| ## Dataset Description |
|
|
|
|
| Real-robot evaluation rollouts recorded on a **Rebot B601** 7-DoF arm, from the LeWAM |
| project. Every episode here is a policy rollout on the physical robot — not a |
| teleoperated demonstration — scored by a human operator immediately after it ran. |
|
|
| - **Task:** **tape stack** (`b601_tape_stack`): the arm stacks the green roll of tape on the white roll of tape. Trained on [`LeWAM/b601_tape_stack`](https://huggingface.co/datasets/LeWAM/b601_tape_stack). |
| - **Policy:** a LeRobot **Diffusion Policy** (`horizon=40`, `n_action_steps=36`, `n_obs_steps=2`, widened to `down_dims=[336, 672, 1344]`), predicting an action chunk only |
| - **Success rate:** **0/30 = 0.0%** |
| - **Episodes:** 30 · **frames:** 21299 · |
| **fps:** 30 · **robot time:** 11.8 min |
| - **Wall-clock:** 47.6 min |
| (median 99s, max 204s per episode) — longer |
| than robot time because inference on this hardware runs slower than real time |
| - **wandb run:** [`h8fy0vpa`](https://wandb.ai/halicki/lewam-testing/runs/h8fy0vpa) |
| (`eval-diffusion_b601_tape_stack`) |
| - **Episode cap:** 5400 steps — an episode that hits it is scored a failure. |
|
|
| ### Observations |
|
|
| Three synchronised camera streams (`observation.images.zed_left`, |
| `observation.images.zed_right` from a ZED Mini, `observation.images.wrist_cam` from a |
| wrist-mounted USB camera) plus `observation.state`. `action` is the 7-DoF joint command |
| the policy emitted. |
|
|
| Note the policies were served **torque-only** state (`observation.state` sliced to |
| `*.torq`); the `observation.state` recorded here is the robot's full state vector, so |
| reproducing what the policy actually saw means applying the same slice. |
|
|
| ### Per-episode scoring |
|
|
| `eval_session.json` holds the operator's label for each episode: |
|
|
| | episode | success | steps | seconds | |
