RoboticsTraining dataStory 07

One phone demo can be screened for many robot bodies

What changedThe system records an object trajectory and contacts rather than a human hand path, then tests whether each robot body can reproduce that record in simulation. A single phone capture could become auditable post-training data for different robots while refusing demonstrations their bodies cannot perform.

One phone-recorded pouring demonstration is replayed in simulation by several different robot bodies.

The useful part

Why it matters

A single phone capture could become auditable post-training data for different robots while refusing demonstrations their bodies cannot perform.

Keep in mind

Good to know

No policy has yet been trained from these records, and physical sim-to-robot success remains unproven.
