Unitree Robotics, a recognized leader in advanced robotics innovation, presents the H2 EDU Smart L — a full-size, 182 cm humanoid robot that represents the absolute pinnacle of dexterous manipulation and sensory capability in the H2 EDU Smart series. This model, part of the H2 EDU Smart line, is engineered for the most demanding research in embodied AI, advanced manipulation, and human-robot interaction.

Building on the foundation of the H2 EDU Standard, the Smart L variant is equipped with two BrainCo Revo 3 U21VT Dexterous Hands featuring groundbreaking visuo-tactile sensing technology. Each hand features an impressive 21 active degrees of freedom (4 fingers × 4 DOF + thumb × 5 DOF), providing exceptional dexterity and articulation for complex manipulation tasks. The hands deliver a fingertip pinch force of 20N and a full palm grip force of 70N, with a maximum opening/closing speed of 3 Hz and a control frequency of 500 Hz. The advanced visuo-tactile system provides full palm tactile resolution of 0.01N and a minimum measurable deformation of just 130 µm, enabling unprecedented sensitivity for delicate object handling, texture recognition, and micro-manipulation research. Each hand also includes a wrist-mounted RGB camera for enhanced visual perception during fine manipulation tasks.

The H2 EDU Smart L features a total of 73 degrees of freedom (6 per leg, 7 per arm, 3 at the waist, 2 at the head, and 21 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 L 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 L 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 L 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.
