LeRobot re-release of aytsaiusc/play_human_v3_3 with right-hand end-effector annotations from
phantom (HaMeR) + smoothing.
3D EEF is in the ROBOT-WORLD frame (one shared coordinate system with the
robot datasets), pinned onto the robot's locked tabletop plane: x/y from the
reliable 2D thumb-index fingertip midpoint (ray-plane intersection), z fixed to
z_plane = 0.10024 m (mean of robot v3 action z).
3 keypoints (wrist/thumb/index) are also given as 2D pixels… See the full description on the dataset page:
