Hydrotec was a Swiss robot that competed in German Robot Wars. Hydrotec was built by Paul Koch, who would later build Snake Bite, which would make two appearances in international competitions in the UK Series. For unknown reasons, Koch was unable to attend filming for German Robot Wars. Despite this, Hydrotec did relatively well in its only competition, defeating Delldog in Round 1 but losing to the eventual champion, Black Hole, in the Heat Final. Hydrotec was scheduled to take part in the Losers Melee to determine fifth through eighth place, but withdrew, presumably due to damage sustained from Black Hole.
