Hi everyone,

The kubuntu was already installed on laptop, so I installed ros-electric-turtlebot, ros-electric-ros and ros-electric-apps and I configured the networks settings. But when i type "sudo service turtlebot start" I get:

"start: Job failed to start". and when I type "sudo service turtlebot stop": "stop: Unknown instance:"

This error is shown when I try to use "roslaunch turtlebot_bringup robot.launch":

ERROR: cannot launch node of type [robot_pose_ekf/robot_pose_ekf]: Cannot locate installation of package robot_pose_ekf: [rospack] couldn't find package [robot_pose_ekf]. ROS_ROOT[/opt/ros/electric/ros] ROS_PACKAGE_PATH[/opt/ros/electric/stacks]


Also, when I use "roslaunch turtlebot_bringup minimal.launch", i get these errors:

[turtlebot_laptop_battery-4] process has died [pid 2985, exit code 1]. log files: /home/USERNAME/.ros/log/9db4292a-d59d-11e0-8222-74f06d20ce80/turtlebot_laptop_battery-4*.log


process[turtlebot_node-3]: started with pid [3147] Traceback (most recent call last): File "/opt/ros/electric/stacks/turtlebot/turtlebot_node/nodes/turtlebot_node.py", line 48, in import serial ImportError: No module named serial [turtlebot_node-3] process has died [pid 3147, exit code 1]. log files: /home/USERNAME/.ros/log/9db4292a-d59d-11e0-8222-74f06d20ce80/turtlebot_node-3*.log respawning...

Does anyone know how can I fix these errors?

Thanks in advance,

On your robot you should install ros-diamondback-turtlebot-robot. Currently the TurtleBot software is only stable on ROS diamondback.

On your workstation computer you should install ros-diamondback-turtlebot-desktop

If you have import errors similar to what is listed above then you are most likely missing rosdeps


rosdep install turtlebot
