Sorry for my English, I'm a Chinese.

First I should mention I'm a crazy model fan, and I only make hi detail models.

  I'm also a crazy fan of artificial intelligence and microelectronics. Rovio is a wonderful platform to do  some experiments, so I changed its shell as well as its inner circuit.

  I made a  electromagnetic valve and added it to rovio, the bottle on the right is filled with CF2ClBr(4ATM). Then I use adaboost+SVM to train rovio:

And then...rovio became an auto fire  extinguisher! Rovio is just wonderful!

I also wrote a rovio controller program with object tracking and motion detection. 

The code was written in C#.net 3.5 and soon I'll upload it here.

  A lot of people ask me how the "remote fire extinguisher facility" works. I'm sorry I didn't make it clear on the  above article. The fire extinguisher facility is connected to a optocoupler switch( I replaced the front light with an optocoupler switch). Since the current of the front light is only 8.9mA,I made a circuit which uses rovio's own battery to amplify the current. By doing so ,rovio can make the decision of turning on or turning off the switch itself.

 Now I'm trying to replace the W99802 and Marvell chip with Microsoft Ebox , it's a crazy idea but if this has been done successfully ,I can find partners to produce indoor fire extinguisher robots for commercial use since all the software and hardware are tested. One of my professors even said that  he would  invest 2×10^5 RMB to help me make a larger  rovio-like vehicle with a gun and sell this anti-terrorist robot (Auto?) to the police. I often laugh at those engineers who bought Su-27 and do some recreations, but now I'm doing the same thing!
