收藏资源简介:
该数据集是一个机器人数据集,使用LeRobot创建。它包含1个episode,共1019帧,总数据文件大小为100MB,视频文件大小为200MB。数据集的特征包括:动作(9维浮点数,表示手臂关节位置和速度)、状态观测(9维浮点数,与动作相同)、前摄像头图像(480x640x3视频)和腕部摄像头图像(480x640x3视频),以及时间戳、帧索引、episode索引、索引和任务索引等元数据。机器人类型为lekiwi_client,帧率为15fps。数据以Parquet格式存储,视频以MP4格式存储,使用av1编解码器。数据集用于机器人任务,如控制和学习,但具体任务未详细说明。
This is a robotics dataset constructed using LeRobot. It includes 1 episode, comprising a total of 1019 frames. The total size of the non-video data files is 100 MB, while the video files have a combined size of 200 MB. The dataset features the following components: actions (9-dimensional floating-point values representing arm joint positions and velocities), state observations (9-dimensional floating-point values identical to the actions), front-facing camera images (480×640×3 videos), wrist camera images (480×640×3 videos), as well as metadata such as timestamps, frame indices, episode indices, indexes, and task indices. The robot platform is lekiwi_client, with a frame rate of 15 fps. The tabular data is stored in Parquet format, whereas the videos are saved in MP4 format using the AV1 codec. This dataset is designed for robotics-related tasks including robot control and learning, though the specific tasks are not elaborated in detail.
