The X-Humanoid Tien Kung 3.0 is an embodied humanoid robot platform designed as a general-purpose robot mother platform for research. It features full-stack self-developed intelligent integrated joints with high torque density, large hollow design, extreme lightweight construction, and full-series precision gears. Capabilities include low-latency voice interaction with generalized Q&A and active human-like guidance for unmanned tours, autonomous door opening and complex instrument reading with abnormal behavior recognition for security patrol in hazardous environments, and real-time visual recognition with dual-arm collaboration for autonomous bin picking, parts sorting, and dynamic path planning in industrial logistics. It is part of the Tien Kung open-source initiative. Targets generalist and research applications.
