How Claru Delivers Physical AI Data

Claru provides an end-to-end pipeline so physical AI teams can move from brief to training-ready data quickly.

01

Scope the Dataset

Define the target behaviors, environments, and label schema with your research team. We align on formats, enrichment layers, and success criteria before capture begins.

02

Capture Real-World Data

Activate the collector network, teleoperation runs, or game-based capture to gather the exact clips your model needs.

03

Enrich Every Clip

Generate depth maps, pose, segmentation, and optical flow in batch. Cross-validate signals to ensure aligned training inputs.

04

Expert Annotation

Specialized annotators label action boundaries, affordances, and intent using project-specific guidelines and QA checks.

05

Deliver Training-Ready

Ship datasets in WebDataset, HDF5, RLDS, or your native format with manifests, checksums, and datasheets.
