WUBA D12

BESCHREIBUNG

The D12 is WUBA's full-size humanoid — 175 cm and 65 kg with its battery — and the specification that shapes it is the joint: high-performance integrated joints rated to 300 N·m, which the company frames as a safety and stability figure rather than a raw power claim, since a humanoid that cannot hold a posture under load is a hazard. Articulation is generous: seven degrees of freedom per arm so the hand can reach any point in the working volume at a chosen wrist angle, six per leg for walking, running and stairs, and twelve per hand across a five-fingered design that supports several grasp modes and fine manipulation. Its feet are force-controlled with multiple degrees of freedom, letting it adapt to uneven ground rather than merely tolerate it. Perception combines a hybrid solid-state 3D LiDAR giving 360-degree stereo coverage with dual depth stereo cameras for multi-layer distributed perception, fused for navigation and obstacle avoidance. A high-resolution curved LCD serves as its face for expressive interaction. It walks at 3.6 km/h, tops out at 6.5 km/h, carries 20 kg, works within a 750 mm radius and runs two hours, with EtherCAT, WiFi and 5G links and support for secondary development.
