back to article Russian ChessBot breaks child opponent's finger

A Russian chess robot has broken the finger of a child. The incident happened at a Moscow tournament on July 19, when a robotic arm that uses AI to help it play three games at once went rogue. Its antics went viral after video appeared in the Telegram post embedded below. There's no need to fear the rise of the machines, or …

    did anyone else have the thought 'Is the child Ukrainian?'

    Break their trigger fingers early so they can't fight later on. Hope the youngsters finger mends without any problems, and he / she continues playing chess into the future without and trauma from the incident.

    Questionable Explanation

    I find it hard to believe - or understand - the official explanation. The robot had just made its move and the human (child) supposedly played too quickly? What possible reason is there for the robot to grab the human's finger? Having made its move, it simply needed to retract its arm and wait to recognise the human having made their move. If anything, the human playing too quickly might conceivably make the robot not realise the human's move had been made, but certainly not to go all out into vindictive mode.

    Be worried.... very worried...

      I can think of no good reason why a chessbot needs to be able to grab anything at all.

      If I were designing it, it would work by moving magnets around beneath the board.

          Re: So how do you ... move a Knight?

          Or Castle the King, or move a Bishop or Queen diagonally past other pieces without disturbing them. Suggestion implies lack of pretty basic chess knowledge.

            Re: So how do you ... move a Knight?

            There were chess computers in the '80s which moved the pieces by themselves, so this has been done before. One way would be to make the pieces small relative to the squares so they fit past when moved diagonally. For castling, I think some of them moved the king off the board, out of the way, in order to do the move.

            Perhaps a more interesting question would be how does it accomplish a pawn promotion (possibly also including a capture on the promotion square)? Remember that the pawn can promote to something other than a queen if the game position suits such a move.

            Also interesting: en passant captures.

          These have actually been built, and use several approaches, most based on simply clearing the other pieces from the path and replacing them once the piece is cleared. There is plenty of room on a standard board.

          In the castling example it is not shifting much material as the castling rules are pretty restrictive, but if you are a chessboard masochist there are more tangled messes that could result from aggressive use of knights. That said I expect removing material from the board from regular captures is often probably more complicated. Clever work for the 80's-90's era example I remember.

          A less clever method, but more elegant in some ways would be to use a bigger board and smaller pieces, so there is space to drag them between the rows and ranks without resetting pieces.

      Re: Questionable Explanation

      It's a really grotty video. And doesn't make much sense.

      It looks like the robot removes the White Queen on D1. (Why?) The kid then moves the castle from its starting position to that square. It's look like he's still holding onto the piece (castling?) when the robot goes for his finger

      Speculation: the AI thinks the arm failed to pick up white queen and is re-attempting the move.

        Re: Questionable Explanation

        Speculation: the AI thinks the arm failed to pick up white queen and is re-attempting the move.

        It looked like that to me. I was wondering why, if it were doing that, it didn't keep doing that, lift the piece, finger and boy, and try and dump all in the tupperware box.

        A better quality video shows the arm had picked up a Bishop and was placing that where the boy had moved his Castle to. So more a crushing injury than a grabbing injury.

        Full marks to the observer who was heading for the Escape key as soon as the arm was returning to where the kid had placed his piece.

          Ahhh, yes; that makes sense. The kid's effectively gone, "don't bother putting that bishop down - my rook's going to feast on it." But, as good as the AI is at chess, it's useless at anticipating a rudimentary social interaction, even within the confines of a chess board.

      Robots move... takes queen with black bishop

      - picks up queen from the board - drops in container

      - picks up bishop and puts in on queens location

      During this move kids picks up castle and moves it to queens location. The robot had not finished its move so the puts the bishop down on his finger

          I was going to add something similar, along with torque limiting everything(*) and a stall sensor

          It doesn't NEED to have 500N force behind it to move pieces and an arm which can be stopped by anything substantial in its way is much safer than one which can't be, for the same reason you don't (normally) use a JCB digger to pat your dog

          (*) With appropriate size stepper motors or gearing, you don't sacrifice speed

          It seems the robot arm is from the "Sledgehammer to crack a peanut" school of problem solving, when tongs might be better suited

    They probably let this story through so that they could finger someone else as being behind the issue. Somewhere down the line they will reveal the fingerprints of a US or European hacker or even will a Ukrainian hacker as having pushed the button that harmed the child. As always the evidence that points the finger outside the country will be one that cast the rest of the world in a poor light while showing that the local security forces have their finger on the pulse and are working bravely to protect their citizens from harm.

    story made it to Russian readers and then out of the country

    And it seems to have widely made it onto all sorts of news sources. I can understand why tech news sites publish it : it is on the face of it a story of badly implemented tech, and appealing in a sort of "shucks, the poor kid had to go to the doctor because of the bad robot, but he's really OK" sort of way.

    Let's just remember that many many kids are being shot and blown to smithereens by that country, which is much less cute, and probably a good reason to be wary of stuff that sounds a lot like propaganda for the purposes of distraction from that fact.

      War is never good and should always be avoided with diplomacy if possible. A lot of people have been blown up by many countries. But why point the finger specifically at Russia, which compared to some other countires >cough<US>cough< is relatively benign if one compares body counts.

      Regarding russians not getting real news; wasn't Ukraine kicking Russia's ass? Then why are they not only still in Ukraine, they are moving west every day.

      Wishful thinking is not news.

      In other breaking news, Putin has ordered the Russian government to redefine great success to mean at least one plannned outcome in 15 years. In a rousing display of patriotism and forward-thinking, the Duma voted unanimously to approve this glorious new interpretation.

      All Russian citizens, busisness, academic institutions, government departments, and the country's armed forces, will immediately apply definition this to all ongoing endeavours, and retrospectively to past failures, proving to the world once and for all how greatly successful Russia is at anything and everything.

    This brought to mind a video that was doing the rounds of robotics labs in the mid 90s (I happened to be adjacent to one at the time).

    Some researchers were demoing their latest elegant software upgrade for their experimental robot (large, solid, clunky) for the company execs. It was supposed to retrieve a bottle of beer from the fridge. It had done the job perfectly in trials of course, but with the extra attention it decided, for reasons never made clear, to go route one. With calm deliberation, it punched its arm straight through the fridge door, grabbed a beer bottle, retrieved it, and to the consternation of the assembled onlookers, swung round, pulling the fridge door off its hinges in the process.
