Placement Yellow-Dot Red-Arrow Sanity Dataset

This is a LeRobot-format one-episode sanity export derived from local HDF5 placement data. It uses source recording episode_00201.hdf5, one of the five episodes newer than the existing 197-episode placement export.

Dataset size:

• episodes: 1
• frames: 259
• videos: 3
• export fps: 100
• frame stride from 100 Hz source: 1
• source episode index: 201

Source goal label:

• full-resolution target: (564.0, 223.0) px
• 224x224 overlay target: (98.7, 81.025) px
• image-space orientation: 0.42662749 radians

Instruction:

move the connector to the yellow dot and match the red arrow orientation

The overhead video is rendered from the raw HDF5 overhead camera frame with an anti-aliased red arrow and yellow source dot plotted from HDF5 metadata:

• placement/episode_target_image_xy_px
• placement/episode_target_theta_rad

No green-pixel detection is used. The 1280x800 source image is mapped to a 224x140 view with 42 px vertical padding inside the 224x224 LeRobot video frame.

Timing:

• metadata.source_fps stores the source recording rate from HDF5, normally 100 Hz.
• metadata.export_fps and top-level fps store this dataset's export rate.
• metadata.frame_stride stores the source-frame stride used for export.
• source.action_time_s stores the original source time for the retained frame.
• timestamp stores the LeRobot export timestamp.
