+ # Rhoyn Robotics G1 Teleoperation Sample
23
+
24
+ A sample of whole-body teleoperation data collected on a Unitree G1 humanoid (29 DoF, Dex1 grippers), recorded at 30 Hz. Each folder is a self-contained [LeRobot v3.0](https://github.com/huggingface/lerobot) dataset holding one episode, plus extra sensor streams (depth, lidar, IMU, raw teleop packets) stored alongside it.
25
+
26
+ | Folder | Task | Duration | Frames | Preview |
27
+ |---|---|---|---|---|
28
+ | `wipes/` | Pull a wet wipe from the pack and wipe the table | 97 s | 2,921 | [`previews/wipes.mp4`](previews/wipes.mp4) |
29
+ | `socks/` | Pick up the two socks and pair them together | 92 s | 2,747 | [`previews/socks.mp4`](previews/socks.mp4) |
30
+ | `eggs/` | Crack eggs into the pan and scramble them | 232 s | 6,965 | — |
31
+
32
+ The preview videos tile every camera stream, the IR and depth views, and the lidar point cloud into a single view.
33
+
34
+ ## Loading
35
+
36
+ Each task folder is its own LeRobot dataset, so download the repo and point LeRobot at one folder:
37
+
38
+ ```python
39
+ from huggingface_hub import snapshot_download
40
+ from lerobot.datasets.lerobot_dataset import LeRobotDataset
41
+
42
+ path = snapshot_download("rhoyn-robotics/data-sample", repo_type="dataset")
43
+ ds = LeRobotDataset("rhoyn-robotics/data-sample", root=f"{path}/wipes")
44
+ ```
45
+
46
+ The per-frame data can also be read directly with pandas or pyarrow from `<task>/data/chunk-000/*.parquet`.
47
+
48
+ ## Contents of each episode folder
49
+

68
+ | `observation.images.d405_left`, `d405_right` | 424×240 | Wrist RealSense D405, color |
69
+ | `observation.images.d405_{left,right}_ir1`, `_ir2` | 424×240 | Wrist D405, stereo IR |
70
+
71
+ ### Per-frame data (`data/`)
72
+
73
+ | Key | Dim | Description |
74
+ |---|---|---|
75
+ | `observation.state` | 60 | 29 joint positions, 29 joint velocities, 2 gripper apertures |
76
+ | `observation.effort` | 31 | Measured joint torques |
77
+ | `observation.motor_temp` | 29 | Motor temperatures |
78
+ | `observation.imu.pelvis`, `observation.imu.chest` | 10 each | Quaternion, gyro, accelerometer |
79
+ | `action` | 31 | 29 joint position targets, 2 gripper aperture targets |
80
+ | `action.kp`, `action.kd`, `action.tau_ff`, `action.dq_target` | 29 each | Low-level PD gains, feedforward torque, velocity targets |
81
+ | `action.tau_requested`, `action.torque_cap`, `action.tau_commanded` | 31 each | Torque pipeline: requested, capped, commanded |
82
+ | `observation.torque_budget`, `action.torque_allowed`, `action.torque_limited` | 16 each | Arm torque-safety limiter state |
83
+ | `action.teleop` | 26 | Operator VR wrist poses, locomotion commands (vx, vy, yaw rate, height), triggers, grips, sticks |
84
+ | `action.teleop.buttons` | 8 | VR controller buttons |
85
+ | `observation.teleop_active` | 1 | Whether teleop was engaged |
86
+ | `observation.frame_counter`, `sensor_ts_us`, `frame_offset_us` | 12 each | Per-stream camera sync info |
87
+ | `observation.row_time_us`, `observation.control_offset_us` | 1 each | Row and control-loop timing |
88
+
89
+ Full joint names for every vector are in `meta/info.json`.
90
+
91
+ **Note on NaNs:** `observation.frame_counter`, `observation.sensor_ts_us` and `observation.frame_offset_us` contain NaN in their three depth columns (`d435_depth`, `d405_left_depth`, `d405_right_depth`). This is expected: depth is recorded at 15 fps in `depth/`, and `meta/depth.json` maps each depth frame to its data row.
