Shift 01 · Manufacturing data for physical AI

Data from the floor, not the lab.

Mill Data sends cameras onto real shop floors across Latin America. Welders, machinists, assemblers and mechanics record the job the way they actually do it. You get the footage labeled and ready to train on.

MD-200 · Why real shops

The floor teaches things a lab forgets

A demo cell is clean, well lit and forgiving. A factory isn't. If your robot is headed to the second one, it should learn there.

01

Two hands, one job

Holding a part with one hand while the other drives a tool. Bimanual coordination is in almost every clip.

02

Tools that push back

Torque on a wrench, drag on a grinder, the catch of a thread. Paired force data shows what video alone hides.

03

Long jobs, strict order

A brake job is forty steps. Skip one and the car comes back. Clips keep the whole sequence, start to finish.

04

The fix, not just the task

Flash that didn't trim, a weld that needs a second pass. We keep the recoveries, because robots need those most.

05

Shop-floor conditions

Glare off sheet metal, coolant mist, gloves, ear protection, a forklift crossing the frame.

06

Machines with history

Worn fixtures, taped handles and controls from three decades. The equipment a robot will actually meet.

MD-300 · Capture kit

What the kit picks up

Video on every job. The rest gets bolted on per project and runs on the same clock.

RefSignalWhat it recordsStatus
S-1Egocentric videoHead-mounted, hands and tool in frame.Standard
S-2DepthPer-frame distance to parts, fixtures and machine surfaces.Per project
S-3Motion & poseIMU on head and wrists, through every step.Per project
S-4Force & tactileGrip pressure and contact force at fingers and palm.Per project

Resolution, frame rate and sensor setup are fixed in the project spec.

MD-400 · Process

How a run goes

Four stops between your first call and your first batch.

01

Spec

You send tasks, hours, signals and a label schema. We reply with scope, timeline and price.

02

Staff

We match shops and operators to the spec. Everyone signs consent and trains on the kit.

03

Capture

Operators record their normal work. Each session is reviewed against the spec the same day.

04

Deliver

Clips ship in batches as they pass QA, labeled to your schema, in your format.

MD-500 · Deliverable

The shift report

What you receive for every clip. The file below is an illustrative example, not client data.

  • L-1

    Step segmentation

    Each clip split into named steps with start and end times: tack, root pass, fill, cap.

  • L-2

    Hand pose

    Keypoints for both hands, tracked through gloves and partial occlusion.

  • L-3

    Tools & parts

    Boxes and tracks for every tool and workpiece, with the moment of contact marked.

  • L-4

    Station layout

    Fixtures, machine surfaces and bins labeled for spatial context.

MD-600 · Safety & consent

House rules

These are people's workplaces. We act like guests.

Rule 1

PPE or no recording

Operators wear what the task requires. If it isn't safe, it isn't filmed.

Rule 2

Signed consent, paid hours

Every contributor signs before recording and is paid for the hours they deliver.

Rule 3

Faces and IP blurred

Bystanders, screens, drawings and part numbers are masked before delivery.

Rule 4

Shop owner sign-off

We record only where the owner has approved it in writing.

MD-800 · FAQ

Questions from the break room

Q-01Who does the recording?

Working tradespeople: welders, machinists, press operators, assemblers and mechanics. They record jobs they already do, with our kit, after training and signing consent.

Q-02Can you record a task that is not in the catalog?

Yes. The catalog is where we start. Send the task and we will tell you how fast we can staff it.

Q-03How do you check quality?

Every session is reviewed against the spec: framing, hands in view, task completed, signals in sync. Clips that fail are recorded again, not delivered.

Q-04Can we start small?

Most clients start with a pilot on one or two tasks, to test the data in their pipeline before committing to volume.

Q-05Who owns the data?

Rights and exclusivity are set in each contract. Data collected for your project can be delivered for your exclusive use.

Q-06Which labels can you deliver?

Step segmentation, hand pose, tool and part tracking and scene structure are the most common. We follow your schema and output format.
