https://i.stack.imgur.com/lYFSq.jpg I am trying to set up ROS and Gazebo in a VM running Ubuntu. The goal is that I want to simulate Turtlebot with the open manipulator.

I installed everything without any issues. Though I am not able to launch the Turtlebot environment on Gazebo (like here: http://emanual.robotis.com/docs/en/platform/turtlebot3/simulation/)

$roslaunch turtlebot3_fake turtlebot3_fake.launch results in Gazebo staying forever in the state loading your world. After some time, it stops responding. Launching the empty world however works.

I am using ROS 1 with Gazebo 7.0

My hardware setup: MacBook Pro 13" 2019 with 16 GB RAM Parallels VM: 3D virtual. ON, no performance limit, 4 CPU kernels, 12 GB RAM enabled

Thank you so much for your help.

After every change you made source your bash and make sure to run :

          catkin make

if you've done this already then check if ros is installed properly by running 

           roscore

on one terminal and let it stay running. After that try to launch your turtlebot on another terminal. If it doesnt work even you have installed all of the needed things, i think the problem is with your VM, id recommend you to run ROS on Ubuntu running USB Stick.

  • I resloved it. Gazebo 7 wasn't compatible with my graphics card on my mac it seems. I decided to go with Ros 2 and Gazebo 9 and it worked perfectly then – Mystic Muffin May 07 '20 at 14:17

wget http://file.ncnynl.com/ros/gazebo_models.txt
wget -i gazebo_models.txt
ls model.tar.g* | xargs -n1 tar xzvf
