I'm trying to run the 3dsensor.launch file for turtlebot, and I'm getting the following error message. Anybody know what might cause this? I'm running indigo on ubuntu trusty, and I built the turtlebot packages from source.

Thanks a bunch!

Actually I think I just got it to work! I had to reset the kobuki udev rules:

source ~/turtlebot/devel/setup.bash; rosrun kobuki_ftdi create_udev_rules

With each new shell login. Weird. But seems to work now.

Thanks! David

O .. K ..; that seems really weird. But if things work for you ..

This is weird. 3dsensor.launch does not associate with any kobuki udev rules...

Do you have the nodelet package installed?

I'm running indigo on ubuntu trusty, and I built the turtlebot packages from source.

Have you done a rosdep check .. on your src directory (or at least, the directory containing the turtlebot nodes)? That should show any missing dependencies.

Edit:

roscd nodelet goes to share/nodelet

and is there a nodelet binary in lib/nodelet?

As far as I can tell, nodelet is installed. roscd nodelet goes to share/nodelet, and apt-get install nodelet says its already newest. I ran rosdep check .. in turtlebot/src, and got:

ubuntu@ubuntu:~/turtlebot/src$ rosdep check nodelet All system dependencies have been satisified

And you don't have a nodelet pkg in your catkin_ws that is shadowing the 'official' nodelet pkg, but doesn't have a nodelet node in it? An overlayed nodelet pkg would make the official one 'invisible' to roslaunch.

gvdhoorn ( 2015-03-05 07:38:46 -0500 )edit

Also: there are indigo versions of the turtlebot packages, so you might want to look at those, instead of building from source (but that would not really solve your issue).

gvdhoorn ( 2015-03-05 07:39:52 -0500 )edit

Yeah I tried the pre-built turtlebot stuff but I'm running on a Raspberry Pi and some stuff is not supported on ARM (gazebo, in particular), so I had to filter out that stuff to make it work. And I don't see any reference to nodelet anywhere except the /opt/ros/indigo/share/nodelet directory

dfk ( 2015-03-05 07:58:14 -0500 )edit

So you don't have nodelet in lib/nodelet?

gvdhoorn ( 2015-03-05 08:02:07 -0500 )edit

I do have that. Sorry -- my bad before not mentioning it. There is /opt/ros/indigo/lib/nodelet

dfk ( 2015-03-05 12:37:01 -0500 )edit

And it contains an executable "nodelet"
