资源简介:

该数据集使用LeRobot创建,是一个机器人学领域的数据集,专门用于机器人控制和学习任务。数据集包含多模态数据:动作数据为9维浮点向量,表示机器人手臂关节位置和速度(包括肩部平移、肩部提升、肘部弯曲、手腕弯曲、手腕旋转、夹爪位置,以及x、y和θ方向的速度);状态观测数据同样为9维浮点向量,与动作数据具有相同的维度结构;图像观测数据包括前视摄像头视频(分辨率480x640,3通道)和腕部摄像头视频(分辨率640x480,3通道),均以AV1编码的mp4格式存储,帧率为120fps。此外,数据集还包含时间戳、帧索引、任务索引、episode索引等元数据。数据集总共有2个episodes,2188帧,1个任务,数据以parquet文件分块存储(每块1000帧),总数据文件大小为100MB,视频文件大小为200MB。数据集仅包含训练集,适用于机器人行为克隆、强化学习等研究。

This dataset is developed using LeRobot, targeting robotic control and learning tasks in the field of robotics. It contains multimodal data: the action data is 9-dimensional floating-point vectors representing the joint positions and velocities of the robotic arm, including shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, gripper position, as well as velocities in the x, y, and θ directions; the state observation data is also 9-dimensional floating-point vectors with the same dimensional structure as the action data; the image observation data includes front-facing camera videos (resolution 480x640, 3-channel) and wrist camera videos (resolution 640x480, 3-channel), both stored in AV1-encoded MP4 format with a frame rate of 120 fps. Additionally, the dataset includes metadata such as timestamps, frame indices, task indices, and episode indices. In total, the dataset has 2 episodes, 2188 frames, and 1 task. The data is stored in chunked Parquet files (1000 frames per chunk), with a total data file size of 100 MB and a total video file size of 200 MB. The dataset only contains a training set and is suitable for research on robotic behavior cloning, reinforcement learning, and other related fields.
