+- **Task Objective:** Operate the Z1 dual-arm robotic system to execute T-shirt folding tasks.
+- **Operational Objects:** T-shirt with the Unitree logo
+- **Operation Duration:** Each operation takes approximately 100 to 200 seconds.  
+- **Recording Frequency:** 30 Hz.  
+- **Robot Type:** Z1 7-DOF robotic arm with parallel gripper.  
+- **End Effector:** Parallel gripper.  
+- **Dual-Arm Operation:** Yes.  
+- **Image Resolution:** 640x480.  
+- **Camera Positions:** Mount a monocular camera at the end of each robotic arm; position two additional monocular cameras side-by-side at the midpoint between the two arms, 40cm above the work surface.  
+- **Data Content:**  
+ • Robot's current state.  
+ • Robot's next action.  
+ • Current camera view images.  
+- **Robot Initial Posture:** The first robot state in each dataset entry.  
+- **Object Placement:** Position the two robotic arms spaced approximately 60cm apart. Place the T-shirt within the reachable workspace of the dual robotic arms.
