LingBot‑VLA 2.0 Boosts Cross‑Bot Manipulation – Open Source

Many robotics teams struggle to move vision-language-action models from the lab to real-world robots. The models often overfit to a single arm or a narrow set of tasks, fail when the robot’s joints or gripper change, and cannot predict the future effects of their actions, leading to jerky or unsafe motion. Collecting and cleaning enough varied data is time-consuming, and most open-source checkpoints require heavy compute that only a few labs can afford. Integrating a new policy into existing ROS-based stacks usually means rewriting the action interface and tuning hyper-parameters for each robot embodiment.

LingBot-VLA 2.0 tackles these pain points directly. It is trained on 60,000 hours of robot trajectories and egocentric video covering twenty different hardware configurations, from single-arm manipulators to full humanoids. A unified 55-dimensional state-action vector lets the same policy control arms, hands, grippers, waists, heads and mobile bases without redesigning the output layer. The model’s Mixture-of-Experts action head keeps active computation bounded, so a single forward pass needs only about 130 ms on an RTX 4090D. Dual-query distillation adds explicit depth and semantic foresight, letting the policy anticipate future frames and produce smoother trajectories. The released Apache-2.0 codebase includes scripts to download the 6B checkpoint, compile the policy server with torch-compile, and run inference on any robot that publishes camera images and accepts the canonical 55-D action vector. Teams can fine-tune on their own LeRobot datasets using the provided Muon or AdamW optimizers, and the modular MoE routing lets them scale compute as needed.

By providing a ready-to-use, generalist policy with built-in data cleaning, unified representation and efficient inference, LingBot-VLA 2.0 reduces the engineering barrier for deploying robust, adaptive robot behaviors in production settings.
