Science Buddies: "Ask an Expert"

Hello!
Can you help me how to build a things that can do anything using our mind.
It's like we think a drawing and the pencil will do what we have thought in our mind.
Can you explain the principal of this project?
Thank you..

I am not sure how you would make something that does that from scratch but there are a few games that do it. Maybe you could take one apart and repurpose it?
