Science Buddies: "Ask an Expert"

How would I go about creating a doll that could be controlled using an EEG headset?

Welcome to the forum. I moved your post to the Math and Computer Science forum because processing the signals and controlling the doll is a computer-science problem. Have you read about robotics in general? If it turns out that interpreting EEG signals is not a well-solved problem, you might also want some input from the experts who read the Life Sciences forum.

I have just begun research and robotics are one of the subtopics I am exploring and I will check out the life sciences forum as well.

You have two projects and either one would be a good stand-alone project. Do not get in over your head.

Project One:

Building and controlling a robotic doll is a major task. Build the doll and then create an interface with defined signals, their levels, interactions, imlementing the control signals, making it work as a controllable object. Do these and you have a winner.

Project Two:

Building an EEG that shows the various voltages is easy. The hard part extract the information you need from the background signals resulting from all the other brain activity. Isolating a single signal is a monumental effort in signal analysis. Do that alone and you will have a winner. If you can put a headband on someone and then have them turn a light on ond off by just thinking about it you will be in the top ten of all researchers world-wide. Forget the doll.

Thank you very much for these project ideas! I guess I was thinking a bit too big for a highschooler. I'll probably go with building a small robot that can walk and do something simple like picking up an object or something. I'll have to think deeper into that though.
