The hard parts are the judgments: whether the plug is seated, how tight is tight enough for a filter, when the flow has slowed enough to move on, and how to read a dipstick in poor light. Technicians work from pits and from lifts, with drain pans, filter wrenches, funnels, and torque wrenches, and they check for leaks before handing the car back.
Head-mounted cameras capture the view under the car and at the filler. Fixed cameras in the bay or pit capture the full body and the vehicle. The feeds are time-synchronized. Recording spans entire shifts at operating quick-lube centers and garages in five countries, with consented and paid participants.
A researcher receives episodes per vehicle, segmented into labeled steps with plain-language descriptions and success or failure tags. Hand, tool, and part tracking are available if needed. The dataset is written to your own storage in your own schema. Footage is cleared for commercial model training.
