Re: ROS on RPi

I like the idea of synchronizing effort, but what do you want to upload to github? I am also interested in getting ROS running on the RasPi. Right now I am working on the gumstix, but this will only be a matter of days I hope. I will be working on bringing groovy to the RasPi, so if anyone else is i...
