收藏资源简介:
该数据集是一个机器人控制数据集,由LeRobot创建。它包含50个episodes,总计27387帧数据,以30fps的帧率采集。数据结构包括动作(action)和观察状态(observation.state),各由6个浮点值组成,分别表示机器人关节位置(如肩部平移、肩部升降、肘部弯曲、腕部弯曲、腕部旋转和夹爪位置)。观察部分还包括前视图像(observation.images.front),为视频数据,分辨率为480x640,具有3个颜色通道,使用av1编解码器。此外,数据集包含时间戳、帧索引、episode索引、任务索引等元数据。机器人类型为so_follower,数据文件以parquet格式存储,总大小约100MB,视频文件总大小约200MB。数据集已划分为训练集,包含全部50个episodes。
This dataset is a robot control dataset created by LeRobot. It contains 50 episodes, totaling 27,387 frames, collected at a frame rate of 30fps. The data structure includes actions (action) and observation states (observation.state), each consisting of 6 floating-point values representing robot joint positions (such as shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, and gripper position). The observation part also includes front-view images (observation.images.front), which are video data with a resolution of 480x640, 3 color channels, and using the av1 codec. Additionally, the dataset contains metadata such as timestamps, frame indices, episode indices, and task indices. The robot type is so_follower, and the data files are stored in parquet format, with a total size of approximately 100MB, while the video files total about 200MB. The dataset is divided into a training set, comprising all 50 episodes.
