LEDs can only make light, they do not receive anything.

if you mean the LED-like looking things left and right to the red Front-LED, they can only "see" if it is dark or if there is light; so they wont be able to se shapes or a real picture. so you won't be able to do a real navigation in any way with these parts.

try to search for "kamera" is the asuro board, there are a few tries to navigate the asuro with a camera.
