收藏资源简介:
该数据集是一个机器人数据集,使用LeRobot创建,专注于机器人任务。它包含50个episodes,总计25317帧数据,帧率为30fps。数据集结构包括动作(action)和观察状态(observation.state),动作和状态均为6维浮点数组,表示机器人关节位置(如肩部平移、肩部提升、肘部弯曲、手腕弯曲、手腕旋转和夹爪位置)。观察部分包括两个摄像头视频:手腕摄像头(wrist)和顶部摄像头(top),视频分辨率为480x640,3通道(RGB),编码为AV1格式。此外,还包含时间戳、帧索引、episode索引、任务索引等元数据。数据集用于训练和评估机器人控制模型,机器人类型为“so_follower”。数据以Parquet文件存储,视频以MP4文件存储,总数据大小约为300MB(数据文件100MB,视频文件200MB)。
This is a robotics dataset created using LeRobot, focusing on robotic tasks. It contains 50 episodes, totaling 25317 frames with a frame rate of 30 fps. The dataset structure includes action and observation.state, both of which are 6-dimensional floating-point arrays representing robot joint positions (e.g., shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, and gripper position). The observation section includes two camera videos: the wrist camera and the top camera, with a resolution of 480×640, 3-channel RGB, encoded in the AV1 format. Additionally, it contains metadata such as timestamps, frame indices, episode indices, and task indices. This dataset is used for training and evaluating robotic control models, with the target robot type being "so_follower". The numerical data is stored in Parquet files, while the video files are stored in MP4 format, with a total size of approximately 300 MB (100 MB for data files and 200 MB for video files).
