Personal chess computers that move their own pieces have been reality for at least 40 years.
However, basic laws of physics and economics suggest that trying to build a legitimate, Regium-like device would be too expensive to be able to produce and sell, if it could even be done with available technology.
If you want to play chess there are plenty of options. For centuries you can play against other people or against yourself. You can even play in your head without a chess board if you are really into it. A few decades ago they made the first chess computers that could beat the average chessplayer without much of an effort. Moving the pieces yourself somehow reminds you that you play against a computer. At least for me, it does.
Therefore I was happy to see Square Off (founded in 2015) hitting the world of chess a few years ago. A fantastic product that is in someway a challenger for DGT Centaur. Or the other way around. Both products have fantastic capabilities and are revolutionary for this time. The 'problem' with the Square Off is that it makes noise, is a bit slow and relies on external calculations. The problem with DGT Centaur (and the other DGT products) is that you have to move the pieces yourself. They deserve a lot of credit of course for revolutionizing chess!
If you are into chess computers you may have heard of the Regium Chess Computer. It is a scam, but it shows that there is a lot of backing for such a chess concept. This is because the concept has the best of a few worlds. It has connectivity, plays moves by itself, has a built-in computer, has a built-in battery, and looks good.
My question for this community is why this concept would not be possible to make? We have small computers like the raspberry pi (also used by DTG), we have microchips, we have electromagnets,... What is withholding the chess-industry from making such an automated good-looking, automated chess-computer? I am curious about your thoughts!
