LingBot-VLA 2.0: one VLA policy, 20 robot bodies, ~60k hours real-robot and human video
Robbyant released LingBot-VLA 2.0, a single model driving 20 embodiments from single-arm Franka and dual-arm UR7e up to full humanoids like Unitree G1 and Fourier GR-2. The action space also covers head, waist, mobile base, and dexterous hands, not only dual-arm manipulation. Training data is roughly 50,000 hours of real-robot trajectories across those 20 configs plus 10,000 hours of egocentric human video, filtered and reconstructed. The ablations on 4 GM-100 real-robot tasks show a clean result: relative joint actions over absolute lifted average success from 33.7% to 55.0%, with relative joint positions cutting the action standard deviation to roughly a third of absolute (about 0.28 vs 0.80). On its own GM-100 generalist eval, Robbyant self-reports higher progress and success than pi-0.5 and GR00T N1.7. Absolute success remains low: 34.4% on Agilex and 15.6% on Galaxea, with several tasks at 0%. The paper itself notes the model often makes partial progress then fails at the final precise placement or release. OOD performance degrades sharply. submitted by /u/deepmoss47 [link] [Kommentare] reddit.com · reddit.com
