For robots operating in the physical world, seeing an object is only the beginning. A robot must also understand how far away it is, where
Egocentric video, hand pose, gaze tracking, and force gloves for VLA pre-training.
Human demonstration is the process of a trained operator physically performing a task — grasping, pouring, assembling, navigating — while wearable sensors capture hand pose, gaze direction, body motion, and egocentric video. The resulting dataset teaches a policy how a human actually solves the task, not how a script approximates it.
Collecting demonstration data in-house means recruiting skilled operators, sourcing sensor rigs, building a logging pipeline, and running QA across thousands of episodes. We compress that into a managed program.
Why outsource demonstrations?
Your research team should be training models, not managing capture sessions. We handle recruitment, hardware, and quality so you get clean episodes on schedule.
50,000+ hours collected to date.
40 Hz hand pose tracking across all rigs.
3 continents of operator coverage.

FAQ
Teleoperation uses a control interface — the operator never touches the robot. Human demonstration captures natural human motion directly, which is then used to train imitation learning policies. Both produce trajectory data but from different sources.
Operators are briefed on task objectives but not scripted on exact movements. This produces natural variation in approach and execution — which is exactly what imitation learning needs to generalize.
Our operator network spans diverse demographics, hand sizes, grip strengths, and experience levels. If your task requires a specific operator profile — handedness, physical dimensions, domain expertise — we can filter for it.
Every demonstration is reviewed against a task specification before acceptance. Outliers are flagged and sent back for re-capture. Inter-operator consistency metrics are included in every delivery report.
