Egocentric Injection Molding Machine Tending Data

It is first-person video of a person tending an injection-molding machine, recorded from a head-mounted camera, with two wrist cameras for a closer view of the hands. The contributor is a paid, consented person following a written skill spec, not an actor and not a robot.

The point of the data is what the hands do across the whole loop: opening the mold press, removing or pulling the parts, checking them, trimming, placing them in part bins and restarting the cycle. It is labeled so each step can be sliced out and trained on separately or as one longer episode. Where the site states nothing, a table says "Not stated" and the answer lives in the spec or the quote.

The task catalog lists two rows for it, both in the Plastic & Light-Assembly Manufacturer environment of the Manufacturing & Workshops sector, whose examples are consumer goods assembly, packaging operations, labeling and quality inspection on a production line. One is "Injection-Molding Machine Tending": "Open the mold press, remove parts with gloves, trim and drop them into bins, restart the cycle." The other is "Tend and unload an injection-molding machine using heat gloves and part bins": "Pull hot parts from the mold with heat gloves, check them and place them in part bins."

Both are Medium, both list a head-mounted phone or multiview rig, and both are Ready to deploy. That is everything the catalog states, so the first table sets the two rows side by side and the rest of this page says "Not stated" wherever a buyer might expect a detail such as a machine model, a mold type, a part or a cycle time.

The first row starts with the press and ends with the cycle. It opens the mold press, removes parts with gloves, trims and drops them into bins, and restarts the cycle. It does not name heat gloves or a check. The second row names two items in its title, heat gloves and part bins, and describes pulling hot parts from the mold, checking them and placing them in part bins. It does not open the press, trim or restart the cycle.

A buyer can ask for either, or for both in one spec. The site does not say how the two overlap in practice, whether the gloves in the first row are the heat gloves of the second, or where one cycle ends and the next begins, so the spec states which stages are wanted and where each begins and ends.

The two rows give a natural cut: open the mold press; remove or pull the parts; check the parts; trim; drop or place the parts into the bins; restart the cycle. A spec that says "tend the machine" gives you one long action segment. A spec that names those stages gives you a sequence you can slice by step.

The step table sets each stage beside the episode field that carries it. The stages are the catalog’s own wording. How finely a spec splits them, and where each one starts and ends, is a spec decision and not a stated default. The catalog does not say how many cycles, or how long a run, make up one episode.

The catalog ties both rows to the Plastic & Light-Assembly Manufacturer environment and lists a head-mounted phone or multiview rig. The wider site describes a head camera plus two wrist cameras, a depth sensor and an IMU, shown in the capture table below.

The site does not state which plants host a given row, what the machines or presses are, how access to a plant is arranged, or how many contributors are available for it. The spec settles location and access, and the quote settles reach.

The catalog marks both rows Medium. It does not say why a row sits at a level, so this page does not explain it beyond what the rows list: opening a press, removing parts with gloves, trimming, checking and placing parts into bins, and restarting a cycle.

Ready to deploy is the catalog’s status for both rows. The catalog does not define it further, so ask what it means for your region and your timeline when you request the quote.

An episode is one contributor performing one task from the skill spec, recorded with ten hardware-synchronized streams that line up within 2 ms. The site documents a canonical episode schema, and every delivery format is a view of it.

Hand pose is stored as 21 joints per hand in metres in the head frame, with a visibility flag for each joint. Contact events record when a hand meets an object. The site does not say whether the mold, a part, a bin or a glove counts as the object, so settle it in the spec.

Action segments carry a start, an end, a verb and a noun from a taxonomy the site states as 97 verbs and 512 nouns, human-reviewed. Every episode links to its contributor’s signed release by a consent artefact ID, and each batch ships with a data card.

The unit of labeling is the action segment: one start, one end, one verb, one noun. Opening the press, pulling the parts, a check, a trim and a drop into a bin can each be one segment if the spec asks for it. Instance masks track object IDs per frame at 848×480, which helps keep parts, bins and the press apart.

Every episode is machine-checked, then reviewed by a human against its skill spec, and rejected episodes are recaptured at our cost. The site states no label for a good or rejected part, cycle count or task success, and no force, torque or tactile reading in standard capture, so ask for any such label at the start.

The site describes a small set of failure modes and what it does about each. Hands hidden from the camera are flagged by a per-joint visibility bit, not guessed, contact events mark when a hand meets an object, and per-frame instance masks keep objects apart. Which parts of the press, the parts or the bins are hidden in this work is Not stated.

Depth ships with a per-pixel confidence map, so a buyer can see where it should not be trusted. The rig is re-solved against a checkerboard at the start and end of every session and accepted only under the 0.28 px RMS reprojection gate. Weak episodes are rejected and recaptured at our cost. The site states no further failure modes for this task, such as lighting, glare, reflections or motion blur, so those are raised in the spec.

Not in standard capture, which is cameras, depth and IMU. A separate glove tier records a tactile signal beside the video, and the tactile glove page describes it. The site does not state that the glove tier is available for these two rows.

If grip pressure on a part matters to your policy, say so in the spec so the glove tier can be scoped and quoted. Do not assume the heat gloves named in the catalog row carry a signal: in the rows they are an item the contributor wears, and the site states nothing about their material or rating.

Only what the site already states applies. Every contributor signs a written release, and each episode links to it. Faces and screens are detected and blurred irreversibly, a human reviewer confirms that no un-consented person is identifiable, and footage with bystanders who cannot be de-identified is discarded rather than shipped.

The site does not state how co-workers on a line or a plant’s own staff are handled beyond that general rule, so settle it in the spec before capture. This is not legal advice, and the executed agreement controls.

The egocentric light assembly manufacturing page covers the whole Plastic & Light-Assembly Manufacturer environment, where the two tending rows are two among many. The egocentric part trimming and deflashing page covers two deflashing rows and lists the tending rows as separate listings, with trimming as one step of a longer cycle.

The egocentric heavy machinery operation page covers one row, working the levers and control panels of presses, cranes or machinery, and lists no injection-molding row. This page takes just the two tending rows and goes deeper on their steps, tools, labels and capture. A buyer who wants a mix can combine rows from several pages in one spec.

The site states one published timeline: from a signed spec to a first validated batch, a median of 48 hours where coverage is already deep, and typically three to four weeks where it is thin because operators have to be staffed. The site does not say which applies to either row and promises nothing faster, so ask when you request the quote.

Collection is on demand, so a focused brief is a normal starting point. One cycle from opening the press to the restart is a reasonable first unit, and a Spec Pilot is a fast way to prove the fill rate and reject rate before you scale.

Data is delivered in RLDS, LeRobot, WebDataset, HDF5, zarr or Rerun .rrd, or as raw streams with metadata, with the episode schema as the canonical layout. QA runs once, against the canonical episode, before any format is cut. The formats table sets the site’s delivery next to each maintainer’s own documentation, linked under Sources.

The license is perpetual, irrevocable and worldwide, buyer-owned and non-exclusive by default, with exclusivity available as a separate term and the executed order form governing.

Firsthand captures humans, not robots. Episodes carry human hand pose and human action labels, so using them for a specific robot means your own retargeting step. The site does not state robot actions, teleoperation data or any claim about a particular model or embodiment for this task.

What the data gives a lab is the human side of the job: the order of steps, how the hands hold and move a part, and where a step begins and ends. A lab can use that for imitation, for segmenting a task into steps or for evaluation. Each of those is the buyer’s own use of the data.

Start with the free sample pack to check the loader and label quality, then move to a Spec Pilot: a small, fast first batch against the written spec that proves the fill rate and reject rate on your conditions before you scale.

A good tending brief names the setting, the items, the stages of the cycle, how each stage starts and ends, what counts as a reject and the privacy rule for the plant. The site’s skill-spec guide walks through that structure. Then request a custom dataset.
