Siasun Songxing

Songxing is a bipedal humanoid from SIASUN Robot & Automation, a Shenyang company listed in Shenzhen since 2009. It was first shown at the 2025 World Robot Conference in Beijing, where coverage described a bionic structure built on self-developed core components and whole-body coordination using reinforcement and imitation learning.

At the 2026 World Robot Conference, a newer Songxing configuration was reported at 176 cm tall with 42 degrees of freedom. The same account describes a 100-TOPS multi-master real-time control system, laser-SLAM 3D mapping, multimodal vision, hand-eye coordination and voice interaction. SIASUN's 2026 half-year report says its biped uses high-thrust linear joints, brain-and-cerebellum coordinated control, reinforcement learning and imitation learning.

Earlier third-party catalog figures of 165 cm, 85 kg, 38 degrees of freedom, 12 kg payload, 3 km/h and three hours appear to describe an older or unverified configuration. Because the 2026 sources supersede the catalog on height and degrees of freedom and do not confirm the other figures, weight, payload, speed and runtime are left unknown.
