Robbyant Releases LingBot-VLA 2.0: An Open-Source 6B Vision-Language-Action (VLA) Model for Cross-Embodiment Robot Manipulation
Robbyant released LingBot-VLA 2.0, an open-source 6-billion-parameter vision-language-action model for robot manipulation across different hardware setups.
- LingBot-VLA 2.0 is an open-source 6B parameter vision-language-action model for robot manipulation.
- Pretrained on 60,000 hours of data, including 50,000 hours of robot trajectories across 20 configurations.
- Uses a token-level Mixture-of-Experts architecture without load-balancing loss for scalability.
- Maps all robot embodiments into a shared 55-dimensional action space for cross-embodiment manipulation.
Robbyant, an Ant Group subsidiary focused on robotics, has launched LingBot-VLA 2.0, an open-source vision-language-action (VLA) model designed to unify robot manipulation across diverse hardware configurations. The 6-billion-parameter model is pretrained on approximately 60,000 hours of data, including 50,000 hours of robot trajectories spanning 20 different robot setups and 10,000 hours of egocentric human video footage.
A key innovation in LingBot-VLA 2.0 is its token-level Mixture-of-Experts architecture, which scales model capacity without requiring a load-balancing loss. The model maps all robot embodiments into a shared 55-dimensional canonical action space, covering a wide range of robotic components such as arms, dexterous hands, waists, heads, and mobile bases. This approach aims to enable seamless cross-embodiment manipulation, allowing robots with different physical configurations to perform tasks using a unified policy.
The release is Apache-2.0 licensed, making it freely available for research and commercial use. Robbyant positions this model as a step toward more generalizable and adaptable robotics systems, potentially reducing the need for task-specific fine-tuning across different robotic platforms.
