> I wonder if another mechanism altogether could work a bit better -- a matrix of electromagnets embedded under the board, with a resolution of say 1/4", so that when deployed in sequence, they could move the pieces from one magnetic field to another and another, without any actual moving parts involved. A standard chessboard has squares of 2-2.5”, so this would require at least 4096 electromagnets. There was a kickstarter [1] for such a design a couple years ago. The conclusion in the chess community was that the kickstarter was a fraud [2] (with faked videos) and such a board would not be commercially feasible.
