G1_Dex3_Pouring_Dataset

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:** Take the water bottle and simulate pouring water into a transparent glass cup.
- **Operational Objects:** Transparent glass cup (7cm diameter × 8cm height) + 350ml Wahaha bottled water (Purchase link: 【淘宝】https://e.tb.cn/h.60Y4A3cvIpzq2xO?tk=iMs8eJrmMWW CZ001 「娃哈哈 纯净水饮用水350ml*24瓶整箱瓶装企业会议用水」点击链接直接打开 或者 淘宝搜索直接打开).
- **Operation Duration:** Each operation takes approximately 20 seconds.
- **Recording Frequency:** 30 Hz.
- **Robot Type:** 7-DOF dual-arm G1 robot.
- **End Effector:** Three-fingered dexterous hands.
- **Dual-Arm Operation:** Yes.
- **Image Resolution:** 640x480.
- **Camera Positions:** Wrist-mounted (monocular camera) + head-mounted (binocular cameras).
- **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:** Place the water cup adjacent to the three-fingered dexterous hand on the robot's left arm in its initial position (arm vertical); position the water bottle within reach of the right hand.
- **Camera View:** Follow the guidelines in **Part 5** of [AVP Teleoperation Documentation](https://github.com/unitreerobotics/avp_teleoperate).

- **Important Notes:**
1. Due to the inability to precisely describe spatial positions, adjust the scene to closely match the first frame of the dataset after installing the hardware as specified in **Part 5** of [AVP Teleoperation Documentation](https://github.com/unitreerobotics/avp_teleoperate).
2. Data collection is not completed in a single session, and variations between data entries exist. Ensure these variations are accounted for during model training.

## 数据集说明

- **官网**：[更多信息待补充]
- **论文**：[更多信息待补充]
- **授权协议**：Apache 2.0

- **单次操作时长**：单次操作耗时约20秒。
- **录制帧率**：30Hz。
- **机器人类型**：7自由度（7-DOF）双臂G1机器人。
- **末端执行器（End Effector）**：三指灵巧手（Three-fingered dexterous hands）。
- **双臂操作**：是。
- **图像分辨率**：640×480。
- **相机部署位置**：腕部搭载单目相机 + 头部搭载双目相机。
- **数据内容**：
• 机器人当前状态
• 机器人下一动作
• 当前相机视角图像
- **机器人初始姿态**：每个数据集条目中的首个机器人状态即为初始姿态。
- **物体摆放位置**：初始状态下，将水杯放置在机器人左臂的三指灵巧手旁（左臂呈垂直姿态）；将水瓶放置在右臂可及范围内。
- **相机视角**：遵循[AVP遥操作文档](https://github.com/unitreerobotics/avp_teleoperate)第5部分的指南。

## 重要说明
1. 由于无法精准描述空间位置，请按照[AVP遥操作文档](https://github.com/unitreerobotics/avp_teleoperate)第5部分的要求安装硬件后，调整场景以尽可能匹配数据集的首帧画面。
2. 本次数据采集并非单次完成，不同数据条目间存在差异，在模型训练阶段需充分考虑此类差异。
