Precision Factory Assembly
One recording from this task family has been through the pipeline end to end and is published in full, with its checksum. That run is what the badge records.
What the brief covers
The brief specifies egocentric capture of manual assembly at a workstation: electronics assembly, micro-screwing and soldering, then quality checking and packing. It places capture on working hardware assembly lines in India. The parts are small and the finger motion is fast, which is why the camera is specified as global-shutter stereo at 90 frames a second: neither view carries rolling-shutter skew, which would otherwise differ between the two cameras and corrupt the depth.
The specification
| Capture device | Stereo Global-Shutter Head Rig |
|---|---|
| Camera | 2560x960 @ 90 FPS (Stereo) |
| Spatial tracks | 6-DoF Camera Trajectory (SLAM) & Sync IMU (400Hz) |
| Annotation | Tier 1 · Tier 2 · Tier 3 |
| Availability | Pipeline validated |
What a delivery carries
All three tiers apply, and the recording published under Sample shows each of them on real footage. At Tier 3 each hand carries 21 keypoints per sampled frame, and its confidence is the detector's score for its own left-or-right call, from 0.5 to 1. Every Clip lists the fields that were generated rather than observed, in its own derived-fields list. The rig's SLAM trajectory and 400 Hz IMU are streams of the rig itself, and no FH-Ego v1 field is read from them; how they travel with a delivery is set in the engagement. LeRobot v2.1 and HDF5 are the standard containers for a policy-training stack; Zarr v2 in the UMI layout and TFRecord with an RLDS-style step schema are written on request.
Recording it
On a working line, people at nearby stations come into frame. Their faces are blurred on every decoded frame before anyone here reviews the footage, and the stage fails closed: if blurring cannot run, no later stage reads the file. Capture on a line runs with the site's written permission, agreed before the first session. Each Capture Partner's own consent is four separate agreements on their phone; using the footage to train robot models is one of them, and a Clip whose partner declined it is refused from any training release.
What to know before you commission this
- This brief is specified around a stereo global-shutter head rig. Rig build and calibration are part of what a commissioned engagement covers.
- The pipeline validation behind this badge ran end to end on a real recording at 640×360 and 30 frames per second, and is published in full with its checksum. This brief's own capture specification is 2560×960 stereo at 90.
- The badge records what has been validated end to end: the pipeline. Rig build and Capture Partner recruitment are scoped with the engagement.
- The published recording is bimanual precision work at an industrial sewing workstation.
Sample
The one recording that has been through our pipeline end to end belongs to this brief, and it is published in full — video, annotation and checksum.
