Product overview
About Bonn NimbRo-OP2
NimbRo-OP2 is an AdultSize humanoid from the University of Bonn's Autonomous Intelligent Systems group, led by Prof. Sven Behnke. The group lists it at about 135 cm tall and 18 kg, with 18 joints: five per leg, three per arm and two in the neck. A 2018 paper gives a higher count of 34 Dynamixel actuators, because the legs use parallel linkages.
Bonn's 2017 press release reports that the robot won the RoboCup 2017 AdultSize football tournament in Nagoya, and that it received the RoboCup Design Award, sponsored by Flower Robotics. The 2018 paper, 'NimbRo-OP2: Grown-up 3D Printed Open Humanoid Platform for Research', presents the platform as fully open-source in hardware and software. It uses a 720p wide-angle camera, an Intel NUC computer and a 4-cell LiPo battery, which the paper says gives 15 to 30 minutes of runtime.
The group's team page also lists NimbRo-OP2X, a 2018 variant, and publishes CAD files for the robot on GitHub. No sales page or price was found. The entry is marked discontinued because the platform has been superseded by NimbRo-OP2X; the maker has not issued a discontinuation notice.
