|
| ### Dataset Summary |
|
|
| **FieldData Outdoor Labor Motion Dataset (FOLMD)** is a multi-modal motion dataset of professional outdoor workers performing real-world manual labor tasks in urban environments in Japan. |
|
|
| This dataset is designed to support the development of **physical AI foundation models** and **embodied robotic systems** targeting outdoor maintenance and construction tasks. All data was collected from professional workers at actual job sites — not from staged laboratory environments. |
|
|
| The v1.0 release covers a complete two-phase urban fence restoration task: |
| 1. **Graffiti removal** using chemical solvent and rag wiping |
| 2. **Repainting** with black paint using brushes at multiple heights and postures |
|
|
| Data modalities include egocentric RGB video, depth maps (Intel RealSense D435i), full-body IMU (8-point, Mbientlab MetaMotionS), glove-based grasp force (Tekscan Grip System), and annotated 3D skeleton sequences (SMPL format). |
|

|
|
| ## Why This Dataset? |
|
|
| | Challenge for Robots | What This Dataset Provides | |
| |---|---| |
| | Vertical surface contact control | Sustained brush pressure on metal slat fence (9–25 N) | |
| | Low-posture precision work | Deep crouch / kneeling brushwork at ground level | |
| | Boundary-aware manipulation | Painting within 10 mm of masking tape edges | |
| | Multi-posture task transitions | Standing → crouching → kneeling within a single session | |
| | Visual quality assessment | Workers pausing to inspect coverage, detecting missed spots | |
| | Multi-agent coordination | 3–4 workers dividing fence height and working in parallel | |
|
|
| These tasks involve sustained contact with irregular vertical surfaces, fine motor control under physical load, and situated decision-making — all critical challenges for next-generation manipulation models. |
|
|

|
|
| ## Supported Tasks |

|
| ## Dataset Creation |
|
|
| ### Motivation |
|
|
| Physical AI and embodied robot models are rapidly advancing, but publicly available training data for **outdoor real-world manipulation tasks** remains extremely scarce. Existing motion datasets focus primarily on laboratory manipulation, household tasks, or driving — leaving a large gap in construction, maintenance, and urban service work. |
|
|
| This dataset addresses that gap by collecting data from professional Japanese workers performing skilled outdoor maintenance tasks. Japan's workforce is recognized globally for precision, safety discipline, and consistent execution — making it an ideal source of high-quality demonstration data. |
|
|
| ### Collection Methodology |
|
|
| - Task protocols defined in cooperation with professional site supervisors |
| - Sessions conducted at real operational job sites |
| - Multiple skill levels included to capture expert vs. novice motion differences |
| - Both "successful" and "recovery from failure" motion captured and labeled |
| - All data cleaned, synchronized, and formatted to be pipeline-ready |
|
|
| ### Known Limitations |
|
|
| - All data collected in Tokyo metropolitan area — urban environment bias |
| - Nighttime and rainy-weather sessions represent < 15% of current dataset |
| - Force glove covers right hand only |
| - Skeleton estimation accuracy degrades at extreme joint angles (> 110°) |
