Cheat the cheater?
Wonder whether this would work or does the robot adjust itself again and again?
No matter how many John-Wayne-inspired moments you've had in front of the mirror, you're not as quick on the draw as the Janken robot. Ishikawa Oku Laboratory in Tokyo has built the android to have a perfect score at rock-paper-scissors, identifying which way its human opponent is going to go in one millisecond. The boffins …
To answer your question more correctly, what you're looking at isn't Buridan's Donkey (which is the problem of choosing between two options an equal distance apart and being frozen with indecision). Rather it looks like you're trying to start a classic deadlock. A device is dependent on an input, but connect two such devices to each other, and neither of them does anything because each is waiting on the other to act.
how does that work? there's nothing in the rules that says paper has to be shown as palm up, or that rock is anything more than a clenched fist - you can have your hand horizontal (so your wrist would be the same as if showing paper with palm down) or vertical and so wrist is in same orientation as scissors.
In fact, no reason why paper has to be shown horizontally either.
(is this explained in the video? it's blocked by the office firewalls)
DOCTOR: Scissors cuts paper. Ha, ha! But suppose we were two computers controlling two great battle fleets, each one working perfectly logically to outmanoeuvre the other. Well, you're robots, you try it.
SHARREL: We're perfectly
DOCTOR: Try it! Go on.
(The two Movellans come up with scissors and scissors twice, then stone and stone.)
DOCTOR: Ha! You see? You're caught in an impasse of logic. You've discovered the recipe for everlasting peace. Congratulations. I'm terribly pleased.

Of course the robot is actually cheating,if you watch the last slow mo decision in the video its waiting till the human finishes making a gesture before performing its own and even I can do that.
