Have you been wanting to get into robot building, but found the whole endeavor too daunting? Fear not! You can start simply with ScooterBots! This kit contains everything you need to build cute little googly-eyed brush-bots that will happily scoot along any flat surface for hours. Experiment with leg and motor configurations to see which direction it will scoot.

HEEEEEELP!

I cannot figure out how to rig up a circuit for XNOR, 3input XOR or 3input NAND gates and this thing is due tuesday! No transistors, one  LED per gate example. It's just supposed to be a simulator for how logic gates work. I've figured out how to do AND, NOT, and OR. Can anyone help me? or link me somewhere helpful?
