Robot Hand Beats You At Rock, Paper, Scissors 100% of the Time
wasimkadak writes "This robot hand will play a game of rock, paper, scissors with you. Sounds like fun, right? Not so much, because this particular robot wins every. Single. Time. It only takes a single millisecond for the robot to recognize what shape your hand is in, and just a few more for it to make the shape that beats you, but it all happens so fast that it's more or less impossible to tell that the robot is waiting until you commit yourself before it makes its move, allowing it to win 100% of the time."
I for one welcome our new robotic overlords.
But to truly test it you have to add lizard and spock
So it cheats.
Can it beat Sheldon at rock, paper, lizard, spock, scissors? ;)
But what if we add lizzard and Spock into the equation?
This is really simple to do from a technical point so what's the merit? They found have made a cheating robot able to win a stupid game?
The whole point of RPS is that you don't know what choice your opponent will make, you are just guessing against their patterns. Looking at the other players hand is considered cheating. I wonder how often it would win with blinders put over it's camera.
already been tested 10^36 so it won't observe me. I've got too many hand movements to beat this.
Still waiting on Serviscope_minor to wake up to fucking reality and realize that Jessica Price isn't going to fuck him.
I for one, welcome our overlords in rock, paper and scissors :)
Is within sight. Next year Michael Bay will make this into a movie where everything explodes and there's no plot, and humanity will be complete.
Here is the original article, excerpt: "Recognition of human hand can be performed at 1ms with a high-speed vision, and the position and the shape of the human hand are recognized. The wrist joint angle of the robot hand is controlled based on the position of the human hand."
Here is a link to a video showing what it can do.
And now, the obligatory comment: I, for one, welcome our robotic rock-paper-scissors-playing overlords.

Good ol' rock. Nothing beats that!
What if you moved without trying to observe it, like quickly open your hand like paper as your hand comes down, then immediately close it into a fist?
Being faster? That's just cheating. On reading the headline, I thought they had developed an algorithm that predicted your next move, which would have been much more impressive. You DO get a ~40% improved chance of winning with this strategy:
When your opponent loses, his next move will be to beat whatever your move was on that round.
move 1) opp: rock you: paper # opponent loses to paper, so his next move will be to win over paper
move 2) opp: scissors you: rock # opponent loses to rock, so his next move will be to win over rock
move 3) opp: paper you: scissors # opponent loses to scissors, so his next move will be to win over scissors
etc.
It's self-reinforcing because after losing several throws in a row, opp becomes frustrated and less analytical, making it harder for them to see the pattern they are developing. :)
But that isn't absolute prediction, that's just playing on your opponent's human instinct. The robot hand isn't predicting anything.
Not just answers, the correct questions.
Complete rules for robohand v. human rock, paper, scissors:
Robohand crush rock.
Robohand bend scissors.
Robo-laser burn paper.
Puny humans no match for robohand.
In a survey of 100 programmers, 111111 thought that duck-typing was a good idea.
Is it any good at rock-paper-scissors-lizard-spock ?
Ho! Haha! Guard! Turn! Parry! Dodge! Spin! Ha! Thrust!
now more people will realise my secret superpower.... high speed vision...and the others at the Academy mocked me!

Firefox and Opera crash when trying to watch this video (adobe flash player plugin 100% cpu usage).
What about HTML 5?
So that we can make them compete and find out what happens.
Wonder what it would do against a trembling Alzheimer patient.

Hmmm, wondering how it would react if somebody flipped the middle finger at it
So the robot wins by imperceptibly cheating. The task, then, is to prove that the robot is cheating.
Start forming one shape, then deliberately and slowly turn it into another - if the robot changes its answer, it is clearly caught cheating, and does not win that round. Yeah, maybe you are cheating on that round too, but what does that matter? The claim was that the robot wins "100% of the time", which is now proven wrong.
(And if rounds where either side cheats simply do not count, then the robot is playing no valid rounds at all, so never wins.)
tl;dr if cheating is winning, then I win by throwing a brick at the robot.
of the robot hand, I think I could use this as an extension of my fleshlight.

The only winning move is not to play.
I once participated in a Rock-Paper-Scissors tournament put on by Epson (see, for example, http://www.campuslogix.com/rps_challenge/rps_challenge.html). They basically said "write a bot that will play RPS". Of course, the game-theoretic optimal strategy in such a contest is to just play randomly. You can beat the (Epson-supplied) rockbots and rotatebots easily, so with a bit of work you can do slightly above average.
Seeking a greater advantage, though, I coded my bot to also include a set of predictors for the random number generators for several popular libcs (as I did not which OS or distro the tournament machine would use). During a round, I would guess the random seed (current system time +/- a few seconds), the sequence offset, RNG processing strategy, and the algorithm used, and simply run a parallel copy of the libc RNG used by my opponent.
I was therefore able to beat most RNG-using opponents 9998/10000 times easily, a finding which rather surprised the judges :) I didn't win top prize (algorithm wasn't fast enough, and it turns out that was weighted more heavily than I expected), but I did get a high ranking and a cash prize.
Goes to show: sometimes a bit of "cheating" works well.
What would happen to the robot when faced with a mirror? Assuming you could get it to start playing.
Let's see if it can beat a person that has no hands.

By using the "atomic bomb" symbol, which vaporizes everything. I cannot show you the gesture here, because my ASCII art is too bad, but it involves symbolizing a glittering mushroom cloud with your open hand.
Could you develop a feint move that looks as though you are going for one thing but actually going for the other?
I for one welcome our new robohand overlords.
... that the human never picks scissors more than once.

It is so good at cheating that it is going into politics. That way it can brush up on the other important things like lying, stealing, and abusing power!
Think this was inspired by an old Hunter X Hunter chapter? http://www.batoto.net/read/_/20761/hunter-x-hunter_ch131_by_no-group/14
The correct title is:
Robot Hand Cheats You At Rock, Paper, Scissors 100% of the Time
If I waited to see what form the other persons hand is. Duh.
Maybe men can find a better use for a robotic hand that's dextrous and fast enough for rock-paper-scissors? If Howard Wolowitz had one of these, maybe he could've avoided that embarrassing hospital trip?
That was Transformers 3.
1. Rock crushes scissors 2. Scissors cut paper 3. Paper covers rock 4. Human smashes robot
try beating me with your power turned off
You try playing after having not eaten for days.
This large electomagnet not it's not significant
You try playing while someone's standing on your arm.
The computer virus, not important, I win again ....?
You try playing with the flu.
What happens if we set two of those robots to fight?
Seriously, now that robots beat us in every significant ability (this one was the last missing) we can't control the future anymore.

So what happens if two of them are playing each other??

Except when you're a Wookiee, then *you* win 100% of the time (provided the 'robot' is able to understand the arm will be ripped out of its socket and implement a new strategy).

Lisa: Look, there's only one way to settle this. Rock-paper-scissors.
Lisa's brain: Poor predictable Bart. Always takes `rock'.
Bart's brain: Good ol' `rock'. Nuthin' beats that!
Bart: Rock!
Lisa: Paper.
Bart: D'oh!
"But sir, nobody worries about upsetting a droid."
"That's 'cause droids don't pull people's arms out of their sockets when they lose. Wookiees are known to do that."
A robot arm wrestler will win every time also, and is much more fun to watch.

Now, robots can cheat. Great. They become more human all the time. Next step is: Lying in general, sueing, and playing with their ... ;-)
My scissors will cut the power cord which feeds electrical power to
the robotic hand.
Take that, you soul-less robotic bitch.
By the way, the above is a joke but the truth is that humans are incredibly adaptable,
and this will make it exceedingly hard to build a robot which will beat all humans all the time.
And once your robots have been beaten, I will eat your brains.
Just change the rules. Silly specialized system adaptation is for humans.
"Human-machine cooperation" as in "How about you let me win every time, puny human."
You are incompatible. You shall be DELETED.
*pulls power* A-ha now I win 100% of the time!
