• —observation.images.head_camera: video [3, 480, 640]

Policy-Facing Columns

• —observation.state: normalized robot joints in [0, 1]
• —observation.drawer_index: selected drawer target for each frame
• —action: normalized next-step robot joint targets in [0, 1]
• —observation.images.head_camera: RGB video frames from the robot camera

Extra Columns

• —observation.state_raw: raw MuJoCo joint positions
• —action_raw: raw next-step MuJoCo joint positions
• —episode.drawer_index: selected drawer index for each frame
• —episode.cube_position: initial cube position for each frame
• —episode.cube_quaternion: initial cube orientation for each frame

Notes

The dataset was produced by first computing the full IK episode, then resampling the robot joint trajectory at a constant normalized joint speed before saving frames/actions. Training code appends the normalized drawer target (drawer_index - 1) / 8 to the policy state when observation.drawer_index is present.

Joint limits and the normalization formula are stored in meta/info.json.
