A research team led by Ronghan Chen (21 authors total) submitted ABot-M0.5, a new World Action Model designed for general-purpose mobile manipulation robots, to arXiv on July 1, 2026.
The model addresses critical limitations in existing VLA policies and WAM approaches, including lack of explicit world modeling, coarse video processing, entangled navigation-manipulation actions, and error accumulation in long-horizon tasks.
ABot-M0.5 aligns mobile manipulation across three structural levels—temporal granularity, action space, and train-test consistency—and introduces intermediate latent actions to capture fine-grained contact dynamics and improve inference accuracy.
