Robbyant, an embodied AI company within Ant Group, has announced the upgrade and open-source release of LingBot-VLA 2.0, a next-generation vision-language-action model for robotics pre-trained on 60,000 hours of real-world physical data from 20 robot morphologies. The model demonstrates superior cross-morphology generalization, outperforming π0.5 and GR00T N1.7 on dual-arm manipulation benchmarks and achieving 3x inference efficiency improvement with latency under 150ms. Robbyant is currently conducting commercial pilots with hardware partners Leju and Ti5Robot, as well as enterprise customers GuoDa Drugstore and Longsheng Technology in retail, logistics, and industrial environments.
