| # evButtonPush — 260422-01 (v01) |
|
|
| ## 한국어 |
|
|
| **ROBOTIS OMY** 6-DoF 팔이 **NVIDIA Isaac Sim / Isaac Lab** 환경에서 엘리베이터 호출버튼을 누르는 시뮬레이션 데모셋 (v01). 스크립트된 IK teacher로 자동 수집됨. |
|
|
| > v02 (개선된 contact-force 기반 teacher + 엘베 문 FSM 포함)는 |
| > [`RobotisAI/evButtonPush-260423-01-hdf5`](https://huggingface.co/datasets/RobotisAI/evButtonPush-260423-01-hdf5) |
| > 에서 받을 수 있습니다. |
|
|
| ### Task |
| - Task ID (Isaac Lab): `RobotisLab-CallButton-Right-OMY-v0` |
| - 로봇: ROBOTIS **OMY** (6축 팔 + 2지 그리퍼) |

| ### 카메라 |
| |
| 3대 모두 **RGB, 1920 × 1200, Pinhole**: |
| - 수평 aperture 20.955 mm |
| - 수직 aperture 13.097 mm (16:10 비율로 자동 계산) |
| - clipping (0.01, 100) m |

|
|
| OMY USD 내부의 `world` prim은 시뮬레이션 월드가 아니라 **로봇 base (link0)**를 가리킴. |
|
|
| ``` |
| world_pose(cam_top) = robot.root_pose_w ⊙ offset_cam_top |
| world_pose(cam_wrist) = robot.root_pose_w ⊙ FK(link0→link6) ⊙ offset_cam_wrist |
| ``` |

| ## English |
|
|
| Simulated demonstrations of a **ROBOTIS OMY** 6-DoF arm pressing an elevator |
| call-button, collected in **NVIDIA Isaac Sim / Isaac Lab** with a scripted |
| IK teacher. **This dataset contains the v01 collection only.** |
|
|
| > The improved v02 collection (contact-force teacher with elevator door FSM, |
| > `call_button_lit` observation) lives at |
| > [`RobotisAI/evButtonPush-260423-01-hdf5`](https://huggingface.co/datasets/RobotisAI/evButtonPush-260423-01-hdf5). |
|
|
| ### Task |
|
|
| - Task ID (Isaac Lab): `RobotisLab-CallButton-Right-OMY-v0` |
| - Robot: ROBOTIS **OMY** (6-DoF arm + 2-finger gripper) |
| - Pedestal: 0.908 m, gripper always closed (stiffness 2 × 10⁶, effort 5000) |
| - Elevator USD: random choice from 100 variants (`elevator_setup_new`) |
| - Robot initial pose randomization (per-seed): |
| - standoff distance to button: 0.55 ~ 0.65 m |
| - lateral offset: −0.05 ~ 0.05 m |
| - yaw: 0° |
|
|
| ### v01 properties |
|
|
| - **46 demos**, seeds span `0`–`60` |
| - Older teacher that judged success purely by tip-to-button distance |
| (threshold 0.050 m) — no physical contact check |
| - No `call_button_lit` observation, no elevator door motion. |
| - Use as a baseline / ablation reference. |
|
|
| ### Cameras |
|
|
| All three cameras record **RGB, 1920 × 1200, Pinhole**: |
| - horizontal aperture 20.955 mm |
| - vertical aperture 13.097 mm (derived from 16:10 aspect) |
| - clipping (0.01, 100) m |
|
|
| | Name | Prim path | Frame | Position (m) | Quat (w, x, y, z) | FOV (H / V / D) | focal | |
| |---|---|---|---|---|---|---| |
| | `cam_wrist` | `Robot/OMY/link6/cam_wrist` | link6 (local, moves with arm) | (0.000, −0.080, 0.070) | (0.0018, −0.0018, 0.7071, 0.7071) | 83.21° / 58.06° / 92.64° | 11.8 mm | |
| | `cam_top` | `Robot/OMY/world/cam_top` | robot base | (0.000233, 0.1499, 0.43953) | (0.5144, 0.4146, −0.5064, −0.5542) | 92.67° / 66.44° / 102.03° | 10.0 mm | |
| | `cam_belly` | `Robot/OMY/world/cam_belly` | robot base | (0.08705, 0.1499, 0.1075) | (−0.4901, −0.5097, 0.5097, 0.4901) | 92.67° / 66.44° / 102.03° | 10.0 mm | |
|
|
| The `world` prim inside the OMY USD refers to the robot's base frame (link0), |
| **not** the simulation world. |
|
|
| ``` |
| world_pose(cam_top) = robot.root_pose_w ⊙ offset_cam_top |
| world_pose(cam_wrist) = robot.root_pose_w ⊙ FK(link0→link6) ⊙ offset_cam_wrist |
| ``` |
