Click the appropriate link for your system for V-REP PRO EDU V3.4.0

Unzip the file and you are good to go. Run it by running the vrep.sh script that it comes with. This can be done by navigating to the unzipped folder and running ./vrep.sh

After you install it there should be an exe you can use to run it

Instructions can be found here. Basically Python needs to know the location of three files (vrep.py, vrepConst.py and remoteApi.extension)

The first two are found in /path/to/vrep/programming/remoteApiBindings/python/python

The last file is in /path/to/vrep/programming/remoteApiBindings/lib/lib/

There is a 32 bit and 64 bit version of this file. I think it has to match with the version of Python you have installed. If one doesn't work, just try the other.

The easiest thing to do is to copy these files into the directory where you are running your Python scripts from. On Mac/Linux you can also just soft link them to your current directory with:

ln -s /path/to/file/filename.extension

If V-REP is extracted to your Downloads directory and you are currently in the directory with your code (e.g. robotics_simulator) you can set everything up with the following commands:

ln -s ~/Downloads/V-REP_PRO_EDU_V3_4_0_Linux/programming/remoteApiBindings/python/python/vrep.py . ln -s ~/Downloads/V-REP_PRO_EDU_V3_4_0_Linux/programming/remoteApiBindings/python/python/vrepConst.py . ln -s ~/Downloads/V-REP_PRO_EDU_V3_4_0_Linux/programming/remoteApiBindings/lib/lib/64Bit/remoteApi.so .

In some versions of V-REP the vrep.py file does a bad job of trying to find remoteApi.so. You'll see an error when importing vrep if this happens. To fix this, edit the vrep.py file and change one line (likely line 48) from:

libfullpath = os.path.join(os.path.dirname(__file__), 'remoteApi' + file_extension)

to:

libfullpath = './remoteApi' + file_extension

There is no explicit support for using V-REP with nengo_gui, it just happens to work (most of the time). With this in mind, there is a specific order of steps for running both simulators to ensure they play nice together.

1. Launch V-REP (./vrep.sh) and open the specific scene file of interest (my_scene.ttt).
2. Make sure the V-REP simulation is stopped (press the blue square).

• It defaults to this state when first opened.
• You may have to close your nengo script if it is open at this point.

3. Launch your nengo script with the gui (nengo my_script.py).

• When the script first opens it will establish a connection with V-REP and start the simulation (the blue triangle in V-REP will become pressed).
• Nothing in V-REP should be moving at this point, even though the simulation has started. This is because nengo has taken control of the time step.
• If you set the sync flag to False on the Robot object in python, things will move at this point, but it defaults to True.

4. You are good to go, press play in the nengo_gui and enjoy!

If something goes wrong, which can happen sometimes when editing the code live, repeat steps 2-4.
