Tiny Helicopter Piloted By Human Thoughts
- killing_time 13y agoWhatever you do, don't think about getting hit in the face by a helicopter...
- blutack 13y agoIt's a Parrot ArDrone quadrotor. The frame is made of foam which encloses the rotors and the motors automatically cut off if they sense the blades are obstructed. Being hit by one is like being bumped with a bit of polystyrene.
- droz 13y agoWired ran a story last year on a Chinese team that did the same thing already: http://www.wired.com/gadgetlab/2012/08/zhejiang-university-china-brain-controlled-quadcopter/ http://www.wired.com/gadgetlab/2012/08/zhejiang-university-c...
- curiousducky 13y agothey mentioned that in the article
- curiousducky 13y agoHow many directions can EEG control. If this is just up and down based on your level of concentration, it is relatively useless. However, if it maps all 6 directions, it is pretty impressive.
- DigitalJack 13y agoSeems like a good candidate for machine learning. Train a neuralnet to recognize the EEG patterns that a given person wants to use to do a given operation. For example, this one was having the subject think about making a fist, but it could be that having them "will" the copter to move right could be more intuitive. And with the right machine learning/recognizer it might be feasible. This would be a serious amount of fun to work on.

- btilly 13y agoIf you read the article, they have 2 signals, one corresponding to what you're imagining your right hand doing, one to what your left is doing. With this you have turn left, turn right, and both together is turn up. To really fly it you need another control for speed. (They just made the speed constant.)
- r0s 13y agoFrom what I know of existing EEG technology, the news here is left-right signaling, rather than simple on/off. Fascinating and cool as hell, but really limited for HCI applications.
- JackpotDen 13y agothe articles say 4 directions, but I'm going to assume that's because it's what they've been able to find clear enough patterns to map actions to. If they thought up a few more, ex "think about kicking your left leg" to move forwards, it could probably work. The leader talked about using wheelchairs and prosthetic limbs.
- zsombor 13y agoDownscaling the myriad of signals from your brain to 64 electrodes controlling four spacial dimensions seems tricky. I can see that making a fist may turn left, but what prevents any other random thought of being interpreted in the same way? I.e. how safe is a bike that turns left upon twisting the handlebars left, you may end up turning right with odds of 1:1000?

- vishaldpatel 13y agoIt would be interesting to learn how they account for: "No, not that way, I was just kidding."
