This dataset was created using [LeRobot](https://github.com/huggingface/lerobot).
## Dataset Description
FMB (Functional Manipulation Benchmark) **insert** primitive, converted to LeRobot v3.0 for pi0.5 (pi05) SFT.
**Single-peg subset**: shape 1 / size M / length S only (75 episodes). The full insert set is at `DAVIAN-Robotics/fmb-insert-4cam`.
## Source and license
Derived from the FMB single-object manipulation dataset (`insert_only_*.npy`), released by the RAIL lab at UC Berkeley under **CC BY 4.0**. This derived dataset carries the same license. If you use it, cite the original work:

## What was kept and what was dropped
Everything in the source `.npy` **except the four depth maps**, which were dropped for size (uint16 256x256 x4 = 512 KB/frame). The original `.npy` files remain the place to go for depth.
- 4 RGB views, remapped to pi05 camera slots: `side_1` -> `base_0_rgb`, `wrist_1` -> `left_wrist_0_rgb`, `wrist_2` -> `right_wrist_0_rgb`, `side_2` -> `side_1_rgb` (the fourth is an extra slot beyond the 3 that `lerobot/pi05_base` was trained on)
- `observation.state` (8) = `tcp_pose` (7) + `gripper` (1), the pi05 convention
- `action` (7) = FMB's own commanded action: **normalized Cartesian delta [-1, 1] x 6 + gripper**. Not an absolute pose — do not apply a delta transform on top of it
- Original fields preserved alongside: `tcp_pose` (7), `tcp_vel` (6), `gripper` (1), `joint_pos` (7), `joint_vel` (7), `tcp_force` (3), `tcp_torque` (3), `jacobian` (42, row-major 6x7), `primitive_id` (1), `object_meta` (6 = shape, size, length, color, angle, distractor)
## Caveats
- **fps = 10 is an assumption.** FMB does not publish its control frequency; 10 Hz was inferred from a sample trajectory (16 cm TCP descent over 60 steps). It affects only LeRobot timestamps and chunk interpretation.
- Episode lengths vary: min 17, median 46, max 128 steps (measured over 120 samples of the full insert set).
- Every episode's `object_info` was cross-checked against its filename during conversion.
