# Raw recording dictionary

Each `raw/<original-take-name>/` contains unchanged `vectors.h5`, `cam1.mp4`, and `cam2.mp4`.
HDF5 groups contain one float64 dataset per named column. `ur_joint_states/q1..q6` are measured joints (radians); `command/cmd1..cmd6` are commanded joint targets (radians). `gripper/grip_pos` and `grip_cmd` use 0=open, 1=closed. GELLO leader coordinates are not policy observations.
`cam1_frames` and `cam2_frames` map zero-based `frame_idx` to `stamp_s` (ROS header seconds) and `t_rel_s` (callback seconds relative to take start). Cam1 is the scene view; cam2 is the wrist view. The empty `synchronized` group is not used.
The LeRobot conversion aligns camera/joint header stamps and command/gripper callback clocks using nearest timestamps. It retains all cam1 frames, with no servo-lag subtraction. State and action each contain six joints plus gripper. No depth was recorded.
`source_takes.json` preserves collection tags and episode order; `checksums.json` records SHA-256 for every raw recording file. No success labels or paper evaluation split are asserted.
