Almost any electronic shop has IR leds and some TSOP receivers from Vishay.
If not, ebay is a good place to start.

im working on a robot design.

its a 4wheeled platform (remote controlled), but i want to put a camera or somthin on the front so i can "see what it sees"
similar to the spy gears video car

but the problem is that i dont know where to start with this camera or how to set it up or how i can get the feedback

and i also want to kno the avr. cost of the camera setup

This (http://www.sparkfun.com/commerce/product_info.php?products_id=616) is what you want.
You plug it in a TV, tv tuner card or portable player and there you go, instant camera.

Of course, it's the worst choice for image processing, but then again, that's not a beginner topic.

I have that same camera and just mounted it on a rover I built. It has an ok picture but its range is very limited.

I also have one

Maximum of 100 ft. range for me - it depends on the surroundings also

Heh, I assumed you wanted a low cost solution since you were asking about the cost. The camera I mentioned is indeed a low cost solution, cheapest I know of. Range isn't very good, I haven't been able to go past two walls indoors. Image quality also suffers (at some point when camera battery was running low, I got only b/w images).

If you would like something of higher quality, a CMOS camera would be much better suited. Of course, there's still the problem of transmitting and encoding that data.
