Dataset Viewer
The dataset could not be loaded because the splits use different data file formats, which is not supported. Read more about the splits configuration. Click for more details.
Couldn't infer the same data file format for all splits. Got {NamedSplit('train'): ('parquet', {}), NamedSplit('test'): ('json', {})}
Error code: FileFormatMismatchBetweenSplitsError

Per-frame features
| Feature | dtype | shape | Meaning |
|---|---|---|---|
action |
float32 | [6] |
Commanded targets — 17-D on XLeRobot (left/right arm ×6, head ×2, base x/y/theta vel); 6-D on SO-101 (shoulder_pan, shoulder_lift, elbow_flex, wrist_flex, wrist_roll, gripper). |
observation.state |
float32 | [117] |
RAW telemetry — 84-D on XLeRobot (17 motors × {pos, current_raw, load_raw, vel_hw} + base x/y/theta vel + 13 GY-91 IMU channels; imu.mag_* is NaN, an MPU6500 has no magnetometer). 117-D on SO-101/sim, which additionally bakes in the EKF breakdown (estimated/tau_ext, model/tau_*, tcp/wrench/, hpi/gripper/). |
observation.sim_model_force |
float32 | [36] |
Ground truth, sim only (36-D): per-joint model decomposition (tau_motor, tau_gravity, tau_coriolis, tau_inertial, tau_friction, tau_model). |
observation.sim_contact_force |
float32 | [24] |
Ground truth, sim only (24-D): per-joint true external torque (tau_ext, tau_ext_residual, tau_ext_jac, tau_ext_contact) — the label an estimator is graded against. |
observation.sim_tcp_wrench |
float32 | [12] |
Ground truth, sim only (12-D): true TCP wrench, contact and F/T-sensor variants. |
observation.sim_pose |
float32 | [7] |
Ground truth, sim only (7-D): cup position + quaternion. |
observation.sim_task |
float32 | [2] |
Ground truth, sim only (2-D): task success / failure flags. |
observation.hpi |
float32 | [9] |
Force channel (9-D): [grip tau_ext, grip q, grip dq, TCP wrench fx fy fz tx ty tz] — input to the force-aware (A1) models. NOT present on XLeRobot platform data: estimation there is a deliberate offline step so the estimator stays an experimental axis. |
observation.images.top |
video | [480, 640, 3] |
Head / overview camera (RGB). |
observation.images.top_depth |
image | [480, 640, 1] |
Overview depth (int16, 1-channel). Not used by ACT; dropped when building training variants. |
observation.images.head |
video | [480, 640, 3] |
Head / overview camera (RGB). |
observation.images.head_depth |
image | [480, 640, 1] |
Overview depth (int16, 1-channel). Not used by ACT; dropped when building training variants. |
