Scope of work
Twelve tasks across two divisions, recorded on live jobsites and in occupied buildings. Open any line item to see what the camera captures and what a model can learn from it.
Active construction site
5 line items03.01Site cleanup & debris removalBroom, shovel, wheelbarrow, bins
What we record
Sweeping, sorting scrap by material, loading bins and wheelbarrows, clearing walkways between active work zones.

Site conditions
Varied equipment brands and layouts from one visit to the next.
06.06Thermostat & control wiringPrecision screwdriver, wire stripper, tester
What we record
Removing faceplates, identifying and labeling low voltage wires, terminating them and mounting the new control.
What a model learns
Fine manipulation of small parts and reading color coded conductors.
Site conditions
Occupied homes and offices, close range work at eye level.
06.07Outlet & fixture wiringStripper, pliers, voltage tester, driver
What we record
Testing for power, stripping and bending conductors, terminating devices and mounting outlets and light fixtures.
What a model learns
Wire dexterity and the safety check that comes before every step.
Site conditions
Boxes in walls and ceilings, ladders, mixed lighting.
Field conditions you can't stage
A robot on a jobsite meets dust, gloves and a crew that moved the ladder. Lab footage doesn't show that. Ours is recorded where the work actually happens, so these conditions come built in.
Gloved hands
Work gloves change how a grip looks and how fingers are tracked. Your model sees both.
Dust & debris
Particles in the air, residue on surfaces and lenses, scrap underfoot.
Tight spaces
Under sinks, inside walls, behind units: partial views where only one hand fits.
Changing light
From open slabs in full sun to unlit rooms lit by a work lamp.
Shared workspace
Other trades crossing the frame, handing over tools, working on the same wall.
Real tool wear
Worn bits, bent blades and taped handles. The tools a robot will actually pick up.

Capture kit
The bill of materials for every session. Video is standard. The other signals are added per project, recorded in sync with the footage.
| Mark | Item | What it records | Why it matters on a jobsite | Status |
|---|---|---|---|---|
| K-1 | Head-mounted camera | First person video from the worker's eye line, hands and tool in frame. | It matches the viewpoint of a robot's own camera, which a fixed or third person angle can't do. | Standard |
| K-2 | Depth | Distance to surfaces and objects, aligned to each video frame. | Studs, pipes and boxes sit at different depths inside the same wall. | Per project |
| K-3 | Motion & pose (IMU) | Head, wrist and arm movement through every step of the task. | Separates a careful cut from a fast one when the video looks the same. | Per project |
| K-4 | Force & tactile glove | Grip pressure and contact force at the fingertips and palm. | Torque on a fitting or resistance in a drain is felt before it is seen. | Per project |
| K-5 | Audio | Ambient and task sound: a drill seating a screw, a cable catching in a pipe. | Sound often signals that a step is complete. | Per project |
Resolution, frame rate and sensor configuration are set in the project spec.
Project schedule
A typical pilot, from first call to first delivery. Capture and labeling overlap, so you start receiving data while recording is still underway.
The submittal
What lands in your bucket: clips with their signals, metadata and the label layers your pipeline expects. The manifest below is an illustrative example, not a client deliverable.
Step segmentation
Each clip split into named steps with start and end times: shut off, drain, disconnect, swap.
Hand pose
Keypoints for both hands, tracked through gloves and partial occlusion.
Tools & materials
Boxes and tracks for every tool and part in use, with the moment of contact marked.
Scene structure
Walls, studs, fixtures and openings labeled for spatial context.

Site safety & consent
Recording never comes before the work or the people doing it.
PPE on every session
Contributors record in the protection the task requires. Safety comes first, the shot second.
Signed consent
Every contributor signs before recording and is paid for the hours they deliver.
Privacy by default
Faces and identifying details of bystanders are blurred before delivery.
Site authorization
We record only where the site owner or contractor has approved it.
Who's on site
Crew Hands is a product of Vintti, a staffing company that has connected Latin American talent with companies in the US and Canada since 2022.
Recruiting is what we know. We find skilled people, check their work and keep them engaged over months, not days. Crew Hands applies that to physical AI: we work with tradespeople across the region and the sites they already work on, and turn their everyday jobs into training data.
Latin America builds with a wide mix of methods, from poured concrete and block to steel stud and drywall, often on the same street. A model that has seen that range is better prepared for any site it lands on.

The questions we usually get before a first call.
RFI-001Who records the footage?
Working tradespeople: cleanup crews, drywallers, painters, plumbers, HVAC technicians and electricians. They record the jobs they already do, with our kit, after training and signing consent.
RFI-002Can you record a task that isn't on the list?
Yes. The twelve tasks are where we are recording today. If your model needs another trade or a specific procedure, send the spec and we'll tell you how quickly we can staff it.
RFI-003How do you check quality?
Every session is reviewed against the spec: framing, hands in view, task completed, signals in sync. Clips that fail are re-recorded, not delivered.
RFI-004Can we start small?
Most clients start with a pilot on one or two tasks. It lets you test the data in your pipeline before committing to volume.
RFI-005Who owns the data?
Rights and exclusivity are defined in each contract. Data collected for a project can be delivered for your exclusive use.
RFI-006Which labels can you deliver?
Step segmentation, hand pose, tool and object tracking and scene structure are the most common. We follow your schema and output format.
Send us your spec. We'll send a bid.
