OpenVibe on Olinuxino

Post by luighi »

Hello to all. :)
It is possible to execute OpenVibe on Olinuxino or on another Olimex product?
thanks

Honestly, I have no idea, but if you can run Fedora or Ubuntu on it, compile Ogre/GTK with it, and get some EEG drivers going too, thats a very promising start. We'd be interested to hear how the rest goes. The only Linuxes we are officially supporting are Fedora and Ubuntu (with some dev going on on Mint).

What would you run on Olinuxino? The acquisition server? Designer? The whole deal?


My 0.2 cents,
Jussi

Hi jlindgren.
I'm a beginner, so excuse me if my question is a little too general: I would like to use the motor imagery signals (detected by an EEG that I'm building (not yet finished) similar to modularEEG) to drive a rover 2WD (even just start / stop ) on which it is housed olinuxino A13 wifi (on which runs ubuntu,please check this post: https://www.olimex.com/forum/index.php?topic=537.0.) [I also have an arduino2, a motor driver, motors, etc. ..]

Basically my goal is to replicate the experiment of motor imagery that is on the video presentation of openvibe, but carry it in a "physical environment".
Is it possible to use openvibe in this way?
How would I change Ubuntu and openvibe to have a minimum configuration suits my purpose?

I know that probably there is a lot of work to do and that the question isn't exactly easy but I would like to have only a guideline, a summary list of things to know (or learn) :D

[sorry for my english]

thanks

Hi, that sounds definitely a cool project to me! Just to be clear about it, by Rover do you mean

http://www.robotshop.com/dagu-rover-5-2 ... assis.html

or something like

If its the latter, I'd be very very careful before letting BCI drive it! If its the first, then I suppose it could be difficult to get a brain on board such a small platform to read EEG from. In the latter case you could use OpenViBE on a regular remote computer and then send just the commands extracted by OpenViBE to the target system over WIFI. So you wouldn't have the actual EEG processing on board the rover or Linuxino, just the logic that drives the vehicle according to the received commands.


Cheers,
Jussi

loooool :lol: :lol: :lol:

Really I meant this http://www.nasa.gov/mission_pages/msl/m ... 14175.html :mrgreen:

No, of course I meant a simple robot rover (this exactly http://www.robot-domestici.it/joomla/co ... ginner-kit)
I was hoping to "lighten" both ubuntu and openvibe in order to only use the scenario corresponding to the motor imagery.
However, how can I send the commands extracted by OpenViBE to the target system over WIFI? maybe with VRPN ?

In principle you should be able to run the processing and BCI data-acquisition on a desktop computer or a laptop, and direct the output to a VRPN server box in OpenViBE. Then, on the remote mobile platform, you'd have just to get a VRPN client working, and make it connect to the computer where you have the server (you have tcp/ip from the wifi?). The VRPN project page ( http://www.cs.unc.edu/Research/vrpn/ ) mentions they've been able to compile the vrpn client on various machines, so it could very well be doable.


Cheers,
Jussi
