This dataset was created using [LeRobot](https://github.com/huggingface/lerobot).
## Dataset Description
- **Homepage:** [More Information Needed]
- **Paper:** [More Information Needed]
- **License:** apache-2.0
- **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.
