Hello
I just received my Turtlebot 2/Kubiki base. It comes with Groovy pre-installed in the ASUS Laptop. I wanted to start the two demo applications
So, I did
roslaunch turtlebot_teleop keyboard_teleop.launch
and roslaunch turtlebot_follower follower.launch As in Tutorial, I opened an ssh from my PC and run the launch files.
For "roslaunch turtlebot_teleop keyboard_teleop.launch" I get the following error:
IOError: Errno 13 Permission denied: '/home/turtlebot/.ros/rosdep/sources.cache/index'
[turtlebot_teleop_keyboard-1] process has died [pid 22131, exit code 1, cmd /opt/ros/groovy/stacks/turtlebot_apps/turtlebot_teleop/scripts/turtlebot_teleop_key turtlebot_teleop_keyboard/cmd_vel:=cmd_vel_mux/input/teleop __name:=turtlebot_teleop_keyboard __log:=/home/turtlebot/.ros/log/f6daa71c-7692-11e2-8049-446d57c5292a/turtlebot_teleop_keyboard-1.log].

and for "roslaunch turtlebot_follower follower.launch" I get the following error:

Any help?

What user do you use for ssh?
Comment by Anis on 2013-02-14:
I used "ssh turtlebot@IP_ADDRESS_TURTLEBOT" I also executed the demo from turtlebot itsefl and the same problem occurs

I used "ssh turtlebot@IP_ADDRESS_TURTLEBOT"

That should be correct. I don't know how their default image is set up. A fix might be to re-run sudo rosdep init, rosdep update, but maybe it's supposed to work differently, so I don't give any guarantees that this doesn't interfere somewhere else.

Can you teleop from the Turtlebot Laptop? If yes, then it is connection problem. If not, then it is ROS problem.

exactly the same problem happened to me, could you give me a hint about what should I do?
