Hi, i would like to ask about circuit u use in robocon 2007 this year, as u see the line is white and the background is blue .. and how do you recover ur sensors from noise and ambient light ? and do u use circuits like Compartor with a variable resistor and pair of photo transistor and IR led ?
thanks
