Robot of the Day: April 24

It was not notable that this structure did not appear on any maps. While the maps on file were highly detailed and thoroughly annotated, there were large areas outside population centers that were completely unknown. This was one such area. What was notable was that this structure was apparently abandoned and showed signs consistent with a lengthy period of vacancy without any maintenance. That such a structure would go unused (and unmaintained!) for so long seemed irrational.
