One design for a 4-way flip-flop chip in Robot Odyssey. This is a flip-flop that has four inputs and four outputs. When one input is on, its corresponding output turns on and all others turn off. This chip can be the basis for lots of interesting robot motion circuits, including the Wall Hugger.
This design uses a positive edge detector (the AND and NOT gate in the middle) to reset the other flip flops. Without this circuit, the 'off' signal at the output flip-flops would still be high even after the 'on' signal has disappeared, so the flip-flop would not latch. Another alternative would be to add a two-gate propagation delay to the 'on' signals, so they don't disappear too early. This method has lower latency than that approach: The 'on' signal appears with no extra gate delay.
Very good. Dunno what I could use it for, but I have a soft spot for Robot Odyssey/Droidquest vids. I need to get to work on making a Robot Odyssey vid of my own!
