Robot is a series of books containing the art of various Asian artists, created by Range Murata. Volume 1 was released on October 21, 2004, and ten volumes have currently been released. Digital Manga Publishing was originally responsible for the North American distribution, with the first volume being released August 6, 2005. However, due to talks over publishing negotiations breaking down, DMP stopped publishing Robot after Volume 3. Rights were picked up by UDON Entertainment who began distribution on December 24, 2007 with Volume 4, with the plan of releasing all subsequent releases on a quarterly basis, but has since halted after the fifth volume.
