  Over the past few years, the Humanoid League rules have changed towards more
realistic and challenging game environments, which encourage teams to advance
their robot soccer performances. In this paper, we present the software and
hardware designs that led our team NimbRo to win the competitions in the
AdultSize league -- including the soccer tournament, the drop-in games, and the
technical challenges at RoboCup 2018 in Montreal. Altogether, this resulted in
NimbRo winning the Best Humanoid Award. In particular, we describe our
deep-learning approaches for visual perception and our new fully 3D printed
robot NimbRo-OP2X.
