Hi all, I am trying to run irobot_create_2_1 driver , i do rosmake successfully however i cannot run it. this is the error i am getting
rosrun irobot_create_2_1 driver.py Traceback (most recent call last): File "/opt/ros/electric/stacks/brown_drivers/irobot_create_2_1/bin/driver.py", line 15, in <module> from irobot_create_2_1.msg import SensorPacket ImportError: No module named irobot_create_2_1.msg
Thanks
Other threads have brought to my attention that I accidentally pulled both the Makefile and rosdep.yaml from the irobot_create_2_1 repo when doing some other maintenance work.I believe this is your problem (and why the older package release solved it for winterhater). This has been corrected both in the repo and in our newer package releases (though these of course take time to catch up). In the meantime, you can pull a fresh copy from the repo:
svn co https://brown-ros-pkg.googlecode.com/svn/trunk/experimental/irobot_create_2_1 irobot_create_2_1
or you can download the individually missing files: Makefile and rosdep.yaml .
My sincere apologies. This was really bone-headed and I will spend the requisite time on the wheel.

I have found the problem. It is because the first time i downloaded the brown drivers for irobot i did not have all the dependencies . But i run this command again
sudo aptitude install ros-diamondback-brown-drivers
it completed its dependencies . I do not know why at first time it did not get all the files while installing. But while it did not work , rosmake was successful but there was no makefile in the package. Now there is as supposed to be. Now it works.
