# Using Pepper without Pepper in Choregraphe

This tutorial will show you how to use **Choregraphe** for prototyping applications for Pepper and NAO when it is impossible to have the robot physically.

**Choregraphe** is the official Simulator for Pepper and NAO robots. 

{% hint style="info" %}
You can **install Choregraphe 2.5.5 (recommended)** from the [<mark style="color:blue;">official web page</mark>](https://www.softbankrobotics.com/emea/en/support/pepper-naoqi-2-9/downloads-softwares) or **Choregraphe 2.4** using [<mark style="color:blue;">this link</mark>](https://bitbucket.org/enriquecoronadozu/nep-installers/downloads/choregraphe-suite-2.4.3.28-win32-setup.exe)
{% endhint %}

### Option 1

Open Choregraphe, select Connect to .. (see image 1), and select the virtual robot (if available).

### Option 2

After installing Choregraphe search and open **naoqi-bin.exe** file inside the bin folder in the installation path of Choregraphe (example C:\Program Files (x86)\Aldebaran\Choregraphe Suite 2.5\bin)

The program **naoqi-bin.exe**, will be used to simulate communication with a real robot.

Open Choregraphe and connect to port **9559** and the IP **127.0.0.1*****,*** such as is shown in the next image

{% hint style="warning" %}
When using the simulator, you can not be able to access the sensors of the robot. However, you can use this approach for testing robot motions and text-to-speech.
