Error with kobuki_node minimal.launch

asked 2019-05-05 16:30:15 -0500

Hi,

I just follow this guideline to install kobuki packages for a ROS Kinetic (with Ubuntu 16.04 Xenial): http://wiki.ros.org/kobuki/Tutorials/Installation

The following command :

roslaunch kobuki_node minimal.launch --screen

produces this output :

ros@ros-computer:~$ roslaunch kobuki_node minimal.launch --screen
... logging to /home/ros/.ros/log/09378be6-6f7a-11e9-bace-dc85de56dbd7/roslaunch-ros-computer-3297.log

Any idea of the reason of this problem?

I've the same error if I install the turtlebot packages :

sudo apt-get install ros-kinetic-turtlebot ros-kinetic-turtlebot-apps ros-kinetic-turtlebot-interactions ros-kinetic-turtlebot-simulator ros-kinetic-kobuki-ftdi ros-kinetic-ar-track-alvar-msgs

Best regards,

Philippe
