What we have learned capturing people with ordinary cameras and teaching their motion to a humanoid: the data sources, what camera count changes, what breaks in retargeting, and how the capture works, with live figures on real footage.

Robot learning
ExplainerHuman motion data for humanoid robots: the six sources and what each one measuresWhere humanoid robots get human motion data: teleoperation, handheld grippers, first-person headcam video, mocap studios, single-camera estimates and markerless multi-view capture compared by what each records, where it works and how accurate it is.ResearchHow much does camera count matter when a humanoid learns from video?We trained a Unitree G1 tracking policy on the same motion captured three ways: a 27-camera mocap dome, three cameras, and one camera. Three cameras matched the dome; one camera added 3–6 cm of keypoint error.EngineeringRetargeting human motion to a Unitree G1: what breaks and how to check itFive failure modes we hit retargeting captured human motion to a Unitree G1 humanoid, from start-up transients to floating feet, and the checks that catch them before training.
How the capture works
Explainer · 4 min · 2 live figuresHow to sync cameras without timecodePhones and action cameras share no clock. How multi-camera footage is lined up from sound and then from the subject’s own motion, how precise each step is, and when it fails. Two live figures.Explainer · 4 min · 3 live figuresOne camera vs. threeWhy a single camera can only estimate 3D motion, what a second camera measures, and what a third adds: fewer blind spots and a built-in accuracy check. Shown live on a real sprint.EngineeringWhy handheld video broke our camera solve, and the one setting that fixed itOur 3D replays from a single handheld phone took 6 to 10 minutes because the camera-path solve failed about 3 runs in 10, nondeterministically. What we ruled out, what the cause was (rotation-dominated video and a robust-loss scale), and the fix: 3 minutes, first try.
