A Pragmatic VLA Foundation Model

<p align="center"> <img src="assets/Teaser.png" width="100%"> </p>

LingBot-VLA has focused on Pragmatic:

• Large-scale Pre-training Data: 20,000 hours of real-world data from 9 popular dual-arm robot configurations.
• Strong Performance: Achieve clear superiority over competitors on simulation and real-world benchmarks.
• Training Efficiency: Represent a 1.5 ∼ 2.8× (depending on the relied VLM base model) speedup over existing VLA-oriented codebases.
