Qinglong V3.0

Qinglong V3.0, developed by OpenLoong (Humanoid Robots Shanghai Co., Ltd.), represents a significant advancement in open-source full-size humanoid robotics, launched in August 2025 as an evolved research platform for embodied AI, locomotion, manipulation, and whole-body control. Building on the foundational Loong platform, it emphasizes practicality for real-world scenarios including industrial tasks, public service, disaster response, and domestic applications. The robot's architecture is highly modular and biomimetic, featuring bionic joint configurations that mimic human kinematics for enhanced mobility and dexterity. Key structural modules include the head perception system (integrating vision, audition, and tactile sensing), chest computing unit, waist for torso dynamics, upper limbs with 7 DoF per arm, lower limbs with advanced leg-foot assemblies for terrain adaptation, and dexterous hands with 12-19 DoF total. The control system employs a multi-level hierarchical architecture separating proprioceptive stabilization (fast loop at 2 kHz via EtherCAT bus) from perceptual decision-making (slower loop). Dual EtherCAT masters manage upper and lower body slaves, ensuring low-latency (150-250 ms end-to-end) responses. Computing power reaches 400 TOPS via dual 2.2 GHz CPUs and dual 930 MHz GPU coprocessors, supporting real-time sensor fusion, AI inference, and motion planning on a Linux/ROS OS. AI integration leverages the 'Gewu Zhizhi' embodied intelligence system for multimodal perception and autonomous operation, with open-source support for LLM integration and reinforcement learning via GymLoong simulator. Sensors include 3D LiDAR, RGB-D cameras (~1080p), microphone arrays, fingertip/palm tactile arrays, torque/position encoders in joints, and IMUs for balance. Actuators use high-torque electric servos with harmonic drives (upper body) and planetary gears/QDD (lower body), enabling peak torques up to 396 Nm, walking speeds of 4.5-5 km/h, 20 kg payload, and terrain handling (20° slopes, 13-15 cm steps, unstructured surfaces like gravel/sand). Deployment history remains primarily in research and demo phases. Debuted at WAIC 2024 (base model), V3.0 showcased skills like precise manipulation, agile navigation, and multimodal grasping in 2025 events. OpenLoong's GitHub repositories (Hardware, Dyn-Control, GymLoong) foster community development, with early production units in academic labs for R&D. No widespread commercial deployments yet, but open-source ethos accelerates benchmarking and customization, positioning Qinglong V3.0 as a benchmark for China's humanoid ecosystem toward practical autonomy.
