收藏资源简介:
该数据集使用LeRobot创建,专注于机器人领域。数据集包含一个episode,总帧数为450,涉及机器人so_follower。数据特征包括动作(如肩部、肘部、腕部和抓取器的位置)、观测状态(与动作相同的关节位置)、前视和腕部摄像头的视频观测(分辨率为480x640,3通道,帧率15fps,使用av1编码),以及时间戳、帧索引、episode索引等元数据。视频文件以mp4格式存储,数据以parquet格式组织,总数据大小约100MB,视频大小约200MB。数据集用于训练或评估机器人控制任务,支持从多模态观测中学习动作策略。
This dataset is created using LeRobot and focuses on the robotics domain. It contains one episode with a total of 450 frames, involving the robot so_follower. Data features include actions (such as positions of shoulders, elbows, wrists, and grippers), observation states (joint positions identical to actions), video observations from front-facing and wrist cameras (with a resolution of 480x640, 3 channels, frame rate of 15fps, encoded using av1), as well as metadata like timestamps, frame indices, and episode indices. Video files are stored in mp4 format, and data is organized in parquet format, with a total data size of approximately 100MB and video size of about 200MB. The dataset is used for training or evaluating robot control tasks, supporting learning action policies from multimodal observations.
