Härkingen is well-known for being at the crossroads of important highways, FWIW. It is definitely a very relevant location for logistics.

That's correct. If you're curious about the architecture: the vision part detects a chessboard, then corrects the perspective and restricts the image to just the square of the board, then looks at each square and has some simple thresholds to decide if it's occupied by a piece, and of what color. From there, the camera is treated as a black box sensor that continuously streams two 64-bit masks, for where it thinks it sees white and black pieces. There is a second program (controller) that turns that stream into a stream of chess positions (and a Unix pipe in between). The sensor is faulty of course and the controller has logic for ignoring bits from the mask where there cannot possibly be pieces etc.
