Online reinforcement learning (RL) enables robots to continuously improve through real-world interaction, yet achieving high success rates in contact-rich manipulation remains challenging due to sparse binary rewards. Conventional reward-shaping methods rely on hand-designed goal-proximity heuristics and seldom differe...

This work proposes a hierarchical closed-loop agentic LLM-based framework to ensure robust multi-robot manipulation and achieves superior success rates, ensures robust adaptability ranging from single to cross workspace manipulation, and offers a generalizable approach for diverse manipulation tasks.

LingBot-VA 2.0 is presented, a video-action foundation model built from the ground up for embodiment, which introduces a semantic visual-action tokenizer, which aligns visual representations with both semantics and actions, improving instruction following and action precision in subsequent policy learning.
