Robust Vision-Language-Action Models for Robotics
Overcoming generalization challenges in robotic manipulation through object-centric learning and seamless trajectory alignment.
Current Vision-Language-Action (VLA) models for robotics struggle with generalization due to reliance on vast, expensive datasets and overfitting to irrelevant visual cues. This paper proposes a novel object-centric learning framework and a distance-based chunk alignment mechanism to address these limitations. The framework trains VLA policies using a triplet of visual inputs (full-scene, masked target object, object-only crop) for each sub-task, ensuring actions are causally grounded in the manipulated object. Object appearance diversity is further enhanced through web-scale augmentation. During inference, a distance-based alignment at action chunk boundaries ensures smoother control transitions. Experiments in both simulation and real hardware demonstrate significant improvements in task success rates (up to 85%) and trajectory stability across various manipulation tasks, including complex cabinet opening, validating the framework's robustness and efficiency for object-aware robotic behaviors.

Advancing Robotic Interpretation and Control
Vision-Language-Action (VLA) models are pivotal for enabling robots to interpret natural-language goals and execute complex manipulation tasks. Early models, despite leveraging large datasets, often struggled with generalization beyond training distributions, over-relying on background visual cues.
Key Finding: "Existing VLA models demonstrate strong capability in unifying perception, language, and control, but they remain limited by insufficient object-level grounding. Most architectures operate on full-scene observations, causing the policy to allocate capacity to background cues that are not causally linked to task completion." This highlights the need for focused learning on task-relevant objects.
Focusing Robot Perception on What Matters
Object-centric learning (OCL) aims to factor a scene into disentangled entities, improving compositional generalization and data efficiency. In robotics, OCL principles help direct attention to specific objects involved in manipulation, rather than the entire scene.
Key Finding: "Unlike prior object-centric or region-centric approaches that focus solely on perception, our method directly injects object-level supervision into VLA training and enforces that action labels be grounded on the manipulated entity." This direct supervision prevents wasted model capacity on irrelevant background details, leading to more robust object-affordance associations.
Enhancing Long-Horizon Task Execution Stability
Action chunking improves the efficiency and stability of long-horizon manipulation by predicting short action sequences rather than single-step controls. While beneficial, this approach often introduces discontinuities at chunk boundaries, leading to potential pose drift and unstable execution.
Key Finding: "Our method focuses specifically on the boundary consistency problem: We keep the generative structure of chunking, but introduce a lightweight distance-based alignment step so that each subsequent chunk is numerically matched to the preceding end-effector pose." This ensures smooth transitions, crucial for complex, multi-step tasks.
Strategic Data Generation and Augmentation
To train object-centric VLA models effectively, demonstration videos are decomposed into object-anchored sub-tasks. For each sub-task, policies are trained with three visual views: the full scene, a masked image emphasizing the target object, and an object-only crop. Furthermore, object appearances are augmented by integrating web-crawled images with synthetic compositions.
Key Finding: "This simple yet effective formulation makes the policy repeatedly experience that action supervision originates from the manipulated object rather than from background appearance, helping improve robustness under variations in context, viewpoint, and scene configuration." This significantly boosts generalization without costly real-world data collection.
Ensuring Seamless Robot Trajectory Execution
During inference, directly concatenating action chunks can create jarring discontinuities. The proposed distance-based alignment mechanism addresses this by measuring the Cartesian distance between the terminal end-effector pose of one chunk and the initial poses of the next, then shifting the next chunk for continuity.
Key Finding: "This post-alignment step complements our representation-level grounding by reducing drift during rollout, resulting in smoother behavior without modifying the underlying policy architecture, with comprehensive validation in both simulation and real hardware demonstrating stronger generalization and smoother execution." This light-weight step significantly improves the fluidity and reliability of robotic actions.
