- Copy openarm_bimanual_pybullet.urdf and all referenced STL/DAE meshes
into src/lerobot/robots/openarms/urdf/
- Update openarms_follower.py to prefer the bundled URDF over the
external ~/Documents/openarm_description path
- Includes visual and collision meshes for arm, body, and end-effector
- Force-add .stl and .urdf files past .gitignore
The previous implementation had a double-normalization bug: the
preprocessor normalized actions with absolute stats, then
convert_to_relative subtracted normalized state (wrong), then the
per-timestep normalizer re-normalized.
Now the correct flow is:
1. Convert batch to relative on raw data (before preprocessing)
2. Compute global relative stats (mean/std across all timesteps)
3. Hotswap the preprocessor normalizer to use relative stats
4. Preprocessor normalizes relative values correctly
This brings loss from ~3000+ down to ~0.5, matching the main branch.
Made-with: Cursor
When rename_map maps a dataset key to observation.state, the raw
dataset used for stats computation still has the original key.
Reverse the rename_map to find the correct key.
