I recall seeing a news story on TV many moons ago about a device that enabled a person to move a mouse cursor around a computer monitor using only brain waves. Google "brain wave mouse" and you'll find a bunch of articles on this topic. It would be quite a fun project to see if a FIRST team could use this technology to *safely* and *effectively* control their robot. Talk about an attention getter if they succeeded!
As teams discover new and creative ways to control their robots, I hope the game design committee will eventually adjust their operator interface rules to safely accomodate such inventiveness. I have a feeling they'll come through.
