Embodied AI Data Collection and Engineering

What is embodied AI multimodal data collection and data engineering?

This project service builds the engineering chain for robot learning, policy training, perception and control validation: task definition, acquisition-system development, teleoperation or demonstration, multi-sensor synchronization and calibration, curation, annotation, format conversion and dataset acceptance. A project can start with one robot and representative tasks as a P0 feasibility gate, then scale only after data validity, coverage and downstream usability are reviewed.

What robot data can be collected and engineered?

The robot platform, task and training stack determine the fields. Sampling rates, clocks, precision and acceptance thresholds are confirmed in the project SOW.

Data group	Typical fields	Acceptance focus
Vision and spatial data	RGB, multi-camera, stereo, depth, point clouds, camera intrinsics and extrinsics	Timestamps, frame integrity, exposure quality, calibration residuals and coordinates
Robot state	Joint position, velocity and torque, end-effector pose, gripper state, odometry and IMU	Units, frames, sampling continuity, packet loss and device versions
Interaction and action	Teleoperation commands, action sequences, force/torque, tactile and contact events, task phases	Observation-action alignment, event boundaries, failure and recovery segments
Semantics and metadata	Language instructions, object and scene labels, operator events, environment and version data	Label definitions, permissions, coverage, consistency and traceability

Service modules

Modules can be selected by project stage; the full set is not mandatory.

Scenario and task design: define target behavior, phases, object variation, failures, long-tail conditions and coverage.
Acquisition-system development: integrate cameras, depth, point clouds, IMU, joints, grippers, force sensing and control interfaces.
Teleoperation and demonstration: connect existing devices or develop an agreed operator interface, event markers and safe-stop path.
Multimodal synchronization and calibration: align clocks, frames, triggers and calibration versions, with measured records.
Data governance and annotation: integrity checks, deduplication, anomaly review, privacy processing, task/object/action labels and sampling QA.
Format and platform adaptation: raw data and metadata, ROS bag/MCAP, Parquet/MP4, LeRobot-compatible or customer-defined structures.
Simulation and synthetic data: create difficult-condition scenarios or trajectories and identify them separately from real data.
Training and validation interfaces: loaders, replay and baseline checks; model training and performance targets require a separate scope.

Suitable project types

Industrial manipulation such as grasping, sorting, assembly, loading and tool use.
Warehouse logistics, mobile manipulation, inspection, navigation and human-robot work areas.
Humanoid, wheeled, quadruped, manipulator, gripper or dexterous-hand platforms.
Existing-platform upgrades and international projects requiring on-premises, remote or staged data delivery.

What is needed to start?

Robot, controller, teleoperation device and sensor inventory, interfaces, protocols, firmware, ROS/ROS 2 graph or code baseline.
Task definition, operating sequence, object and scene range, failure conditions, safety areas and variation factors.
Data purpose, target model or framework, format, delivery location, retention period and acceptance owner.
Site permission, operator consent, third-party asset licenses, data rights, privacy and cross-border requirements.

Delivery process

Requirements and data-compliance assessment: confirm platform, task, sensors, purpose, site and rights boundary.
P0 feasibility gate: test interfaces, synchronization, acquisition stability, data structure and downstream loading on representative tasks.
Freeze the SOW and acceptance baseline: fields, format, coverage, sampling, thresholds, batches and change rules.
Collect, curate and deliver in versions: acquisition, cleaning, annotation, checksums and stage reviews.
Downstream validation and loop closure: load, replay or pre-training checks, followed by targeted data or strategy correction.

Possible deliverables

Task specification, data dictionary, coverage matrix, naming and version rules.
Acquisition software, device configuration, interface adaptation, synchronization and calibration material.
Versioned dataset batches, metadata, checksums and raw/derived data relationship notes.
Cleaning, annotation, sampling-QA rules and quality reports.
Converters, loaders, replay scripts or import instructions for the agreed platform.
Test records, known issues, limitations and acceptance checklist.

How is data quality accepted?

There is no context-free universal number. Thresholds must be tied to the device, task, batch, tool version and test method. Typical checks include:

Multi-sensor timing offset, frame/message loss, sampling continuity and calibration records.
Valid episode ratio, success/failure segments, anomaly reasons and task coverage matrix.
Annotation consistency, sampling results, privacy-processing records and data lineage.
Directories, fields, units, coordinate frames, checksums, versions and loader usability.
Import, replay or pre-training read tests in the agreed environment.

Data security and delivery for international projects

If faces, voices, homes or factories, locations, device identifiers or operator information are involved, the lawful source, authorization, purpose, minimum fields, retention, access control and de-identification method must be defined before collection. International projects may use local acquisition, local processing, customer-environment deployment and staged delivery; the parties must confirm the applicable cross-border route.

The contract should distinguish rights and use limits for raw, curated, annotated and synthetic data, acquisition tools, conversion scripts and model outputs, including deletion, return, backup and third-party material handling.

Capability and responsibility boundaries

This is a project-scoped data collection and engineering service. It does not claim an existing large-scale data factory or pre-set data volume, schedule, quality threshold or site capacity. Scale-up requires a separate review of robots, sites, operators, safety and intended use.

Dataset acceptance can cover fields, timing, coverage, loading and replay, but the dataset does not guarantee model accuracy, generalization, convergence, commercial outcomes or regulatory approval. Model metrics require a defined model, task, evaluation set and test conditions.

Engineering formats and public technical references

The following public material can inform data structures and validation. A reference is not a certification, conformity statement or third-party endorsement.

Frequently asked questions

Can data acquisition be added to an existing robot?

The current controller, sensors, clocks, network, compute, ROS/ROS 2 interfaces and safety strategy can be assessed first. Hardware or software changes depend on interface access and test results.

Does Winge provide teleoperation equipment and collection operators?

Winge can integrate customer equipment or evaluate a teleoperation link, operator UI, collection station and training. Procurement, on-site staffing, safety, travel and scale must be listed separately in the SOW.

Can you deliver LeRobot, ROS bag or custom formats?

Raw data and metadata can be delivered and converted to ROS bag/MCAP, Parquet/MP4, a LeRobot-compatible structure or a customer format by written agreement. Fields, versions, encoding, compression, directories and loader tests are confirmed during P0.

Which metrics determine data quality?

Typical checks cover timing offset, frame or message loss, valid segments, task coverage, calibration, annotation consistency, privacy processing, checksums, loading and replay. Project-specific thresholds are agreed in writing.

Does completing data collection guarantee model improvement?

No. Model architecture, training method, distribution, task definition, evaluation set and deployment environment also affect results. A baseline model and evaluation loop can be scoped separately.
