๐ŸŒŸ Core Highlights

Teaser

Unlike reactive VLA policies or existing WAMs that suffer from structural mismatches, ABot-M0.5 is built on the insight that mobile manipulation requires strict alignment at three levels. Our core innovations include:

  • ๐ŸŽฏ Three-Level Alignment Paradigm: We systematically identify and solve the structural bottlenecks in mobile manipulation: temporal granularity mismatch, action space entanglement, and train-test inconsistency.
  • ๐ŸŽฌ Temporal Granularity Alignment (Latent Actions): We introduce frame-level latent actions as a bridging space between coarse video latents and fine-grained robot controls, effectively capturing local visual state transitions and contact dynamics.
  • ๐Ÿค– Action Space Alignment (Dual-level MoT): We design an Action-Decoupled Mixture-of-Transformers architecture that separates heterogeneous action subspaces (e.g., base movement and arm manipulation), preventing action-distribution conflicts.
  • ๐Ÿง  Inference Consistency Alignment (Dream-Forcing): We propose a novel training strategy that progressively trains inverse dynamics on model-predicted (dreamed) videos, perfectly aligning training conditions with autoregressive inference and eliminating error accumulation.
  • ๐Ÿ† State-of-the-Art Performance: ABot-M0.5 achieves SOTA results across challenging benchmarks (RoboCasa365, RoboTwin 2.0, LIBERO-Plus) and demonstrates robust zero-shot generalization in real-world long-horizon mobile manipulation tasks.
