G1_Dex3_ToastedBread_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:** Part 1: Place the bread from the serving tray into the toaster. Part 2: After the bread is toasted, hand the toast to the human.
- **Operational Objects:** Bread and Toaster（Purchase link: [【淘宝】7天无理由退货 https://e.tb.cn/h.60Va2WXFUDHazdQ?tk=uzwkeJCxTWW MF278 「苏泊尔DJ805烤面包机吐司机小型家用早餐机多士炉烤吐司三明治机」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 to 40 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 toaster and serving tray within the fully extended reach of the robotic arm, positioned at approximately a ​45-degree angle relative to the robot.
- **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.

- **操作时长：** 单次操作耗时约20至40秒。
- **录制帧率：** 30 Hz。
- **机器人类型：** 7自由度双臂G1机器人。
- **末端执行器：** 三指灵巧手。
- **双臂操作：** 是。
- **图像分辨率：** 640×480。
- **相机布局：** 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
• 当前相机视角下的图像
- **机器人初始姿态：** 每个数据集条目中的首个机器人状态。
- **物体摆放：** 将烤面包机与餐盘放置于机械臂完全可达范围内，与机器人呈约45度夹角。
- **相机视角：** 遵循[AVP远程操作文档](https://github.com/unitreerobotics/avp_teleoperate)的第5部分指南。

- **重要说明：**
1. 由于无法精准描述空间位置，请在按照[AVP远程操作文档](https://github.com/unitreerobotics/avp_teleoperate)的第5部分完成硬件安装后，调整场景以尽可能匹配数据集的首帧画面。
2. 数据采集并非单次完成，不同数据集条目之间存在差异，请在模型训练过程中考虑此类差异。
