OSMO: Open-Source Tactile Glove for Human-to-Robot Skill Transfer (2512.08920v1)
Abstract: Human video demonstrations provide abundant training data for learning robot policies, but video alone cannot capture the rich contact signals critical for mastering manipulation. We introduce OSMO, an open-source wearable tactile glove designed for human-to-robot skill transfer. The glove features 12 three-axis tactile sensors across the fingertips and palm and is designed to be compatible with state-of-the-art hand-tracking methods for in-the-wild data collection. We demonstrate that a robot policy trained exclusively on human demonstrations collected with OSMO, without any real robot data, is capable of executing a challenging contact-rich manipulation task. By equipping both the human and the robot with the same glove, OSMO minimizes the visual and tactile embodiment gap, enabling the transfer of continuous shear and normal force feedback while avoiding the need for image inpainting or other vision-based force inference. On a real-world wiping task requiring sustained contact pressure, our tactile-aware policy achieves a 72% success rate, outperforming vision-only baselines by eliminating contact-related failure modes. We release complete hardware designs, firmware, and assembly instructions to support community adoption.

OSMO: Open-Source Tactile Glove for Human-to-Robot Skill Transfer
Introduction and Motivation
The paper "OSMO: Open-Source Tactile Glove for Human-to-Robot Skill Transfer" (2512.08920) introduces the OSMO tactile glove, an open-source, wearable device enabling the collection of in-the-wild human demonstrations enriched with high-fidelity tactile information. Existing datasets and robot learning pipelines predominantly rely on visual data, which is insufficient for capturing the nuanced contact forces involved in dexterous manipulation. OSMO addresses foundational limitations of video-only approaches by providing both shear and normal force feedback via 12 three-axis magnetic tactile sensors distributed across the fingertips and palm. This facilitates the direct transfer of contact-rich human skills to robotic platforms, significantly reducing embodiment gaps and obviating the need for vision-based force inference.

Tactile Glove Hardware and Sensing Architecture
OSMO's hardware design emphasizes unrestricted human dexterity, extensive hand coverage, compatibility with mainstream hand-tracking platforms, and direct deployability on both human and anthropomorphic robot hands. The glove employs distributed magnetic sensor assemblies, each comprising dual 3-axis magnetometers and a soft, axially-magnetized elastomer. MuMetal shielding and differential signal measurement strategies mitigate inter-taxel crosstalk, a critical challenge when scaling to dense sensor arrays in close proximity.

Empirical crosstalk characterization confirms the efficacy of these mitigation strategies, with average noise reductions of up to 57% compared to single magnetometer baselines and up to 18% over dual-magnetometer configurations. The system sustains a broad force sensing range (0.3 N–80 N), providing sufficient dynamic range and signal-to-noise for manipulation tasks without compromising user dexterity.

Hand Tracking Compatibility and Human-Robot Embodiment Bridging
OSMO is engineered for compatibility with state-of-the-art hand-tracking solutions commonly used in AR/VR and stereo video-based setups. Its low-profile, skin-toned appearance, and non-interfering sensor architecture ensure minimal visual domain shift when using conventional vision models.
Figure 4: OSMO integration with diverse hand-tracking platforms, including AR/VR headsets, RGB cameras, and Manus gloves, enabling robust pose estimation even under occlusion.
Through a shared glove architecture, the visual and tactile representation gap between human demonstrators and robot effectors is minimized, significantly simplifying policy transfer. This shared interface enables training with only human demonstration data for direct robot deployment.

Glove2Robot Policy Pipeline
The Glove2Robot pipeline leverages OSMO-collected demonstrations to train contact-rich policies for robots using exclusively human data. RGB and tactile glove data are synchronized and mapped to robot joint commands via kinematic retargeting, facilitated by off-the-shelf inverse kinematics solvers in MuJoCo. Fingertip and wrist positions are robustly estimated from vision and depth data, allowing for temporally-consistent mapping to robot joint trajectories.

Policy learning employs a diffusion policy architecture conditioned on multimodal features: DINOv2 for vision, MLPs for tactile and proprioceptive states, and U-Net-based denoising for action prediction. Normalization and differential magnetometer processing ensure tactile features are salient and compatible with neural representation learning.
Empirical Results and Policy Performance
On a demanding wiping task—requiring sustained contact pressure and fine force modulation—the tactile-aware policy trained with OSMO achieves a 71.7% average success rate, markedly outperforming vision-only (55.8%) and proprio-only (27.1%) baselines. These strong numerical results highlight the critical role of tactile feedback in eliminating contact-related failure modes such as loss of sponge grasp and insufficient contact pressure.
Figure 7: Rollouts of OSMO-trained robot policies showcase successful contact-rich manipulation and detail failure modes in policies lacking tactile feedback.
Key findings include:
- Eliminated failure modes relating to contact maintenance, not seen in vision-only pipelines.
- Smoother trajectory execution and higher consistency in force application.
- Direct correspondence between human and robot tactile modalities, reducing the need for complex visual post-processing.
Implications and Future Perspectives
OSMO demonstrates robust transfer of human tactile demonstration to robotic platforms without reliance on robot-side data collection, substantially lowering adoption barriers for contact-rich policy learning. Open-sourcing hardware, firmware, and assembly methods facilitates broad community uptake and enables further methodological exploration, such as joint tactile-IMU fusion for occlusion-robust pose estimation and denser sensor arrangements for fine-grained manipulation.
The paper identifies promising avenues for future research:
- Improved spatial resolution and wraparound coverage at the fingertips for enhanced contact localization.
- Exploiting onboard IMUs for occlusion-aware hand pose reconstruction in visually challenging settings.
- Algorithmic generalization to bimanual or multi-fingered tasks, scaling tactile skill transfer to complex manipulation.
- Policy generalization under visual domain shifts driven by tactile feedback.
Continued advancements in tactile sensing, cross-modal representation learning, and simulation-to-real transfer are anticipated to accelerate the deployment of dexterous robots capable of executing complex, contact-dependent tasks in unstructured real-world environments.
Conclusion
OSMO establishes a practical and technically rigorous solution for human-to-robot skill transfer in contact-rich manipulation scenarios. Its open-source tactile glove design, advanced crosstalk mitigation, and multimodal policy learning pipeline substantiate the claim that high-fidelity tactile sensing is indispensable for bridging the gap between visual demonstration and deployable robotic dexterity. The system's superior empirical performance and extensibility set a strong precedent for future research in tactile-augmented robotic learning, scalable skill transfer, and hardware-software co-design in robotics.

What this paper is about
This paper introduces OSMO, a thin, wearable “tactile” glove that acts like a skin for both people and robots. It captures how hard and in what direction the hand is pressing or sliding on objects. The big idea is to let robots learn hands-on skills by “watching and feeling” how humans do tasks, not just by looking at videos. The team shows that a robot can learn a contact-heavy task—wiping a whiteboard—using only human demonstrations collected with this glove, and then perform the task successfully using the same kind of glove on its own hand.
The main questions the researchers asked
- Can a simple, flexible glove collect the important “feel” information (forces) that videos miss?
- Can a robot learn a real, contact-rich skill (like wiping with steady pressure) using only human data gathered with this glove?
- If both the human and the robot wear the same glove, does it make learning and transferring skills easier and more reliable?
How the glove and learning system work (in everyday language)
Think of the glove as a lightweight “smart skin”:
- What the sensors feel: Each fingertip and parts of the palm have tiny magnetic sensors that can detect:
- Normal force: pushing straight in, like pressing a button.
- Shear force: sideways force, like rubbing or sliding when you wipe.
- Why force matters: In many tasks, you can’t tell by sight how hard someone is pressing. Two videos can look the same even if one person presses lightly and another presses firmly. The glove captures that hidden “feel” information.
How the sensing works, simply:
- Imagine a compass needle moving when a magnet gets close. The glove uses a similar principle: small magnetic patches deform when pressed, and nearby magnet sensors measure changes. From that, the system infers forces in three directions.
- Preventing “sensor chatter” (crosstalk): With many magnets close together, sensors can “hear” their neighbors and get noisy. The team reduced this interference in two ways:
- MuMetal shielding: like putting walls between rooms so sounds don’t leak.
- Differential sensing: using two magnetometers per spot and subtracting their readings, similar to noise-canceling headphones that remove background hum.
- These steps made the signals much cleaner when fingers moved or neighboring sensors were pressed.
Collecting human demonstrations:
- A person wears the glove and performs the task (wiping) while a camera records the scene.
- Hand pose (where the fingers and wrist are) is estimated from video using existing hand-tracking tools. When depth is available, they refine positions so they’re more accurate.
Turning human motion into robot commands:
- The robot has a hand similar in size to a human’s. The system uses inverse kinematics (think of it as solving a puzzle that tells the robot what joint angles it needs to place its fingertips where the human’s were).
- The team pairs the human’s video and glove data with the robot’s retargeted joint positions to build a training set.
Teaching the robot (the policy):
- The robot learns a “policy,” which is a rule for what to do next based on what it sees and feels.
- Inputs during training: the human’s video images and tactile signals from the glove; targets are the robot joint positions computed from the human movements.
- The learning model is a “diffusion policy.” In simple terms, it learns to plan smooth action sequences by starting with a rough guess and repeatedly refining it—like starting with a blurry path and sharpening it step by step.
- At test time, the robot wears the same glove, looks through the same kind of camera, and uses its own tactile readings to guide its motions.
What the researchers found and why it matters
Key results on a real robot wiping task:
- The robot needed to keep steady pressure while wiping—a perfect case where “feel” is crucial.
- Policies tested:
- Only robot’s own joint info (no vision or touch): about 27% success.
- Vision + joints (no touch): about 56% success.
- Vision + joints + tactile glove: about 72% success.
- Why the tactile glove helped:
- With touch, the robot pressed with more consistent pressure and avoided losing grip on the sponge.
- Vision-only methods often failed because the camera can’t tell exactly how hard the robot is pushing.
Other important findings:
- Using the same glove on humans and robots reduces the “appearance gap,” so the robot doesn’t need fancy image editing to translate human videos into robot-compatible views.
- The glove’s crosstalk-reduction design made multi-sensor data more reliable, which is important when many sensors are packed into a small glove.
What this could change going forward
- Better robot skills from everyday human demos: Because the glove is open-source and designed to work with common hand trackers and cameras, more people can collect useful data. This could speed up robots learning hands-on tasks at home, in labs, or in factories.
- Force-aware learning becomes practical: Adding “feel” to video makes it easier for robots to learn tasks that depend on pressure and friction, like wiping, scrubbing, tightening lids, or handling delicate objects without crushing them.
- Easier human-to-robot transfer: Sharing the same glove for humans and robots shrinks the gap between how humans perform tasks and how robots should perform them.
Quick takeaways
- What’s new: A low-profile, open-source tactile glove that senses both push and slide forces and works on both human and robot hands.
- Why it’s needed: Videos alone can’t tell how hard you’re pressing; touch fills in that missing piece.
- What it proved: A robot trained only on human glove data can perform a real, contact-heavy task better than vision-only methods.
- Why it’s exciting: It opens the door to teaching robots practical, touch-dependent skills using simple, widely available tools.
Knowledge Gaps
Knowledge gaps, limitations, and open questions
Below is a single, concrete list of what remains missing, uncertain, or unexplored, framed so future researchers can act on it:
- Absolute force calibration: the policy and analyses use raw magnetic flux (µT); there is no per-taxel calibration to 3D force (N) across the glove, nor characterization of nonlinearity, hysteresis, temperature drift, or rate dependence under typical manipulation.
- Coordinate alignment: the paper does not define or validate mappings from each taxel’s XYZ axes to the human/robot hand frames, making shear vs. normal force interpretation and cross-embodiment transfer ambiguous.
- Crosstalk under realistic human use: crosstalk mitigation is evaluated on a robot hand with simple motions; it remains unknown how well shielding + differential sensing suppresses interference during complex, rapid human manipulation, full-hand contact, and multi-finger coordination.
- Z-axis noise trade-off: MuMetal reduces XY noise but increases Z-axis noise; there is no algorithmic compensation, adaptive filtering, or design alternatives explored to recover Z-axis fidelity.
- Environmental magnetic interference: there is no measurement or mitigation for external magnetic disturbances (robot motors, ferromagnetic objects, tools, variable Earth field) or soft-/hard-iron effects during typical lab/household use.
- Latency and bandwidth: tactile sampling at 25 Hz and action updates at 2 Hz are low for contact-rich control; the end-to-end latency budget (sensing-to-actuation) is not quantified, nor are higher-rate control or reflex loops evaluated.
- Durability and wearability: long-term stability of soft magnets, adhesives (Silpoxy), tinsel wires, and MuMetal under repeated donning/doffing, sweat, moisture, impacts, and cleaning is not assessed; no tests of glove comfort, fatigue, or skin irritation.
- Manufacturability and accessibility: the requirement for pulse magnetization at 2 kV and waterjet-cut shielding may limit replication; low-cost fabrication alternatives, QA tolerances, and community reproducibility studies are missing.
- Sensor layout optimization: fingertips have one taxel each; there is no paper of denser, wraparound, or multi-taxel designs to localize contact points, measure slip, or capture distributed pressure across phalanges and palm.
- Palm utility: palm sensors are omitted for the wiping task; the value of palm coverage for stabilization, power grasps, and varied tasks remains unevaluated, including taxel placement trade-offs.
- Onboard IMU fusion: each PCB includes an IMU, but the paper does not integrate IMU signals with vision/magnetometers for occlusion-robust hand pose or magneto-inertial tactile fusion; fusion architectures and calibration procedures are open.
- Hand pose accuracy: there is no quantitative error analysis of the vision-based hand pose pipeline (SAM2+HaMeR+stereo) under occlusion, motion blur, depth ambiguity, and specular surfaces, nor a paper of its impact on retargeting and policy outcomes.
- Egocentric, in-the-wild deployments: while compatibility with AR/VR devices is shown visually, the pipeline is not demonstrated end-to-end with moving egocentric cameras (extrinsic drift, head motion), nor is robustness to out-of-lab environments tested.
- Calibration robustness: the pipeline assumes known intrinsics and extrinsics; sensitivity analyses (to calibration error, time-varying extrinsics, or camera repositioning) and auto-calibration strategies are absent.
- Safety in contact tasks: collision checks were disabled for fingertips and wrist against the ground; contact-aware IK, compliance control, and safety constraints for deployment are not addressed.
- User diversity and fit: the dataset’s number of demonstrators is not specified; generalization across hand sizes, glove fit, wearing variability, and left vs. right hand use is unexplored.
- Object/environment diversity: generalization is not tested across sponges, surfaces (rough/smooth/wet), friction/stiffness variations, lighting changes, or different wiping targets beyond two marker patterns.
- Task breadth: only one unimanual wiping task is evaluated; multi-finger dexterity, in-hand manipulation, tool-use, bimanual coordination (two gloves), and task switching are open.
- Modality ablations: there is no tactile-only baseline and no systematic ablation of each modality’s contribution (vision, proprioception, tactile) or modality-gating strategies under occlusion.
- Visual encoder adaptation: DINOv2 is frozen; effects of fine-tuning, domain adaptation to robot viewpoints, and robustness to background/camera changes are untested.
- Tactile representation learning: tactile inputs are raw differential µT; pretraining (e.g., contrastive touch-to-touch), supervised force mapping, contact-state/slip classifiers, or temporal tactile transformers are not explored.
- Action frequency and control design: chunked diffusion actions at 2 Hz may be too coarse for pressure regulation; hierarchical controllers, high-frequency tactile servoing, and hybrid reflex/planning strategies are not evaluated.
- Dataset scale and efficiency: 140 demonstrations (~2 hours) are used; scaling laws, data augmentation, and data efficiency gains from tactile signals (vs. vision-only) are not quantified.
- Cross-robot transfer: deployment is shown on the Ability Hand; portability to other anthropomorphic hands (Inspire, Sharpa), required mechanical adaptations, and per-robot sensor calibration are not demonstrated.
- Taxel selection ablations: the paper uses only five fingertip taxels during training/deployment; systematic ablations on which taxels matter (including palm) and how many are needed for performance are missing.
- Success metrics: pixel erasure is a coarse proxy for contact quality; pressure consistency metrics, contact duration, slip events, and sponge retention are not quantified; statistical significance and confidence intervals over more rollouts are absent.
- Failure analysis tooling: qualitative failures (insufficient pressure, sponge loss) are noted but not automatically detected or categorized; event detection pipelines and corrective behaviors are open.
- Interference with other wearables: Manus glove compatibility is claimed but not stress-tested; rigorous electromagnetic and mechanical interference studies with common wearable systems and robot actuators are lacking.
- Power and connectivity: the glove requires USB-C tethering; wireless streaming, battery operation, and synchronization robustness (clock drift, packet loss) in mobile, in-the-wild settings are unaddressed.
