I call buggy software. Somebody should have checked (no pun intended) that the bot could recognize the difference between a child’s finger and a playing piece, yet we march inexorably toward self-driving cars. What could go wrong?
So, whose move was it? Apparently someone’s hand was on the board that shouldn’t have been-- Whose was it?
And even if the robot thought that the kid’s finger was a piece, shouldn’t that have looked like an invalid board, because it knew what the prior position was and a finite list of possible moves the kid could have made?
Decades ago, there was a chess computer that moved the pieces safely.
The computer was contained in a sealed plastic box with a chess board on the top.
Each piece had a magnet in its base and inside the box was a set of levers with another magnet to drag pieces into position. The computer moved the levers, avoiding knocking over any pieces still on the board.
