When I read about this my first question was why they use industrial machine as a chess robot. I believe that the answer is “just to show off”. But IMO this makes an opposite effect. They could use a pair of magnets attached to each chess piece and chess board. One under the board, one attached to the piece. Then move magnets under the board and voila chess pieces move automagically. I think that I saw a similar toy somewhere.
