Imagine Braintenberg vehicles, unable to compute XOR. One is an AND gate that lifts the wheels of a thing off the ground, the other an OR gate that gets them moving. When nothings ON nothing happens. When the OR gate opens the thing moves. But when both gates open the wheels move but they also get lifted off the ground so the thing doesn’t move. So the whole thing computes XOR!
