2015-01-26 19:15:13 -0500 commented answer Transfert specific topics from an ROS master to another

Thanks for the help but i figured out how to deal with it using the foreign relay package, even though it is not the best solution. Keep it up :)

Thank you for the answer, can you give me a quick explain of how to use the topic_proxy? that would be very helpful to me.

2015-01-19 20:28:43 -0500 asked a question Transfert specific topics from an ROS master to another

Hi all! i was working with two computers using the same ROS master as described at this it is working well but the problem is that i want to transfer only some specific topics and not all topics. since the two packages i am using in each computer publish on tf, i have problem while recording the bag file. can someone suggest a better way to do it? what i mean is that i run ROSCORE in each of two machines(computers) and i send the topics that i wanted from a master to another.

PS: i was about to use the foreign_relay package but it seems it is not possible to download it(if someone could give me the link to download it, that would be perfect :D)

Thanks! all help will be welcome.

HI everyone i am trying to record my bag with ccny_rgbd packages. for launching the ccny camera driver i used the command:

roslaunch ccny_openni_launch openni.launch

and for recording the bag:

rosbag record -a

but i get some error saying:

At the end the bag is recorded but not properly, some seconds are just skipped due to this error. can someone help me to solve this issue? thanks
