Robots and physical AI ultimately learn from data. Teleoperation logs collected by people driving real robots, synthetic data churned out by physics engines in simulators, tactile data capturing the pressure and slip at a fingertip, and behavior data accumulated at national scale. A robot foundation model's competence is decided by the scale and quality of this data. This hub gathers the writing on the data robots learn from itself — how datasets are structured and released, their quality and standards, and provenance, the piece still missing.

Pebblous reads this data through one lens: not making more data, but making proof-attached data. Most public datasets keep the frames, states, and actions but discard the proof — contact force, generation history, physical consistency. Filling that gap with data-quality diagnosis, refinement, and certification is the work of DataClinic.

Six Famous Robot Datasets, One Shared Format?

A landscape comparing DROID, Open X-Embodiment, GR00T, RoboCasa, MimicGen, and LIBERO by scale, license, and format. Collection splits six ways, but distribution converges on a single LeRobot format — and all six leave provenance unrecorded. (Overview of this hub.)

Robot Demonstration Data From a Single Photo

Kyung Hee University's PRISM generates digital demonstration data from a single photo of a workspace plus a natural-language instruction, sidestepping the data bottleneck in robot policy learning.

When Footage Becomes a Simulator Asset

NVIDIA NuRec reconstructs real footage into simulator assets via 3D Gaussian Splatting — a real-to-sim pipeline that moves reality into the simulator.

Synthesizing Robot Training Data From Human Hand Motion Alone

Alibaba DAMO Academy's RynnWorld-Teleop synthesizes robot-perspective demonstration video from human hand-motion streams alone, without a physical robot.

Ai2 Released 720 Hours of Robot Training Data With the Model

Ai2's MolmoAct 2 released not just model weights but 720 hours of bimanual-manipulation robot data, code, and evaluation in full — a new bar for open robot data.

AgiBot Records Even the Feel of Contact

AGIBOT WORLD 2026 Theme 2 records not successful demos but the texture of contact — misses, collisions, slips — with tactile sensors. The physics vision alone can't teach.

AgiBotWorld Labels Even the Robot's Fumbles

AgiBotWorld 2026 doesn't discard failed robot demos; it annotates them with error_cause and restorable fields — a rare case of keeping failure history as data.

The Tactile Data Humanoid Capital Skipped

Humanoid robots and foundation models drew billions, but tactile data capturing pressure and slip drew only millions. The gap in data that capital passed over.

Etching Physical Law Into a Robot's Imagination

RoboScape enforces physical validity from the moment synthetic data is generated, matching the performance of 200 real videos with 200 synthetic ones.

Is the Generated Video Physically Correct?

A dissection of the technique family that audits, after the fact, whether video from Cosmos and Sora is physically correct — how to verify the physical consistency of synthetic data.

Giving Robots Eyes — How 3DGS Changes Synthetic Data

Combining 3D Gaussian Splatting with NVIDIA Isaac Sim reshapes the robot synthetic-data pipeline — the frontier of synthetic data generation for VLA training.

The Digital World That Teaches Robots — NVIDIA Isaac Sim and GR00T

How Isaac Sim delivers 1,000x faster training and GR00T Blueprint generates 780K robot trajectories in 11 hours — the mechanics of synthetic data mass production.

Once the Standard Is Laid, Who Certifies Data Quality?

With OpenUSD 1.0 standardization, NVIDIA Omniverse became the data-standard layer for physical AI. Even at 780K synthetic trajectories, the quality-assurance gap remains.

Robots Multiply, So Why Doesn't Experience Accumulate?

Humanoid robots are surging, yet robot experience isn't accumulating. Robot data standardization seen through the ISO/WD 26264-1 draft released in June 2026.

The Battleground of Physical AI Is Behavior Data

The government named the bottleneck of physical AI not chips or models but "behavior data," and why it plans to build behavior-data training centers across five regions first.

The Data Gap in Korea's ₩16 Trillion Physical AI Policy Finance

Korea's financial and industry ministries allocated ₩16 trillion in physical-AI policy finance across six industries. Money flows to factories and hardware, but the data gap remains.

However much the data robots learn from grows, if there's no evidence that the data is physically correct, the trust bottleneck stays. See how Pebblous approaches proof-attached data at DataClinic, where data-quality diagnosis, refinement, and certification come together.
