Actually, LEDs can detect light as well as emit light. It could make your bots simpler hardware-wise to use the LEDs as input devices between blinks.
I bought some relatively cheap and bright yellow LEDs (OVLGY0C9B9) rated at 20000 mcd. I was easily able to detect one of them shining at another one from a distance of 12 inches. I had to be pretty accurate aiming it, which might be a good thing for your project. The green and blue ones are even brighter.
