Home / Data services / Annotation and labeling
Action segmentation, affordance masks, language captions, reward signals — at the bar your model deserves.
Annotation and labeling is the process of adding structured metadata to raw robotics data — action boundaries, affordance masks, natural-language captions, and reward signals — so your model knows what happened, where, and why it mattered.
Labeling robotics data requires domain expertise, not just clicking boxes. Our annotators are trained on manipulation, locomotion, and navigation tasks.
Why outsource labeling?
Your engineers should be iterating on architectures, not drawing masks. We scale annotation teams up and down to match your training cycles.
1,200 labels/hr per trained annotator.
48-hour turnaround on standard batches.
14 modalities supported out of the box.

Four label types that bridge raw capture to a training-ready dataset.
Frame-level action labels with start, end, and class for every clip.
Pixel-level masks of graspable, pushable, and contact regions.
Free-form and templated natural-language descriptions per scene.
Dense or sparse reward per timestep for RL and IRL pipelines.
Four stages that lock the bar before billable work and verify it after.
Acceptance criteria locked with your team. Edge cases documented in writing.
Operators pass a gold-set bar before producing billable labels.
Production labeling with daily QA review and same-day rejections.

COCO, CVAT, YOLO, custom JSON, ROS bag with annotation overlays, and RLDS for trajectory data. If you use an internal format, share the schema and we will build a converter.
Our baseline is 99.4% label accuracy across active programs. We achieve this through multi-pass review, consensus labeling on ambiguous frames, and a dedicated QA team that audits every batch before delivery.
Every label goes through automated validation checks, a human review pass, and a final QA audit. Batches that do not meet your agreed accuracy threshold are re-labeled at no additional cost.
Yes. Send us your label taxonomy, class definitions, and any edge-case guidance before the program starts. We build that into operator training and validation tooling.
Ambiguous frames are flagged in the delivery manifest with a confidence score. You choose whether to include them in training, discard them, or send them back for adjudication.
