LongHorizon — LoHRbench CuRobo Demonstrations (joint-pose)
Success-only demonstration trajectories for 8 long-horizon manipulation tasks from LoHRbench (ManiSkill3, Franka Panda), collected with the CuRobo GPU motion planner.
Two representations of the same success trajectories are provided:
| Path | Format | Episodes | Notes |
|---|---|---|---|
data/, meta/ |
LeRobot v2 | 1,200 (capped 150/task) | training-ready (pi0 / LeRobot pipelines) |
hdf5_joint_pose/ |
ManiSkill HDF5 | 1,383 (all successes) | raw trajectories + filtered metadata JSON |
Both are joint-pose (8D pd_joint_pos) and success-only. The HDF5 set keeps every
successful episode (no 150/task cap), so a few tasks have more than the LeRobot set.
Contents
- Episodes: 1,200 (150 per task × 8 tasks), all successful
- Frames: 3,311,118 @ 20 fps
- Robot: Franka Panda (
panda_wristcam) - Planner: CuRobo (GPU MotionGen)
- Action space: 8D
pd_joint_pos— 7 arm joint targets + 1 gripper command (absolute)

HDF5 success counts (hdf5_joint_pose/)
| task | success episodes |
|---|---|
| stack_10_cube | 150 |
| reverse_stack | 172 |
| stack_active_exploration | 300 |
| pick_active_exploration | 150 |
| fruit_placement | 150 |
| repackage | 150 |
| cluttered_packing | 161 |
| stack_cube_clutter | 150 |
| total | 1,383 |
Each <name>_success.h5 holds only the successful traj_* groups; the sibling
<name>_success.json is the ManiSkill trajectory metadata trimmed to those episodes.
Episode success is taken from the reconciled per-episode label (episodes[].success),
not the unreliable per-step flag. HDF5 schema: obs/agent/qpos (T,9),
obs/sensor_data/{base,hand}_camera/rgb (T,128,128,3), actions (T-1,8).
Notes
- Only successful episodes are included (per-episode success labels reconciled from the ManiSkill collection metadata; the per-step success flag is not used).
- Actions are absolute joint targets. For pi0/pi0.5-style training, convert the 7 arm joints to deltas relative to the current state and keep the gripper absolute.
- This release contains the joint-pose (
pd_joint_pos) representation only (both LeRobot and HDF5). A delta-EE (pd_ee_delta_pose) variant is not included here.
