Unitree Robotics, a recognized leader in advanced robotics innovation, presents the H2 EDU Smart D — a full-size, 182 cm humanoid robot that combines the power of the H2 platform with the most advanced dexterous manipulation capabilities available. This model, part of the H2 EDU Smart series, is engineered for cutting-edge research in embodied AI, dexterous manipulation, and human-robot interaction.

Building on the foundation of the H2 EDU Standard, the Smart D variant is equipped with two Dex5-1 Dexterous Hands (non-tactile version). Each hand features an impressive 16 active degrees of freedom (thumb: 4 DOF, index/middle/ring/little: 3 DOF each), powered by 12 self-developed micro force-controlled compound joints and 4 micro force-controlled gear joints. This advanced actuation system enables proprioception without the need for tactile sensors, delivering exceptional precision and dexterity for complex manipulation tasks. Each hand also includes a wrist-mounted RGB camera for enhanced visual perception during fine manipulation tasks.

The H2 EDU Smart D features a total of 63 degrees of freedom (6 per leg, 7 per arm, 3 at the waist, 2 at the head, and 16 per dexterous hand), providing the highest level of dexterity and range of motion in the H2 EDU series. Each hand includes a wrist RGB camera with a 130° field of view and 1920 x 1080 resolution, delivering high-quality visual feedback for close-up perception during fine manipulation tasks.

At its core, the H2 EDU Smart D is equipped with both an Intel Core i5 processor for platform functionality and an Intel Core i7 processor for user development. The robot also features empty slots for PC3 and PC4 high-performance computing modules (up to 2 units, similar to B2 slot format), supporting optional upgrades such as NVIDIA Jetson Thor or Intel Core i7 + NVIDIA Jetson Orin NX for demanding AI workloads.

Constructed from aerospace-grade aluminum, titanium alloy, and high-strength engineering plastics, the H2 EDU Smart D is both durable and lightweight. Its powerful joint motors deliver up to 360 N·m of torque in the legs and 120 N·m in the arms, enabling dynamic and precise whole-body movements. Industrial-grade cross-roller bearings at the joints ensure high precision and load capacity.

The robot features a bionic head and face, wide-field-of-view binocular cameras, and a voice interaction system with array microphones and high-power speakers for natural human-robot communication. With Wi-Fi 6 and Bluetooth 5.2 connectivity, the H2 EDU Smart D integrates seamlessly into modern research environments. A handheld remote controller, quick-swap smart battery, and charger are included for immediate deployment.

The default configuration includes a protective bracket for added safety during development and testing.
