Being-H0.5: Scaling Human-Centric Robot Learning for Cross-Embodiment Generalization
Abstract: We introduce Being-H0.5, a foundational Vision-Language-Action (VLA) model designed for robust cross-embodiment generalization across diverse robotic platforms. While existing VLAs often struggle with morphological heterogeneity and data scarcity, we propose a human-centric learning paradigm that treats human interaction traces as a universal "mother tongue" for physical interaction. To support this, we present UniHand-2.0, the largest embodied pre-training recipe to date, comprising over 35,000 hours of multimodal data across 30 distinct robotic embodiments. Our approach introduces a Unified Action Space that maps heterogeneous robot controls into semantically aligned slots, enabling low-resource robots to bootstrap skills from human data and high-resource platforms. Built upon this human-centric foundation, we design a unified sequential modeling and multi-task pre-training paradigm to bridge human demonstrations and robotic execution. Architecturally, Being-H0.5 utilizes a Mixture-of-Transformers design featuring a novel Mixture-of-Flow (MoF) framework to decouple shared motor primitives from specialized embodiment-specific experts. Finally, to make cross-embodiment policies stable in the real world, we introduce Manifold-Preserving Gating for robustness under sensory shift and Universal Async Chunking to universalize chunked control across embodiments with different latency and control profiles. We empirically demonstrate that Being-H0.5 achieves state-of-the-art results on simulated benchmarks, such as LIBERO (98.9%) and RoboCasa (53.9%), while also exhibiting strong cross-embodiment capabilities on five robotic platforms.

Being-H0.5: Scaling Human-Centric Robot Learning for Cross-Embodiment Generalization
Motivation and Paradigm Shift
Being-H0.5 is introduced as a foundational Vision-Language-Action (VLA) model engineered for robust cross-embodiment generalization, addressing the morphological heterogeneity and data scarcity that limit existing VLAs. The central thesis is human-centric learning: treating human interaction traces as universal priors for physical manipulation and using them to bootstrap robotic intelligence across diverse hardware platforms. To operationalize this, UniHand-2.0—a large-scale multimodal corpus exceeding 35,000 hours across 30 robot embodiments and comprising 400M samples—is curated as a pre-training resource.
Figure 1: Overview of UniHand 2.0, integrating large-scale human demonstrations, robot manipulations, and vision-text data for generalizable human-centric robot learning.
UniHand-2.0: Data Scale and Embodiment Diversity
UniHand-2.0 represents a substantial leap in dataset size and diversity in the embodied AI landscape. It features:
- 16,000 hours of egocentric human video for foundational manipulation priors.
- 14,000 hours of robot manipulation demonstrations spanning 30 robot types (single/dual arm, grippers, dexterous hands, legged robots).
- 5,000 hours of vision-language understanding data to maintain reasoning capability for long-horizon tasks.
This scale and morphological diversity are critical for learning action manifolds that span from simple gripper actuations to high-DoF dexterous hand manipulation, mitigating the representational drift observed when VLAs encounter new robot morphologies.
Figure 2: UniHand-2.0 provides the largest and most diverse VLA pre-training recipe, crucial for embodiment-agnostic skill transfer.
The composition maintains a balanced ratio of simulation to real-world data (26% vs. 74%), ensuring the generalizability of learned skills while restricting overfitting to simulated domains.
Figure 3: UniHand-2.0 achieves a balanced split of simulation and real-world data and comparable scale between human, robot, and VLM modalities.
UniCraftor: Modular Data Collection
To overcome deficiencies in open-source datasets (missing depth, imprecise camera extrinsics, sparse event annotation), UniCraftor is engineered as a portable, modular data collection system. It affords synchronized RGB-D, precise camera pose calibration, and hardware-triggered interaction events, improving the temporal granularity and geometric fidelity of training data for fine-grained policy learning.
Figure 4: UniCraftor enables scalable, multimodal data acquisition with synchronized cues for robust human-centric learning.
Foundation Model Architecture
Being-H0.5 employs a Mixture-of-Transformers (MoT) architecture, decomposing reasoning (multimodal understanding) and motor policy (action expert) into disentangled yet inter-coupled pathways. The backbone is initialized from the InternVL-3.5 VLM, with innovations in integrating human and robot action signals into a Unified State-Action Space, supporting serialization of heterogeneous modalities (vision, text, state, action) into a unified token stream. Continuous actions use rectified flow matching for superior action chunk generation, while discrete hybrid motion tokens, derived from quantization of human hand movement, inject behavior priors.
Figure 5: Being-H0.5 enables unified multimodal reasoning and action generation for heterogeneous embodiments via shared attention and MoF specialization.
The Mixture-of-Flow (MoF) mechanism scales action branch capacity by combining shared dynamic layers (motor primitives) with routed, specialized experts, maintaining deployment efficiency and avoiding cross-embodiment interference.
Robust Deployment: MPG and UAC
Being-H0.5 addresses deployment-time instability using:
- Manifold-Preserving Gating (MPG): This mechanism leverages Sliced-Wasserstein discrepancy metrics between observation and action embedding to dynamically gate feature-dependent residuals and fallback to prior offsets when context reliability degrades.
- Universal Async Chunking (UAC): By modeling embodiment-specific inference latency and control frequency, UAC schedules hard prefix locking and buffer stitching to minimize action discontinuities during real-time, asynchronous control across platforms.
Figure 6: MPG provides robust feature gating under distribution shift, while UAC enables consistent action execution amid heterogeneous robot latencies.
Deployment infrastructure adopts a dual-thread ring buffer for safe separation of inference and control, architecturally supporting real-time operation on disparate robots with varying frequencies and compute budgets.
Empirical Evaluation
A diverse set of five real robotic platforms is used for experimental validation, covering humanoids, dexterous and parallel gripper arms.
Figure 7: The heterogeneous set of real robots used to evaluate cross-embodiment generalization and deployment robustness of Being-H0.5.
Rollouts illustrate successful long-horizon, bimanual, spatial, and generalization tasks.
Figure 8: Example rollouts demonstrate robust execution of complex multi-step and bimanual manipulation task suites across embodiments.
Success rates across categories reveal that embodiment-specific post-training yields maximal performance but generalist joint training retains high success, even outperforming specialist policies in overlap-rich settings. Notably, zero-shot embodiment transfer emerges: single checkpoints trained jointly across embodiments achieve nontrivial success on previously unseen robot-task pairs.
Figure 9: Real-robot success rates show strong cross-embodiment performance, substantial improvements from human-centric pretraining, and clear ablation results for model components.
Ablation Studies and Adaptation Sensitivities
Freezing backbone layers demonstrates that semantic planning benefits from stability, while action experts require plasticity for fine-grained control adaptation. Hybrid motion representation with discrete masked prediction significantly improves intent alignment under noisy, in-the-wild conditions.
Figure 10: Performance as a function of frozen layers in the action expert, highlighting the trade-off between backbone transfer and expert adaptation.
Figure 11: Relative performance drop as more layers of the action expert are frozen, emphasizing the need for plastic low-level control adaptation.
Removal of MPG and UAC mechanisms results in catastrophic drops in long-horizon and bimanual tasks due to compounding errors and temporal mismatches.
Figure 12: MPG+UAC ablation reveals critical role in mitigating error accumulation for complex temporal and bimanual coordination tasks.
Simulation Benchmarks
On LIBERO and RoboCasa simulation suites, Being-H0.5 achieves leading aggregate success rates (98.9% on LIBERO, 53.9% on RoboCasa) using only low-res RGB input, outperforming several prior VLA and multimodal baselines, and demonstrating near-identical performance in generalist (joint-training) and specialist (benchmark-specific) regimes.
Implications and Future Directions
The study demonstrates that large-scale, human-centric pretraining combined with unified state-action representation endows cross-embodiment VLAs with robust skill transfer, emergent zero-shot generalization, and operational efficiency. The dual innovations in architecture (MoT/MoF) and robust deployment (MPG/UAC) address both the representational and practical bottlenecks in scaling robotic intelligence.
Practically, the methodology facilitates rapid adaptation to new hardware and tasks with limited data, while theoretically, it moves robot learning toward compositional and transferable policy development. Scaling post-training data diversity and developing further abstraction-level priors are key for advancing toward general-purpose robotic agents with compositional intelligence and resilient execution across real-world domains.
Conclusion
Being-H0.5 establishes a scalable human-centric robot learning paradigm, leveraging unified state-action representation and architectural modularity. Empirical results validate robust real-world deployment and cross-embodiment policy generalization, supported by large-scale multimodal pretraining and deployment-aware inference. The framework paves the way for future advances in general-purpose, transferable, and context-resilient robotic intelligence (2601.12993).

What is this paper about?
This paper introduces Being‑H0.5, a new kind of robot “brain” that can see, read instructions, and move (a Vision‑Language‑Action model). Its big goal is to teach one model to work across many different robot bodies—small arms, two‑armed robots, and even humanoids—without starting over for each machine. To make that possible, the team builds a huge training set called UniHand‑2.0 and a “universal grammar” for robot actions so different robots can learn from the same examples, especially from human hand movements.
What questions were the researchers trying to answer?
- How can a robot quickly learn to use a new body (new arms, hands, speeds) without tons of new data?
- Can we use human videos and hand motions as a “mother tongue” of physical interaction that robots can learn from?
- Is there a way to represent actions so different robots “speak” the same action language?
- Can one model understand what it sees and reads, and then act, all in the same system?
- How do we keep robot behavior stable and safe when sensors are noisy or when robots operate at different speeds?
How did they do it?
A massive, human‑centric dataset: UniHand‑2.0
The team built one of the largest training collections for robot learning:
- Over 35,000 hours of data (about 400 million examples), including:
- 16,000 hours of first‑person human videos showing hands interacting with objects
- 14,000 hours of robot demonstrations from 30 different robot types
- About 5,000 hours’ worth of vision‑and‑text data to keep the model good at reading and reasoning
- Think of this as teaching the robot from both “human teachers” (videos of people using their hands) and “robot classmates” (many different robots doing tasks).
A Unified Action Space (a shared “alphabet” of moves)
Different robots have different controls—some have simple grippers, others have many moving fingers. The team designed a shared action space that maps all these different controls into common “slots” with the same meaning. Imagine teaching dance moves by meaning (“grasp gently,” “rotate wrist”) instead of by specific muscle movements—then any dancer (robot) can adapt the move to their own body.
One sequence for everything
They turn every type of data—videos, words, and actions—into one stream of small pieces (tokens), like words in a sentence. The model learns to:
- Read and answer questions (text tokens)
- Understand what it sees (vision tokens)
- Predict the next helpful move (action tokens) This way, perception, understanding, and action are trained together, not as separate parts.
A “team of experts” model: Mixture‑of‑Transformers + Mixture‑of‑Flow
The architecture separates higher‑level thinking from low‑level muscle control:
- General “reasoning” parts understand images and instructions.
- Specialized “action experts” focus on different bodies or motion styles. A router chooses which expert to consult for each situation, a bit like asking the right coach for a specific sport. “Flow” here means generating smooth, continuous motion, like planning a path your hand follows instead of jumping from point to point.
Stability and timing tricks
- Manifold‑Preserving Gating: When the camera view is unclear, the model leans more on safe, reliable motion patterns—like staying on the “safe roads” of movement rather than guessing wildly.
- Universal Async Chunking: Robots act at different speeds and have different reaction delays. The model learns to produce short chunks of actions that still work well even if a robot is fast, slow, or laggy—kind of like speaking in phrases that sound natural whether someone listens in fast‑forward or slow‑motion.
A better way to collect human data: UniCraftor
They built a portable recording system to capture high‑quality human demonstrations:
- Depth cameras for 3D information
- Precise camera positioning using AprilTags (QR‑like markers) and a math method to locate the camera exactly
- A foot pedal to mark the exact moments of important events (like “touch” or “release”) This yields cleaner, more accurate training signals for learning how hands truly interact with objects.
What did they find?
- Strong generalization across robots: One Being‑H0.5 model checkpoint controlled five very different robots (including Franka arms, a humanoid Unitree G1, and others) to do many tasks.
- State‑of‑the‑art test results: It scored 98.9% on LIBERO and 53.9% on RoboCasa, two well‑known robot simulation benchmarks, using only regular RGB video input.
- “Zero‑shot” transfer signals: The same model showed non‑zero success even on new robot‑task combinations it had never seen for that robot—like trying a new instrument for the first time and still playing a simple tune.
- Scalable training recipe: The unified action space and single sequence training let human data teach complex robots, reducing how much platform‑specific data is needed.
Why this matters:
- It proves that treating human movement as a universal “physical language” helps robots learn faster and adapt to new bodies.
- It shows one model can see, understand, and act together, rather than stitching separate systems.
What could this change?
- Faster deployment on new robots: Companies and labs could bring up new robot hardware with less custom data.
- More capable household and factory robots: Skills from one robot can spread to others, speeding up progress.
- Safer and more stable behavior: The model’s stability tricks help avoid weird or unsafe motions when sensors are noisy.
- Community progress: The team plans to open‑source models, training code, and real‑world deployment tools, lowering barriers for others to build on this work.
Key takeaways
Being‑H0.5 shows a practical path toward “one brain, many bodies” in robotics. By training on huge amounts of human hand videos and many different robots, using a shared action “grammar,” and designing a model that can think and move smoothly, the authors demonstrate strong, transferable robot skills—even across very different machines.
Knowledge Gaps
Knowledge gaps, limitations, and open questions
Below is a focused list of concrete gaps and unresolved questions that future work could address to strengthen, validate, and extend the paper’s claims.
- Unified Action Space specification: The paper does not formalize the unified action space (slot definitions, coordinate frames, units, invariances, and constraints). A clear algorithmic description, schema, and invertibility conditions for mapping human/robot controls into and out of this space are missing.
- Retargeting fidelity and kinematic mismatch: Quantitative analysis of retargeting error from MANO-derived human hand trajectories to diverse robot end-effectors (grippers, dexterous hands) is not provided, including sensitivity to differences in kinematics, reachability, compliance, contact friction, and force/torque limits.
- Action modality coverage: It remains unclear whether the unified action space supports torque/impedance control, force feedback, or haptic signals versus purely position/velocity control; the implications for contact-rich and compliance-critical tasks are unexplored.
- Mapping to non-anthropomorphic effectors: Generalization of human-centric action slots to non-hand tools (e.g., suction cups, scoops, specialized grippers) and to end-effectors with fundamentally different affordances is not evaluated or specified.
- Observation alignment and frames: How unified actions are grounded to object/world frames (absolute vs. relative commands, egocentric vs. exocentric coordinate choices) across datasets with unknown or inconsistent extrinsics is unspecified.
- Loss balancing and curriculum: The unified sequence modeling mixes text, human-motion, and robot-action losses, but the paper does not disclose loss weights, scheduling, or curriculum policies, nor ablate their effects on reasoning vs. control performance and cross-embodiment transfer.
- Mixture-of-Flow (MoF) design details: A precise architectural description (expert types, routing function, gating topology, training dynamics, regularization) and ablations comparing MoF to simpler baselines (single-flow head, MoE without flow, platform-specific heads) are absent.
- Manifold-Preserving Gating theory and validation: There is no formal definition or stability analysis of the gating mechanism, nor empirical stress tests to show it prevents off-manifold drift under perception ambiguity or distribution shift.
- Universal Async Chunking robustness: The method’s behavior under realistic latency/jitter, asynchronous sensing/control rates, and network delays is not quantified; stability and performance limits across embodiments with widely varying actuation profiles remain open.
- End-to-end latency and real-time throughput: Inference latencies, control frequencies, jitter statistics, and hardware requirements for real-time operation on high-DoF platforms are not reported, limiting reproducibility of low-latency claims.
- Emergent zero-shot transfer quantification: The “non-zero success rate” in cross-embodiment zero-shot is not characterized (absolute rates, tasks attempted, sample sizes, statistical significance, failure taxonomy), nor ablated to isolate contributing factors (data diversity vs. unified action vs. architecture).
- Safety and failure modes: The paper does not analyze failure cases (contact instability, object drop, self-collision, hardware stress) or detail safety constraints, safeguards, and recovery strategies during real-robot deployment.
- Sim-to-real mixture effects: While simulated data is capped at 26%, the impact of sim proportion on real-world performance, and techniques to mitigate domain gaps (randomization, dynamics calibration, vision realism), are not systematically studied.
- Depth/tactile benefits vs. RGB-only evaluation: The model is evaluated with low-resolution RGB, but the gains (or trade-offs) from adding depth, tactile, or multi-view inputs are not quantified—even though UniCraftor collects RGB-D and precise extrinsics.
- Dexterous manipulation coverage and metrics: The paper emphasizes dexterous hands but does not present task-specific dexterity benchmarks (precision pinch, in-hand rotation, tool use) or metrics (contact stability, slip, force control) demonstrating true high-DoF proficiency.
- Long-horizon planning evaluation: Although planning datasets are included, there is no closed-loop evaluation of long-horizon, multi-step tasks on real robots with metrics for plan correctness, subgoal sequencing, and recovery under partial failure.
- Multi-view fusion and calibration generality: UniCraftor relies on AprilTags for extrinsics; it remains unclear how the approach generalizes to tag-free environments, and how multi-view fusion is handled for datasets without reliable calibration.
- Human-video annotation reliability: The use of LLM-generated per-second and chunk-level annotations is not audited for consistency, correctness, or bias; the impact of annotation noise on policy learning and potential mitigation strategies are not reported.
- Hand pose estimation noise: Residual errors in HaWoR hand pose estimates (especially under occlusion, motion blur, and clutter) and their downstream effect on control policies are not quantified; robustness to estimate corruption remains untested.
- Data deduplication and downsampling: The 30% frame downsampling choice for robot data lacks analysis of temporal resolution trade-offs, especially for high-frequency control and contact events; impact on learning fine-grained dynamics is unknown.
- Scaling laws and data composition: There are no scaling-law analyses linking data size, embodiment diversity, and performance; optimal mixtures of human vs. robot data (and of sim vs. real) for target embodiments remain an open design question.
- Adaptation protocols for low-resource robots: The paper motivates rapid adaptation to new platforms but does not define or evaluate standardized few-shot/zero-shot adaptation protocols, data budgets, or fine-tuning strategies.
- Continual learning and catastrophic forgetting: How the model adapts to new embodiments or tasks without overwriting prior skills—especially balancing vision-language reasoning and action competence—remains unaddressed.
- Benchmark breadth and comparability: Evaluation focuses on LIBERO and RoboCasa and a limited set of real platforms; broader benchmarks (clutter, deformables, dynamic scenes, tool use) and standardized comparability (modalities, resolutions, action interfaces) are missing.
- Ethical, privacy, and licensing considerations: The paper does not discuss consent, privacy, and licensing issues around large-scale egocentric human data and third-party datasets, nor guidelines for safe open-source deployment on powerful robots.
- Generalization beyond manipulation: Although humanoids appear in the corpus, the unified action space’s applicability to locomotion, whole-body coordination, and mobile manipulation (navigation + manipulation) is not demonstrated.
- Resource and reproducibility details: Model size, training compute beyond “1,000 GPU-hours,” optimizer and hyperparameters, and exact data recipes are insufficiently detailed for full reproduction of reported results.
- Robustness to ambiguous or adversarial instructions: The model’s behavior under underspecified, conflicting, or adversarial language commands is not evaluated; safeguards and disambiguation strategies are unspecified.
- Failure analysis and debugging tools: There is no systematic framework for diagnosing cross-embodiment failures (mapping errors, perception issues, routing mistakes), nor tools for inspecting learned action slots or expert routing decisions.
