NimbRo-OP2X: Adult-sized Open-source 3D Printed Humanoid Robot
  Humanoid robotics research depends on capable robot platforms, but recently
developed advanced platforms are often not available to other research groups,
expensive, dangerous to operate, or closed-source. The lack of available
platforms forces researchers to work with smaller robots, which have less
strict dynamic constraints or with simulations, which lack many real-world
effects. We developed NimbRo-OP2X to address this need. At a height of 135 cm
our robot is large enough to interact in a human environment. Its low weight of
only 19 kg makes the operation of the robot safe and easy, as no special
operational equipment is necessary. Our robot is equipped with a fast onboard
computer and a GPU to accelerate parallel computations. We extend our already
open-source software by a deep-learning based vision system and gait parameter
optimisation. The NimbRo-OP2X was evaluated during RoboCup 2018 in Montréal,
Canada, where it won all possible awards in the Humanoid AdultSize class.
