Okay so basically i have got part of this done but messed up scrapped it and started it is for my robot but requires alot of different things so it's not actual robotics in this post but constructing an eklectronic device. I need to make a small device which has 5 infared sensors and when the sensors get within 3 feet of something it will send a signal to i guess a microcontroller which will trigger sound 1 if it is from sensor 1 and so on... Is this possible if so what sensors do i use and what microcontroller or whatever it's called. I got the idea but not sure i will probably need some pic programming won't I?

I doubt whether you will get a 3 feet detection rang using infrared detectors. You could try an ultrasonic ranging system these have a much greater detection range than IR.
Thats the same idea used in some older type Polariod cameras. Heres a link with some info on those.
