HBotChallenge

Training data for the H-Bot challenge: a Panda DROID arm (Franka + Robotiq 2F-85) in Isaac Sim, six tasks. One top-level folder per dataset, named HBot_SixTask_<Seen|Unseen>_<episodes>_<NoSubtask|Subtask>_<source or date>, where Seen / Unseen says whether the objects come from the released seen asset split.

Folder	Episodes	What it is
`HBot_SixTask_Seen_600_NoSubtask_Official/`	600	Unmodified copy of the official release (see below)

HBot_SixTask_Seen_600_NoSubtask_Official

A copy of HorizonRobotics/InstructMove-Dataset, revision h-bot, commit 44e8964b83fbcf7575f66dddbfc36c3a8d06ec06, path horizon_isaac/. It has 100 episodes per task (pick_color, spatial_pick, place_a2b, stack_cubes, open_drawer, joint_direction). SOURCE.json records where and when it was downloaded. The source repository states no license; its own terms apply to this folder, not this repo's license.

horizon_isaac/lmdb/: 134,183 frames. Full-resolution RGB and depth from two external cameras and the wrist camera, plus index and meta. Read by HoloBrain's HorizonManipulationLmdbDataset.
horizon_isaac/lerobot/: LeRobot v2.1 as six ZIP archives. 30 FPS, three 640x360 h264 videos, no depth.

Large files

HF limits a single file to 50 GB. LMDB data.mdb files over 40 GiB are therefore stored as 20 GiB pieces, data.mdb.part-00, data.mdb.part-01, and so on. Each dataset folder's SHA256SUMS lists the whole files that were split.

To download a dataset and rebuild its split files:

hf download QiXiong-SkyXZ/HBotChallenge --repo-type dataset \
    --include 'HBot_SixTask_Seen_600_NoSubtask_Official/*' --local-dir .
cd HBot_SixTask_Seen_600_NoSubtask_Official
find . -name 'data.mdb.part-00' -execdir sh -c 'cat data.mdb.part-* > data.mdb && rm data.mdb.part-*' \;
sha256sum -c SHA256SUMS
