 ## Dataset Description
 
 This is a fully annotated, synthetically generated dataset consisting of 1,000 demonstrations of a single Franka Panda robot arm performing a fixed-order three-cube stacking task in Isaac Lab. The robot consistently stacks cubes in the order: blue (bottom) → red (middle) → green (top).

 - 7D vector: 6D relative end-effector motion + 1D gripper action
 
 ### Observations
-- `robot_states`: Joint positions, velocities, and gripper open/close state
-- `ee_states`: End-effector 6-DOF pose
-- `cube_states`: 6-DOF poses (position + quaternion) for blue, red, and green cubes
-- `images.table_camera`:
+- Robot states: Joint positions, velocities, and gripper open/close state
