Apple Arts Studios Motion Capture Dataset

Dataset Overview

The Apple Arts Studios Motion Capture Dataset is a professionally captured, full-body human-motion dataset designed for:

• Artificial intelligence
• Humanoid robotics
• Motion generation
• Animation
• Simulation
• Action recognition
• Human-motion research

This release contains 5 hours of originally captured motion data.

Left–right mirrored versions of the original motions are also included, increasing the total distributed duration to 10 hours.

Original captured motion: 5 hours
Mirrored motion augmentation: 5 hours
Total distributed motion duration: 10 hours

The mirrored motions are derived from the original recordings and should be treated as data augmentation, not as independently captured performances.

The dataset covers locomotion and full-body movement across:

• Flat rubbered floors
• Ramps
• Stairs
• Object-interaction environments

It includes multiple:

• Movement speeds
• Directions
• Body positions
• Transitions
• Movement styles
• Performer variations

Each motion is provided in the following representations:

• SOMA Uniform BVH at 30 FPS
• Unitree G1 CSV
• JSON metadata
• Original and mirrored variants
• Structured environment, category, action, and actor hierarchy

Motion Representations

1. SOMA Uniform BVH

The SOMA Uniform BVH files contain the same motions converted to the standardized SOMA Uniform skeletal representation.

These files are provided at 30 FPS and use a consistent:

• Skeleton hierarchy
• Joint naming convention
• Bone structure
• Body proportion
• Reference representation

The standardized representation allows motions from different performers to be compared and processed using the same skeletal structure.

The SOMA Uniform representation may support:

• Motion-generation research
• Motion retrieval
• Skeletal representation learning
• Cross-actor motion comparison
• Standardized animation processing
• Human-motion machine learning
• Motion classification
• Motion prediction
• Motion embedding research

2. Unitree G1 CSV

The Unitree G1 CSV files provide motion data mapped to the Unitree G1 humanoid robot representation.

These files are intended for robotics research and may support:

• Human-to-robot motion retargeting
• Humanoid imitation learning
• Motion-policy development
• Simulation demonstrations
• Whole-body control research
• Physical-AI applications
• Reinforcement-learning research
• Robot-motion visualization

Important Safety and Compatibility Notice

The Unitree G1 CSV files should not be treated as immediately deployable robot-control commands.

---

3. JSON Metadata

Each motion is accompanied by structured JSON metadata.

The metadata may include:

• Motion identifier
• Motion name
• Action name
• Category
• Subcategory
• Actor identifier
• Take number
• Version number
• Motion representation
• Frame rate
• Frame count
• Duration
• Original or mirrored status
• Movement direction
• Movement speed
• Object or prop information
• Relative file path
• Capture-system information
• Skeleton information

The metadata connects the corresponding SOMA Uniform BVH, and Unitree G1 CSV representations of the same motion.

---

Frame-Rate Information

The dataset contains representation-specific frame rates.

Representation	Frame Rate
SOMA Uniform BVH	30 FPS
Unitree G1 CSV	Recorded in the corresponding file metadata

Users should not assume that all distributed representations use the same frame rate.

When comparing or synchronizing SOMA Uniform BVH, and Unitree G1 CSV files, users should account for:

• Resampling
• Frame indexing
• Frame count
• Motion duration
• Timestamp alignment
• Start-frame alignment
• Representation-specific processing

The filenames remain consistent across representations so that matching files can be identified and paired automatically.

---

Original and Mirrored Motions

The dataset contains both original and left–right mirrored motion files.

Original Motions

Original motions are captured performances processed through the Apple Arts Studios motion-capture pipeline.

Mirrored Motions

Mirrored motions are derived from the corresponding original motion by applying left–right motion transformation.

Mirrored files are identified in the metadata using the original or mirrored status.

A mirrored motion should remain connected to its original source motion through a corresponding source-motion identifier.

Mirrored motions are included as augmented data and are not counted as separately captured performances.

---

Dataset Organization

The dataset is organized using a structured hierarchy based on:

1. Motion representation
2. Motion environment
3. Original or mirrored status
4. Surface or interaction type
5. Action category
6. Action name
7. Actor identifier
