Unitree Robotics — H2 Plus Ultimate Series Unitree H2 Plus Ultimate-A Full-size 182 cm humanoid robot with dual Dex1-1 Advanced Grippers, 33 total DOF, adjustable 5–120 N gripping force, 20 kg form-fitting payload, 0.24-second closure time, NVIDIA Jetson Thor AI compute and wrist RGB cameras. 33 Total DOF 120 N Max Grip Force 20 kg Form-Fitting Payload 0.24 s Closure Time 2070 TFLOPS AI The Pinnacle of the H2 Plus Series Unitree Robotics, a recognized leader in advanced robotics innovation, presents the H2 Plus Ultimate-A — a full-size, 182 cm humanoid robot that represents the pinnacle of the H2 Plus series, combining the ultimate AI compute capability with advanced dexterous manipulation. This model is engineered for the most demanding research in embodied AI, dexterous manipulation, and human-robot interaction. Dual Dex1-1 Advanced Grippers Building on the powerful H2 Plus Smart platform, the Ultimate-A variant is equipped with two Dex1-1 Advanced Grippers, each featuring a wrist-mounted RGB camera. These high-performance grippers deliver adjustable gripping force from 5 to 120 N, a form-fitting payload of 20 kg, and a minimum full-stroke closing time of just 0.24 seconds. With a fingertip position resolution of 0.1 mm, a 90 mm stroke, 80 mm finger length, and high-speed 485 communication, the grippers support precise and delicate manipulation tasks essential for advanced robotics research. Fast, Powerful and Precise Gripping Each gripper weighs 550 g and measures 143 × 78 × 67 mm. It supports a form-fitting payload of 20 kg and a friction-based payload of 5 kg, combining high holding force with fast response and fine positional control. Wrist-Mounted RGB Cameras Each gripper includes a wrist-mounted RGB camera with a 130° diagonal field of view and 1920 × 1080 resolution, delivering high-quality visual feedback for close-up perception during fine manipulation tasks. 33 Degrees of Freedom The H2 Plus Ultimate-A features 33 total degrees of freedom: 6 per leg, 7 per arm, 3 at the waist, 2 at the head, and 1 per gripper. This configuration provides exceptional range of motion while adding fast and precise end-effector control. NVIDIA Jetson Thor AI Compute At its core, the H2 Plus Ultimate-A is powered by the NVIDIA Jetson Thor module, delivering 2070 TFLOPS of AI performance in FP4 sparse mode through its 2560-core NVIDIA Blackwell architecture GPU with 5th Generation Tensor Cores. The 14-core Arm® Neoverse®-V3AE 64-bit CPU runs at 2.6 GHz and is combined with 128 GB of LPDDR5X memory at 273 GB/s. The system also includes an Intel Core i5 processor for platform functionality and an Intel Core i7 processor for user development, with an empty PC4 slot for optional upgrades. High-Torque Whole-Body Actuation Constructed from aerospace-grade aluminum, titanium alloy, and high-strength engineering plastics, the H2 Plus Ultimate-A weighs approximately 70 kg with battery. Its joint motors deliver up to 360 N·m in the legs and 120 N·m in the arms, enabling dynamic and precise whole-body movements. Perception, Interaction and Connectivity The robot features a bionic head and face, wide-field-of-view humanoid stereo cameras with a 140° horizontal and 102° vertical field of view, array microphones, and high-power speakers. Wi-Fi 6 and Bluetooth 5.2 support seamless integration into modern research environments. Full Secondary Development The H2 Plus Ultimate-A supports full secondary development through open APIs, deep system access, and SDK support for ROS2, Python, and C++.
