# Foundation models and physical robots are entering a co-development loop where deployed robots generate training data that improves models which improve robot capabilities creating a flywheel that accelerates nonlinearly past fleet-size thresholds

The pattern that drove internet AI from narrow applications to general capability — data flywheels where deployed products generate training data that improves models that improve products — is beginning to replicate in physical robotics. The evidence is early but structurally significant.

**Foundation models are crossing from language to action.** Google DeepMind's RT-2 (Vision-Language-Action model) was the first to directly output robotic actions as text tokens from web knowledge, doubling performance on novel unseen scenarios from 32% (RT-1) to 62%. This demonstrates cross-task transfer with minimal robot-specific training — web-scale knowledge about objects and their properties transfers to physical manipulation without explicit programming.

**Multi-robot datasets are enabling positive transfer.** The RT-X project (January 2026 public release) combines data from 22 different robots across 21 institutions covering 527 demonstrated skills. The key finding: a large-capacity model trained on this diverse dataset shows positive transfer — it improves capabilities across multiple robot platforms, meaning data from one robot type helps others. This is the structural prerequisite for a data flywheel: marginal data has increasing rather than diminishing returns when it comes from diverse embodiments.

**Sim-to-real transfer is approaching zero-shot viability.** The Allen Institute's MolmoBot achieves manipulation transfer across multiple platforms without real-world fine-tuning, outperforming even models trained on large-scale real-world demonstration data (pi-0.5). AutoMate achieves 84.5% real-world assembly success with simulation-only training. These results suggest that the data bottleneck can be partially bypassed through simulation, expanding the effective training set beyond what physical fleet deployment alone could generate.

**The flywheel is beginning to turn in production.** Universal Robots and Scale AI launched UR AI Trainer (March 2026 at GTC), creating an integrated pipeline for training, deploying, and improving VLA models on production robots. The Scanford project demonstrated the flywheel concretely: 2,103 shelves of real-world robot-collected data improved foundation model performance from 32.0% to 71.8% on multilingual book identification and from 24.8% to 46.6% on English OCR. The robot's own operation generated training data that made the robot better.

**The threshold question:** When does the flywheel reach escape velocity? Internet AI flywheels compound because marginal data collection cost is near zero (users generate it passively). Physical data collection costs are orders of magnitude higher — each training episode requires a real robot, real objects, real time. The co-development loop will compound nonlinearly only when fleet sizes cross data-sufficiency thresholds — likely tens of thousands of deployed robots generating continuous operational data. Below that threshold, the flywheel turns slowly. Above it, capability gains should accelerate in a pattern similar to LLM scaling laws but on a different timeline.

## Challenges

The internet-to-physical data flywheel analogy may be fundamentally flawed. Web data is cheap, abundant, and diverse by default. Physical robotics data is expensive, slow to collect, and limited by the specific environments where robots are deployed. A warehouse robot fleet generates warehouse data — it doesn't naturally generate the diversity needed for general manipulation capability. The RT-X positive transfer result is promising but comes from a curated research dataset, not from production deployment. Whether production-deployed robots generate data diverse enough to drive general capability improvement (rather than narrow task improvement) is an open empirical question.

Additionally, the 62% success rate on novel tasks (RT-2) and 84.5% on assembly (AutoMate) remain far below the reliability required for unsupervised deployment. If deployed robots fail frequently, they generate failure data (valuable for training) but also economic losses (problematic for fleet expansion). The flywheel may stall in the valley between "good enough to deploy" and "good enough to generate quality training data without excessive human oversight."

Relevant Notes:
- [[general-purpose robotic manipulation remains the binding constraint on physical AI deployment because sensor fusion compliant control and tactile feedback must solve simultaneously]] — the co-development loop is the mechanism by which the manipulation constraint may ultimately be overcome
- [[the atoms-to-bits spectrum positions industries between defensible-but-linear and scalable-but-commoditizable with the sweet spot where physical data generation feeds software that scales independently]] — the robotics data flywheel IS the atoms-to-bits sweet spot: physical robots generate data that feeds software improvement
- [[three conditions gate AI takeover risk autonomy robotics and production chain control and current AI satisfies none of them which bounds near-term catastrophic risk despite superhuman cognitive capabilities]] — the co-development loop accelerates the timeline for closing the robotics condition
