收藏资源简介:
该数据集由LeRobot创建,专用于机器人学领域,采用ALOHA机器人类型。数据集包含103个episodes,总计89698帧,数据以parquet格式存储,并附带视频文件。特征包括机器人状态观测(14维浮点数,表示左右机械臂的关节位置,如腰部、肩部、肘部等)、动作(14维浮点数,对应相同的关节控制)、以及多个视角的图像观测(包括顶部摄像头、左腕摄像头和右腕摄像头,每个视频分辨率为224x224,帧率为50fps,使用h264编码)。此外,还包含时间戳、帧索引、episode索引、任务索引等元数据。数据集仅用于训练,许可证为Apache-2.0。
This dataset is created by LeRobot and specifically designed for robotics, using the ALOHA robot type. It contains 103 episodes, totaling 89,698 frames, stored in parquet format with accompanying video files. Features include robot state observations (14-dimensional floats representing joint positions of left and right arms, such as waist, shoulder, elbow, etc.), actions (14-dimensional floats for corresponding joint control), and multi-view image observations (including top camera, left wrist camera, and right wrist camera, each video with a resolution of 224x224, frame rate of 50fps, encoded in h264). Additionally, metadata such as timestamps, frame indices, episode indices, and task indices are included. The dataset is intended for training only, under the Apache-2.0 license.
