All of the tutorials starting with 1 worked fine, but I get into trouble when doing 2.1. I'm able to start the URDF Asset importer, and it looks like everything is importing fine when pressing the **Read Robot Description.** button, but...\r\n1.  When it's done I'm getting a prompt saying **Do you want to generate a null GameObject now?**\r\n![unity_nullobject](https://user-images.githubusercontent.com/10755449/38853265-0261b066-421d-11e8-8a24-b84ae72a918f.PNG)\r\n2.  The imported **null** GameObject looks like the TurtleBot, but the buttom (Kobuki) part is turned 90 degrees around the x axis, making it look like a wheel.\r\n![unity_robot](https://user-images.githubusercontent.com/10755449/38853264-0247eac8-421d-11e8-8bff-f9e00dd3d125.PNG)\r\n3.  In the Unity console I get a few warnings of the type \r\n```No Joint Component will be created in GameObject \"camera_[xxx]_frame\" as it has no Rigidbody Component. Please define an Inertial for Link \"camera_depth_optical_frame\" in the URDF file to create a Rigidbody Component.```.\r\nWhere [xxx] is `rgb`, `rgb_optical`, `depth` or `depth_optical`.\r\n![unity_console](https://user-images.githubusercontent.com/10755449/38853324-30887740-421d-11e8-8590-a576bfe42249.PNG)\r\n4.  When trying to import the .unity scene from step 2.2 (`GazeboSimulationScene.unity`) by doing **File -> Open Scene**, nothing happens. I found the scene in `ros-sharp/Unity3D/Assets/RosSharp/Scenes/GazeboSimulationScene.unity` since the latest Release (linked to in the tutorial) does not contain it.\r\n5.  I tried doing the scene manually, as described in the same tutorial, and it seemed to work fine. But when starting the **gazebo-simulation-scene** on the Ubuntu VM I get the following error in the terminal: `ERROR: cannot launch node of type [gazebo_simulation_scene/joy_to_twist.py]: can't locate node [joy_to_twist.py] in package [gazebo_simulation_scene]`, and the Gazebo main Window just remains black. I can start Gazebo normally and it seems to work fine.\r\n\r\n* My OS is: Windows 10 Pro, version 10.0.16299\r\n* My Unity Version is: 2017.3.1f1\r\n* My Ubuntu (on VirtualBox) Version is: 16.04\r\n* My ROS Distribution is: Kinetic\r\n* My Gazebo version is: 7.12.0 (the one on the ORDF repository).\r\n\r\nThanks in advance, this seems like a great product otherwise and I'm excited to get going :)"},"comment":{"url":"https://api.github.com/repos/siemens/ros-sharp/issues/comments/382622690","html_url":"https://github.com/siemens/ros-sharp/issues/47#issuecomment-382622690","issue_url":"https://api.github.com/repos/siemens/ros-sharp/issues/47","id":382622690,"user":{"login":"hassanbot","id":10755449,"avatar_url":"https://avatars1.githubusercontent.com/u/10755449?v=4","gravatar_id":"","url":"https://api.github.com/users/hassanbot","html_url":"https://github.com/hassanbot","followers_url":"https://api.github.com/users/hassanbot/followers","following_url":"https://api.github.com/users/hassanbot/following{/other_user}","gists_url":"https://api.github.com/users/hassanbot/gists{/gist_id}","starred_url":"https://api.github.com/users/hassanbot/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/hassanbot/subscriptions","organizations_url":"https://api.github.com/users/hassanbot/orgs","repos_url":"https://api.github.com/users/hassanbot/repos","events_url":"https://api.github.com/users/hassanbot/events{/privacy}","received_events_url":"https://api.github.com/users/hassanbot/received_events","type":"User","site_admin":false},"created_at":"2018-04-19T06:15:40Z","updated_at":"2018-04-19T06:15:40Z","author_association":"NONE","body":"**Concerning 2**:\r\nYes, it now seems to be working correctly!\r\n\r\n**Concerning 5**:\r\nGreat!\r\n\r\nI'm closing this issue now since all sub-issues have been solved.
