# SO-101 Early Collection (superseded)
The project's **first, miscellaneous recordings**, made before the team settled on four
fixed tasks, a consistent recording protocol, and systematic prompt variation.
> [!WARNING]
> **This dataset is superseded and not recommended for training.** It is retained for
> provenance and to document the project's history. The only model trained on it —
> [SmolVLA V1 Misc](https://huggingface.co/Project-IRA/TPSoSe2026_SmolVLA_LeRobot_SO101_Finetuning_V1_Misc_Dataset) —
> does not work.
Part of **[Project-IRA](https://huggingface.co/Project-IRA)** — Interactive Robotic Arm.

## Why it was superseded
The early recordings mixed several exploratory task ideas that were later dropped —
including putting a ball on a plate, putting a box on a marked X, waving, and placing a
chess piece on a Rubik's cube. Episode counts per task were small and inconsistent, and
prompts were not varied systematically.
Fine-tuning on this data produced a model that was useless at essentially everything.
That negative result is what motivated the structured protocol used for every later
dataset: four fixed tasks, exactly 10 episodes per prompt, deliberate prompt variation
every 10 episodes, and documented object-placement schemes.
## Robot setup
| | |
|---|---|
| Robot | SO-101 follower arm (6-DOF), `robot_type: so_follower` |
| Teleoperation | SO-101 leader arm |
| Control frequency | 30 fps |
| State / action space | 6-dim: `shoulder_pan.pos`, `shoulder_lift.pos`, `elbow_flex.pos`, `wrist_flex.pos`, `wrist_roll.pos`, `gripper.pos` |
| Camera `observation.images.desk_view` | 800x600, h264 (recording) |
| Camera `observation.images.wrist_left` | 640x480, h264 (recording) |
> **Inference note:** both cameras are run at **640x480 during inference**, not at their
> recording resolutions, to reduce the payload sent to the inference server.
