Engineering data
Physical AI data
Eval environments

Expert data from the factory floor.

We come out of manufacturing. Alex Machine Tools designs and builds surface grinding machines in India, and runs precision job shops doing contract machining on customer parts. That gives us practicing engineers, live production floors, and parts held to real tolerances.

01 What we do

Training data and evaluation environments from a real production floor. Two distinct programs, scoped separately.

Program A

Engineering and design data

Mechanical design and CAD, process planning, machining, inspection, and the judgment calls in between. Produced by engineers who do the work for a living.

Program B

Physical manipulation data

Egocentric and instrumented capture of skilled industrial work as it happens: deburring, fixture loading, gauge inspection, assembly. Video, depth, and hand and wrist pose, with calibrated fingertip force where the task calls for it. Delivered in LeRobot format.

A scoped manipulation program can specify:

Head-mounted Chest-mounted Wrist-mounted UMI handheld gripper RGB-D IMU Hand and wrist pose Six-axis fingertip F/T on request Per-sensor calibration provenance LeRobot format

02 Why us

Skilled people, not a crowdThe data comes from engineers who design production machine tools and operators whose trade is the task. Not gig workers following a script. The skill of the person is the value of the record.

Your specTask family, rig, modality, format, volume. You define it, we produce against it. If it happens on a floor or at a design desk, we can record it.

Checkable workA design either builds or it does not. A part either passes metrology or it does not. Output can be scored against physical ground truth, not a human opinion.

03 How we work

Real floors, skilled handsFive-plus sites spanning grinding machine manufacture, precision job shop work, warehousing, and dispatch. Real parts, real tolerances.

Metrology disciplineOur roots are in precision manufacturing. Daily reference checks, drift tracking, and a QC verdict on every delivered item.

One program at a timeEngineering data and physical AI data are different products with different buyers. Each is scoped, run, and delivered on its own.
