ARMBench - Stow Success Prediction
This repository is the official Amazon redistribution, on the Hugging Face Hub, of the Stow Success
Prediction subset of ARMBench. The archive under archive/ is Amazon's original release object,
byte-for-byte: a single ZIP64 archive holding 290,608 JPEG images and one Parquet feature table.

Note on the project website.
http://armbench.comis Amazon's canonical home for ARMBench. At the time of writing thehttps://www.armbench.comcertificate has expired, so some browsers will warn before showing the site. This has been reported to the ARMBench team. The arXiv link above is a non-expiring alternative reference.
Note on the paper. This subset comes from the Vulcan Stow program and is cited with
hudson2025stow(arXiv:2505.04572), not with the Sparrow ARMBench paper (arXiv:2303.16382). See Citation.
Dataset Description
The following description is quoted verbatim from Amazon's ARMBench website.
What is ARMBench?
ARMBench is a large-scale benchmark dataset for perception and manipulation challenges across Amazon Robotics systems. The datasets are collected in Amazon warehouses and capture a wide variety of objects and configurations. They comprise images, videos, and tabular data for different stages of robotic manipulation with high-quality annotations.
ARMBench includes datasets from two Amazon Robotics programs. This subset belongs to the Vulcan Stow group, described on the site as:
Vulcan Stow - Amazon's first robot with a sense of touch, built on advances in robotics, engineering, and physical AI. Vulcan can manipulate objects within fabric-covered pods that are divided into compartments, each holding up to 10 items. Using specialized end-of-arm tooling and force feedback sensors, Vulcan can detect when it makes contact with objects and apply appropriate force, making stowing operations more efficient and safer while achieving human levels of packing density and speed.
The site's one-line summary of this task, from the home page, verbatim:
Stow Success Prediction: Complete dataset of 72,000+ stow cycles with bin images, item images, and tabular data. Predict binary outcomes (success/failure) and space creation in fabric-covered pods.
The task, verbatim from the Stow Success Prediction page
The Stow Success Prediction task focuses on predicting the binary outcome (success or failure) of a stow attempt in Amazon Vulcan Stow workcells. In the robotic manipulation context, this task is critical for optimizing warehouse operations and improving the efficiency of robotic stowing systems.
The Stow Success Prediction dataset contains 72,000+ complete stow cycles with data collected from Amazon Vulcan Stow workcells located in an Amazon warehouse. The dataset supports the Success Prediction task: Predicting the binary outcome of a stow attempt (success or failure) based on the provided images and tabular data. The dataset is organized as follows:
Images: All images are named after their corresponding run_id for cross-referencing:
- Induct: Items on the conveyor before stowing
- Pre-stow Pedestal: Bin before stowing
- Mid-stow Pedestal: Bin during the stow process
- Post-stow Pedestal: Bin after stowing
The pedestal images are captured from fixed cameras, showing the specific bin being stowed into at different stages of the stow process.
Tabular Data: A comprehensive table with run_id as the primary identifier and all other feature columns as described below.
Editorial note on the quotations above, so the differences from the live page are auditable and not mistaken for transcription errors: bold and list markup were applied to the page's own headings and bullets, and the four image stages were rendered as a list because the page renders them as one. No word was changed, added, reordered or removed.
One point of interpretation, clearly marked as not Amazon's words. The home-page blurb names two
prediction targets, "binary outcomes (success/failure) and space creation", but the task page defines
only the binary one. The archive ships no separate space-creation label; the columns the site groups
under Space Metrics (mlo, dlo, dao, dco, dloSweep) are the natural regression targets for
that second task. That mapping is this card's reading, not a statement published by Amazon.
Dataset Structure

archive/success_prediction.zip |
40,166,726,870 | Amazon's original release archive, unmodified |
Apart from this card (README.md), that is the whole repository. 40,166,726,870 bytes is
37.408 GiB.
Amazon publishes no checksum sidecar for this subset - unlike the Sparrow defect archives, there is no
.sha256 file next to the release object, and no -tiny sample archive exists for Stow Success
Prediction. See Verifying what you downloaded for what can be checked
instead.
There is no dataset viewer for this repository, deliberately. The Parquet feature table lives inside
the ZIP, and a configs: block pointing at a path inside an archive does not resolve - it would break the
viewer rather than populate it. The recipe below pulls the table out without downloading all 37.4 GiB.

1 | 106,432,610 | 101.502 MiB | - | - | - | - |
The archive is 6,630,421 bytes larger than the sum of its uncompressed members (40,166,726,870 vs 40,160,096,449). That is expected: deflate gains essentially nothing on already-encoded JPEG, while the container adds 290,615 local file headers and a 34.127 MiB central directory. Do not read the ZIP as a compressed archive - read it as a seekable container.
Image resolutions, from a single sampled cycle (run_66e2d40aea, one image per stage) and therefore
not asserted for the whole release: induct 1224x1024, and all three pedestal stages 521x273. The
per-stage min/max byte spreads above (pedestal images range from 1,991 to ~300,000 bytes) make it likely
that resolution or content varies across cycles; Amazon's site does not publish image dimensions, and no
dimension survey was run over all 290,608 files.
The run_id join, verified
The site says the images are "named after their corresponding run_id for cross-referencing". That holds
exactly, and it was checked rather than assumed. Over the full central directory and the full Parquet
table:
run_idin the Parquet table: 72,652 rows, 72,652 distinct, zero nulls.- Each of the four image stages contains exactly 72,652 files, and each stage's set of filename stems
is equal to the Parquet's
run_idset - not a subset, not a superset, for all four stages. - Therefore the set of
run_ids with all four images present is all 72,652 of them.
So one stow cycle is exactly one Parquet row plus exactly four JPEGs, with no orphans in either direction.
The tabular table
| Rows (stow cycles) | 72,652 |
| Top-level fields | 236 |
| Physical leaf columns | 240 |
| Row groups | 1 |
created_by |
parquet-cpp-arrow version 20.0.0 |
| Size inside the ZIP | 95,166,029 bytes deflated / 106,432,610 bytes uncompressed |
The 236-versus-240 gap is not a discrepancy: four fields are nested (...etiquetteViolations
list<string>, ...pBinToProfileBottom and ...pBinToProfileTop list<struct<x,y,z>>,
...binHSweepWaypoints list<null>), and Parquet counts their leaves, so 236 - 4 + 8 = 240.
The single row group means the table is read in one pass; it cannot be streamed by row group.
The release ships no official train/test split. There is no split column, no train.csv/test.csv,
and the website publishes no split for this task. Any split is yours to define - say so in your paper, and
prefer a split that does not leak, since consecutive cycles can share a bin.

How those names map onto the Parquet file
The Parquet column names are not the bare names in the table above. They are namespaced, and the
feature block appears twice. Nothing is missing except podType. The mapping, measured from the file:
| Site's name | Parquet column(s) |
|---|---|
run_id, computed_success, computed_unproductive, computed_defect |
identical, top level |
Item dimensions, weightKg, all Bin Features except podType, all Stow Strategy Features except the three stowStrategy.*, all Space Metrics |
match_risk_features.<name> and match_risk_features.initial.<name> |
itemPackagePackagingType, itemPackageShape, isFragile, isFoldable, containsLiquidClassification, bindingText |
semantic_summary.skumasterAttr.<name> |
stowStrategy.type, stowStrategy.direction, stowStrategy.slotEdgeType |
match_output.stowStrategy.<name> |
podType |
not present in the Parquet file |
The two feature snapshots are the single most important structural fact for anyone training on this table:
match_risk_features.initial.*- 64 fieldsmatch_risk_features.*(non-initial) - 64 fields, the same 64 names
The site does not document the difference between them. Treat them as two snapshots of the same feature vector and do not feed both into a model without checking which one is causally available before the stow decision, or you risk leaking outcome information.
Field counts by namespace, measured: match_risk_features.initial.* 64, match_risk_features.* 64,
semantic_summary.* 20, match_output.* 84, plus run_id and the three computed_* outcomes = 236.
The site documents 42 features; the file carries 236 top-level fields. The ~194 undocumented ones include
full 6-DoF blade and item insert poses (match_output.stowStrategy.binHBladeInsert.*,
...binHItemInsert.*, ...worldHBin.* as translation + quaternion), predicted slot corner coordinates,
band-manipulation waypoints, item-in-hand overhang offsets in cm, insertion costs, the additional space
metrics mao/mco/tao/tco/tlo/dloFlip/dloL2/dloStack, and ten
semantic_summary.operatorAnnotation.* fields whose names indicate human operator entries
(isStowedItemDamage, isPodDamage, bandsNotClosed, etiquetteViolations, ...). Amazon's website
does not document any of these, and this card does not guess at their semantics beyond what the names
say.
Label distribution, measured over all 72,652 rows
| Outcome column | True | False | True rate |
|---|---|---|---|
computed_success |
62,433 | 10,219 | 85.935% |
computed_unproductive |
6,551 | 66,101 | 9.017% |
computed_defect |
3,667 | 68,985 | 5.047% |
The headline task is therefore an imbalanced binary problem with a 14.065% failure rate (10,219 of 72,652). Report precision/recall or average precision on the failure class; accuracy is dominated by the majority class. The three outcome columns are independent booleans, not one 3-way label.
Measured value sets for the categorical columns, as published in the file (strings are carried with their enum prefixes intact - strip them if you want readable labels):
| Parquet column | Distinct | Values and counts |

Known data quirks
Measured properties of this release, documented so you do not have to rediscover them.
isEdgeis a string, not a bool. The values are the characters'0'and'1'. The site's schema calls it bool. Cast explicitly.numItems,numStows,numSuccessfulStows,numberFlat,numberInstances,stowPreviousare strings, not ints. The site's schema calls the first three int.numItemshas 35 distinct string values. Cast explicitly, and decide what to do with any non-numeric value before you do.podTypedoes not exist in the file. The site documents it; a case-insensitive search forpodover all 236 field names returns onlysemantic_summary.operatorAnnotation.isPodDamage.- Strategy-specific blocks are null exactly where the strategy does not apply, and the counts close
perfectly.
match_output.stowStrategy.slotWedge.*is null in 16,710 rows, and 72,652 - 16,710 = 55,942 = theSLOT_WEDGEcount....binSweep.*is null in 56,964 rows, and 72,652 - 56,964 = 15,688 = theBIN_SWEEPcount. These nulls are structural, not missing data. - Exactly one row has a missing semantic summary. All 20
semantic_summary.*fields have a null count of exactly 1 - the same row. No other field outside the strategy blocks in quirk 4 has any null. - Categorical strings carry their enum prefix, and some carry an empty suffix:
ItemPackagePackagingType_(13,369 rows) andItemPackageShape_(23,118 rows) are "present but unspecified", distinct from both null and fromNONE_ITEM_PACKAGE_TYPE. Three states, not two. - The feature vector is duplicated under
match_risk_features.*andmatch_risk_features.initial.*. See the leakage warning above. - The directory names are not the site's stage names.
primary_pedestal_pre/_mid/_postare the site's "Pre-stow / Mid-stow / Post-stow Pedestal". Theprimary_prefix suggests a non-primary camera exists in the source system; none is in this release.
Published figures versus measured figures
Amazon's published figures are given first; figures measured from this exact release follow, labelled as such. Both are reported rather than silently reconciled.
| Quantity | Amazon's published figure | Measured from this release |
|---|---|---|
| Stow cycles | 72,000+ (home page and task page) | 72,652 (Parquet rows, distinct run_ids, and files per image stage - all three agree) |
| Images | not published as a count | 290,608 JPEGs = 4 x 72,652 |
| Download size | not published for this subset | 40,166,726,870 bytes = 37.408 GiB |
| Documented tabular features | 42 (including run_id) |
41 of 42 present; podType absent; 236 top-level fields in total |
numItems, numStows, numSuccessfulStows |
int | string |
isEdge |
bool | string '0'/'1' |
| Column names | bare, e.g. itemLengthPerception |
namespaced, e.g. match_risk_features.itemLengthPerception, with a .initial. twin |
| Image stage names | Induct / Pre-stow / Mid-stow / Post-stow Pedestal | image/induct/, image/primary_pedestal_pre/, _mid/, _post/ |
The 72,000+ versus 72,652 relationship is consistent - "72,000+" is a rounded-down published figure, not a conflicting measurement. The type and naming rows above are genuine divergences between the published schema and the shipped file; the file is authoritative for what you will load, and the site is authoritative for what each feature means.
Verifying what you downloaded
Amazon publishes no SHA-256 for this subset, so there is no official checksum to check against. What can be verified:
hf download amazon/armbench-stow-success-prediction \
archive/success_prediction.zip \
--repo-type dataset --local-dir ./armbench-stow
# 1. exact size
stat -c %s ./armbench-stow/archive/success_prediction.zip # 40166726870

For provenance: the source S3 object's ETag is 050900df7ed32ddff192a71cf2d4bbc5-767. The -767 suffix
means it is a 767-part multipart ETag, not an MD5 of the file, so it cannot be reproduced with
md5sum. It is quoted only so the release object can be matched against the source bucket.
Getting the feature table without downloading 37.4 GiB
With the whole archive in hand:
unzip -p success_prediction.zip tabular/tabular_data.parquet > tabular_data.parquet
python -c "import pyarrow.parquet as pq; t=pq.read_table('tabular_data.parquet'); print(t.num_rows, len(t.schema))"
# 72652 236
A ZIP is a seekable container, so a Range-capable HTTP client can fetch only the table. The byte offsets below were measured from this exact archive and are stable for it:
Local file header of tabular/tabular_data.parquet |
offset 40,035,775,874 |
| Deflated member length | 95,166,029 bytes |
| Uncompressed length | 106,432,610 bytes |
| Compression | deflate (method 8), raw stream, zlib.decompress(blob, -15) |
Fetch bytes=40035775874-40131000000, skip the 30-byte local header plus its name and extra fields, then
inflate. The same two-step trick reads the central directory first: the ZIP64 end-of-central-directory
record is in the last 1 KiB, and the central directory itself is 35,784,783 bytes at offset
40,130,941,989. This was the method used to measure every figure in this card, and it transfers about
131 MB instead of 37.4 GiB. The offsets are a property of the archive, not of the Hub; whether a given
client honours Range requests against a Hub resolve URL has not been tested here.
Dataset Creation
The data was collected from Amazon Vulcan Stow workcells in an Amazon warehouse, as stated on the task page and quoted above: "72,000+ complete stow cycles with data collected from Amazon Vulcan Stow workcells located in an Amazon warehouse."
The outcome columns are named computed_*, which indicates they were derived by the production system
rather than hand-labelled; the semantic_summary.operatorAnnotation.* fields indicate human operator
entries. Amazon's website does not publish the annotation protocol, the definition used to compute
success, unproductive or defect, the annotator population, or inter-annotator agreement, and this
redistribution does not add them. If the precise definition of computed_success matters to your result,
treat it as unpublished and say so.
The source S3 object is dated 2025-07-23, consistent with the August 2025 release entry below.
Release history, verbatim from the ARMBench website
June, 2026: New benchmark dataset released for Blade Insertion Affordance Prediction, with ~29,000 cycles of RGBD images and 3D motion trajectories.
August, 2025: New benchmark dataset released for Stow Success Prediction, adding a fourth key challenge to ARMBench.
Considerations for Using the Data
Intended use. Research and benchmarking of stow outcome prediction - predicting, from bin and item images plus tabular features, whether a robotic stow attempt into a fabric-covered pod will succeed.
Class imbalance. 14.065% of cycles are failures. Report per-class precision/recall or average precision on the failure class.
No official split. Results on this dataset are only comparable if the split is stated. There is none in the release, so publish yours.
Leakage risks, two of them. First, the duplicated match_risk_features.* /
match_risk_features.initial.* blocks: the site does not say which snapshot is taken before the stow
decision, so using both without checking may leak. Second, the images: primary_pedestal_mid and
primary_pedestal_post are captured during and after the stow, so a model that sees them is not
solving the prediction problem the task page describes - it is observing the outcome. A genuine success
predictor has access to induct and primary_pedestal_pre only. The site does not state this
restriction; it follows from its own stage definitions, quoted above.
Scope limits. The data comes from Vulcan Stow workcells in one Amazon warehouse, under that facility's lighting, camera placement, pod geometry and inventory mix. Models trained here should not be assumed to transfer to other workcells, pod types or inventory distributions without re-evaluation.
Personal and sensitive information. The images show items on a conveyor and inside fabric pods. Amazon's website does not publish a de-identification statement for this subset, and this redistribution does not add one.

The ARMBench suite on the Hub
ARMBench is distributed as six downloads, each published as its own dataset under the
amazon organization so you can take only the subset you need. Every
one carries the armbench tag, so
datasets?other=armbench lists the whole family, and
they are grouped in the ARMBench collection on the organization page.

The only change from the site's text is the removal of trailing whitespace at the end of the wrapped author lines. No author was added, removed, reordered, abbreviated or replaced by "and others"; dropping an author would be an attribution failure under CC BY 4.0. The 37 authors, in order, are: Nicolas Hudson, Josh Hooks, Rahul Warrier, Curt Salisbury, Ross Hartley, Kislay Kumar, Bhavana Chandrashekhar, Paul Birkmeyer, Bosch Tang, Matt Frost, Shantanu Thakar, Tony Piaskowy, Petter Nilsson, Josh Petersen, Neel Doshi, Alan Slatter, Ankit Bhatia, Cassie Meeker, Yuechuan Xue, Dylan Cox, Alex Kyriazis, Bai Lou, Nadeem Hasan, Asif Rana, Nikhil Chacko, Ruinian Xu, Siamak Faal, Esi Seraj, Mudit Agrawal, Kevin Jamieson, Alessio Bisagni, Valerie Samzun, Christine Fuller, Alex Keklak, Alex Frenkel, Lillian Ratliff, Aaron Parness.
