Route Red-Yellow Vector Split-Subtask Example

This is a LeRobot v2.1 example derived from ajaysri/route_red_yellow_vector_subtasks_pi05. Source episode(s) 2 are split into one output episode per maximal contiguous run of metadata.route.active_subgoal.

The example has 4 output episodes and 948 frames. All three videos are cut on the same frame boundaries as the Parquet data and re-encoded as H.264 at 100 Hz.

Why the split count is inferred

The complete 212-episode source dataset contains suffixes of the four-phase route task:

• four segments: 52 episodes
• three segments: 51 episodes
• two segments: 53 episodes
• one segment: 56 episodes

No repeated or backward transitions were found. The builder therefore detects boundaries from the frame labels instead of assuming four subtasks.

Provenance

Every frame includes:

• metadata.split.source_episode_index
• metadata.split.source_frame_index
• metadata.split.source_start_frame
• metadata.split.source_end_frame_exclusive
• metadata.split.segment_ordinal

The original visual conditioning, prompts, actions, states, and route metadata are retained. frame_index, episode_index, index, and timestamp are reindexed for the split dataset.
