[[Tutorial for ver.3]]

Virtual robots can be controlled by using SIGVerse and ROS (Robot Operating System).

This section describes examples using ROS.
For the examples which do not requires ROS, please see [[here>Tutorial for ver.3]].

* System Requirements [#SystemRequirements]

If you want to use ROS, prepare an Ubuntu environment and install ROS there. ~
ROS communicates with Unity on Windows. ~

The requirements for Windows can be found at [[here>Tutorial for ver.3#SystemRequirements]].

The ROS requirement is that the OS is ''Ubuntu 20.04'' and ROS [[Distribution>http://wiki.ros.org/Distributions]] is ''Noetic Ninjemys''.

* Environment Setup[#vf01a3c9]
* Build Windows Environment [#k2704bce]

** Build Windows Environment [#k2704bce]

Please refer to [[here>Tutorial for ver.3#SystemRequirements]] to build the Windows environment.~
After that, please build the following environment.

** Build Ubuntu Environment [#zddcd2d8]
* Build Ubuntu Environment [#zddcd2d8]

Build Ubuntu environment as follows.~

*** Using VMware [#gc586877]
** Using VMware [#gc586877]

Instead of preparing an Ubuntu PC, you can use an Ubuntu virtual machine on Windows. ~
However, in this case, it will be difficult to run tutorials using the GPU. ~
Also note that using VMware requires a lot of computational resources.
Also note that using VMware requires a lot of computational resources. ~
And the Docker may have problems coexisting with VMware. Please note this.

The procedure for building an Ubuntu environment using VMware is as follows.

+ Download VMware Workstation Player.~
https://my.vmware.com/web/vmware/downloads/info/slug/desktop_end_user_computing/vmware_workstation_player/16_0
+ Download Iso file of Ubuntu 20.04.3 LTS.~
+ Download Iso file of Ubuntu 20.04.4 LTS.~
http://releases.ubuntu.com/focal/
+ Launch VMware Workstation Player.
+ Click [Create a New Virtual Machine].
+ Use [Installer disc image file(iso):] and select ubuntu-20.04.3-desktop-amd64.iso.
+ Use [Installer disc image file(iso):] and select ubuntu-20.04.4-desktop-amd64.iso.
+ Recommend to check "Store virtual disk as a single file" on Specify Disk Capacity window.
+ After you have finished creating the VM, adjust the memory and processors in the Virtual Machine Settings of VMware Workstation Player.~
And also set the settings to use the Enhanced keyboard.




*** Install ROS Noetic Ninjemys [#dccef8ca]
** Install ROS Noetic Ninjemys [#dccef8ca]
Run [[the ROS Installation page>http://wiki.ros.org/noetic/Installation/Ubuntu]] up to section 1.6 to install ROS. ~
Then follow chapter 3 of the [[ROS tutorial>http://wiki.ros.org/ROS/Tutorials/InstallingandConfiguringROSEnvironment]] to create a ROS workspace.

And add "~/catkin_ws/devel/setup.bash" to .bashrc to simplify subsequent commands. Be careful if you manage multiple ROS workspaces.

** Installation of required libraries (using shell scripts) [#b2d24795]
The following is a procedure for batch installation of libraries using a shell script. ~
If this procedure is performed, the subsequent manual installation steps are not necessary. ~
We have confirmed the operation with the standard installation of ROS Noetic. ~
Therefore, if the name of the ROS workspace is not catkin_ws, it will not install properly. ~
Please use with caution.
 $ wget https://raw.githubusercontent.com/SIGVerse/docker-ros/main/noetic/sigverse_setup.sh
 $ chmod +x sigverse_setup.sh
 $ ./sigverse_setup.sh
 $ source ~/.bashrc


** Installation of required libraries (manual) [#jbcea028]

*** Add commands to .bashrc. [#rc7a2078]
Add "~/catkin_ws/devel/setup.bash" to .bashrc to simplify subsequent commands. ~
Be careful if you manage multiple ROS workspaces.

 $ echo "source ~/catkin_ws/devel/setup.bash" >> ~/.bashrc
 $ source ~/.bashrc

* Execute Example Scenes with ROS [#o023aef1]

** Unity Scene Execution [#open_scene]

Before running the Unity example scene, you need to set the IP address for ROS on Unity.

+ Check the IP address of the Ubuntu side. ~
Execute the following command in Ubuntu side to check the IP address.
  $ hostname -I
+ Open the SIGVerse project in Unity.
+ Click [SIGVerse]-[SIGVerse Settings] in the Unity menu to open the SIGVerse settings window.
+ Enter the IP address of Ubuntu side in [Config file Settings]-[Rosbridge IP]. ~
(You can also change [Rosbridge Port] and [SIGVerse Bridge Port] in the same way.)

#ref(SIGVerseSettings.png)


The Unity scene is executed as follows:
+ Double-click [Assets/SIGVerse/ExampleScenes/xxxxx/yyyyy(.unity)] on the [Project] tab to open the target scene.
+ Click the play button at the top center of the Unity to play the scene.
