Intro
AlphaBot 2 adopts a humanoid upper body mounted on a six-wheeled mobile base, with an adjustable waist-leg lifting and tilting mechanism that provides a continuous operational height range from ground level to 2,400 mm. This variable-height architecture allows the robot to work at floor level and reach above standard shelving and workbench heights within the same deployment, without requiring repositioning of the robot or manual reconfiguration. The arms have a span of 700 mm and extend to a maximum reach of 2,400 mm when the waist is at full elevation. The robot's 34 degrees of freedom span both the upper humanoid body and the waist mechanism, enabling a wide range of natural arm and body configurations for manipulation tasks across desktop-scale and factory-floor-scale environments. A fine force feedback system is integrated throughout the arm and hand joints, enabling what AI² Robotics describes as "rigid yet compliant" manipulation — the ability to apply controlled force for stable grasping while maintaining the compliance necessary to handle fragile components or interact safely with people.
The robot's AI platform, AlphaBrain, implements the GOVLA (Global and Omni-body Vision-Language-Action) model, which AI² Robotics describes as the world's first full-domain whole-body VLA architecture. GOVLA provides full-space environmental understanding, whole-body joint coordination, and complex multi-step task reasoning from a single unified model, enabling AlphaBot 2 to execute diverse tasks including cooking, sterile filling, quality inspection, and assembly without task-specific reprogramming. The open-source version of GOVLA, released as FiS-VLA in June 2025, outperformed the international benchmark model pi-zero by 30% in authoritative evaluations. AlphaBrain operates on a dual "Fast and Slow" processing architecture: a fast real-time motion planner handles immediate physical responses, while a slower deep reasoning engine manages complex task decomposition, semantic understanding, and conversational reasoning. Specific compute chip models, battery capacity, battery runtime, weight, and operating temperature are not publicly disclosed by AI² Robotics.
