HiVLA: A Visual-Grounded-Centric Hierarchical Embodied Manipulation System
HiVLA introduces a hierarchical, visual-grounded-centric framework explicitly decoupling high-level semantic planning from low-level motor control in robotic manipulation. This resolves the fundamental trade-off where fine-tuning end-to-end VLA models on narrow control data compromises the deep reasoning capabilities inherited from base Vision-Language Models (VLMs).
The system employs a VLM planner for task decomposition and visual grounding, generating structured plans with precise target bounding boxes. A novel flow-matching Diffusion Transformer (DiT) action expert, equipped with a cascaded cross-attention mechanism, translates these plans into robust physical actions. This design allows HiVLA to significantly outperform state-of-the-art end-to-end baselines, particularly excelling in long-horizon skill composition and fine-grained manipulation of small objects in cluttered scenes, while preserving VLM's zero-shot reasoning and enabling independent component improvements.

Hierarchical Design for Robust Manipulation
HiVLA addresses the fundamental trade-off in VLA models by explicitly decoupling high-level semantic planning from low-level motor control. It leverages a VLM planner for task decomposition and visual grounding, generating structured plans with subtask instructions and precise bounding boxes. A DiT action expert then translates these plans into physical actions using a novel cascaded cross-attention mechanism for robust execution. This preserves VLM's reasoning while allowing independent component improvements.
Intelligent High-Level Planning
The High-Level VLM Planner Agent acts as the system's 'brain,' interpreting high-level instructions and visual scenes to decide the next logical step. It generates structured JSON plans including a subtask description, action type, target object name, and a normalized bounding box. This decoupling allows the VLM to retain its sophisticated reasoning capabilities without fine-tuning on low-level manipulation data, avoiding catastrophic forgetting.
Precise Low-Level Motor Control
The low-level action expert is a Conditional Diffusion Transformer (DiT) designed for precise motor control. Its key innovation is a cascaded cross-attention mechanism that sequentially integrates global visual context, high-resolution object-centric features (augmented with absolute positional encodings), and subtask language embeddings. This ensures the expert fully leverages the VLM's cognitive output to understand what, where, and how to act, leading to fine-grained manipulation.
Leading Performance in Complex Tasks
HiVLA significantly outperforms state-of-the-art end-to-end baselines in both simulation and real-world experiments. It achieves an 83.3% total average success rate on RoboTwin, a 17.7% absolute improvement over H-RDT, and 42.7% over π0. The system excels in long-horizon skill composition and fine-grained manipulation of small objects in cluttered scenes, demonstrating robustness to planner errors and maintaining an 8Hz control frequency.

Real-World Dexterity in Cluttered Environments
HiVLA's hierarchical, visual-grounded design proves highly effective in real-world scenarios, particularly in complex, cluttered multi-object tasks where baselines struggle. Unlike H-RDT, which relies solely on global features and fails in scenarios like '3 Cups' or '3 Blocks,' HiVLA's precise local visual-language conditions enable it to accurately disambiguate identical shapes and execute fine-grained sub-skills. This allows HiVLA to navigate demanding physical tasks with remarkable accuracy and robust generalization.
