Try to get turtlebot running failed (need help)

Hello All,

I am trying to get the turtlebot Project (Simulator) running on my system, but I do not get it to run.

I have done the following steps:

1) Create a own workspace with
$mkdir -p ~/turtlebot_ws/src

2) Run catkin_make in ~/turtlebot_ws/
$catkin_make

get the folder

build
devel

3) Add the following line into my ./bashrc

// needed to get gazepo run in VMware
export SVGA_VGPU10=0
echo export SVGA_VGPU10=0

// needed for the base installation of ROS
source /opt/ros/kinetic/setup.bash
echo source /opt/ros/kinetic/setup.bash
echo open “.bashrc” to modify the active ROS project

// for the beginner project needed
//cd ~/catkin_ws
//source devel/setup.bash
//roscd beginner_tutorials

// for the Turtlebot project needed
cd ~/turtlebot_ws
source devel/setup.bash

4) Check the ROS variables and get the following result
$ printenv | grep ROS

ROS_ROOT=/opt/ros/kinetic/share/ros
ROS_PACKAGE_PATH=/home/ros/turtlebot_ws/src:/opt/ros/kinetic/share
ROS_MASTER_URI=http://localhost:11311
ROSLISP_PACKAGE_DIRECTORIES=/home/ros/turtlebot_ws/devel/share/common-lisp
ROS_DISTRO=kinetic
ROS_ETC_DIR=/opt/ros/kinetic/etc/ros

5) get the turtlebot project from git
$~/turtlebot_ws$ git clone https://github.com/turtlebot/turtlebot.git

6) Try to run the simulation
$~/turtlebot_ws$roslaunch turtlebot_gazebo turtlebot_world.launch
get the follwoing error message
[turtlebot_world.launch] is neither a launch file in package [turtlebot_gazebo] nor is [turtlebot_gazebo] a launch file name
The traceback for the exception was written to the log file

7) Run the Check installation tool "roswtf"
an get the following result:

Loaded plugin tf.tfwtf
No package or stack in context

Static checks summary:

No errors or warnings

Beginning tests of your ROS graph. These may take awhile…

Online checks summary:

Found 1 warning(s).
Warnings are things that may be just fine, but are sometimes at fault

WARNING The following node subscriptions are unconnected:

Can somebody help me to fix this. Maybe I have forgot something.

I have to admit, I am new in ROS, but I have already read and execute the beginner_tutorials,
which has worked fine for me.

Best regards
Ritchie

Hi Ritchie,

Thanks for the detailed question. However we ask for debugging questions on http://answers.ros.org That’s a website optimized to get you your answers whereas discourse is focused on announcements and discussions.

Please reask your question there.

Having read your post, here are some tips to improve your question. Please check that you’re putting the turtlebot source in the src subfolder of your workspace. And be sure to build after you checkout the source. Also you don’t appear to be checking out the turtlebot_simulator repository which has the turtlebot_gazebo package. You may also want to look at the output of rospack list.

I’d also suggest that for getting the demo running you simply use the binary debian packages instead of trying to build it from source. You can just apt-get install ros-kinetic-turtlebot-simuator and the whole demo will be installed.
