Brain-Controlled Toy Robots

Hi All,

A while back, I did a hack were I made a brain-controlled toy robot.  I thought that I posted about it here on the forums below, but I couldn't find it.  So, sorry about starting a new thread...

Well, over the weekend, I got to hook up with Joel and Conor from OpenBCI.  I got to share with them the brain-controlled robot.  It was pretty fun.

If you're interested, I've got some movies of them driving the robot with their brain waves. 


Sharing hacks is blast!

    Interesting link there to Neurogadget article, interview with Chip.

    In addition to sharing my brain-controlled robot with Joel and Conor for one-person operation, the three of us also took hacked the setup a bit to enable multiple people to work together to control one robot.  It's pretty fun.

    Joel and Conor and I extended this hack.  Now, five people can join together to brain-control toys...this time we used a swimming shark balloon instead of the little spider robots.  I think that the swimming shark is pretty cool.

    A very nice demonstration!

    I love the different multi-users applications you've shown on your blog -- it's both entertaining and eye opening :)

    (also I'm learning everyday, I thought that there was a difference between the various bias pins; after your hex bug post I wanted to connect several persons at the same time to the board, now I know that I won't need anymore my ugly adapter "many male pin / one female pin").

    There is a trend toward "hyperscanning" in BCI, my guess is that OpenBCI could make it way cheaper. I have in mind an example with g.tec and P300 speller: 

    Next step for your experiments: ERPs? ;)

    Regarding the bias pins and your home-made adapter...

    On the 16-chan OpenBCI unit, all four bias pins should be producing the same signal.  So, for the bias, there's no home-made adapter necessary.

    But, for the SRB pins, the SRB pins on the daisy board are not connected in any way to the SRB on the main board.  So, if you want to use the same SRB reference for both boards, you will need your home-made adapter.

    Regarding the "hyperscanning", I'd never heard of that before.  Thanks for the link!
