# RoboDojo Task Examples Browser

Task-indexed MP4 browser for 43 official task pages, 105 selected demonstrations, and website evaluation demos.
Videos are read directly from the curated HF dataset. This Space contains only static HTML and task metadata, no duplicate video data.

Dataset: https://huggingface.co/datasets/Travor278/RoboDojo-Task-Examples

Deep links use `?task=0` through `?task=34`; eval-only tasks use task keys such as `?task=align_blocks`.
