收藏资源简介:
该数据集是使用LeRobot创建的机器人数据集,主要用于机器人技术任务。数据集包含一个剧集,总共有1221帧数据,涉及一个任务。数据特征包括:动作(action),包含6个浮点数,表示机器人关节位置(如肩部平移、肩部提升、肘部弯曲、腕部弯曲、腕部旋转、夹爪位置);观测状态(observation.state),与动作类似,也包含6个浮点数表示关节位置;观测图像(observation.images.overhead),为视频格式,分辨率480x640,3通道(RGB),帧率30fps,使用AV1编解码器;此外还有时间戳(timestamp)、帧索引(frame_index)、剧集索引(episode_index)、索引(index)和任务索引(task_index)等元数据。数据以Parquet文件格式存储,总数据文件大小为100MB,视频文件大小为200MB。机器人类型为so_follower。数据集采用Apache 2.0许可证。
This is a robotics dataset created using LeRobot, primarily intended for robotics technical tasks. It contains one episode with a total of 1221 frames for a single task. The dataset's data features include: the action field, which is a 6-element float array representing robot joint positions including shoulder translation, shoulder lift, elbow flexion, wrist flexion, wrist rotation, and gripper position; the observation state (observation.state), which is similar to the action field and also consists of a 6-element float array of joint positions; the observation images (observation.images.overhead), which are in video format with a resolution of 480x640, 3-channel RGB, 30 frames per second (fps), and use the AV1 codec; additionally, metadata such as timestamp, frame_index, episode_index, index, and task_index are included. The dataset is stored in Parquet file format, with a total data file size of 100 MB and a total video file size of 200 MB. The robot type used is so_follower, and the dataset is licensed under the Apache 2.0 license.
