TODO: Build a robot with precise enough control that it can flip a coin (properly flipping, not just wobbling) and then catch it in a desired state (either heads or tails) with substantial accuracy.

That reminds me of the rock-paper-scissors robot from a while ago that always "wins" by watching the human hand to see what sign they are throwing, then throwing the countersign faster. It is so fast that unless you are watching it on high-speed film, you can't tell that it is cheating.

Not a robot, but Persi Diaconis (mathematician and magician) built a coin-flipping machine.
