收藏资源简介:
该数据集由LeRobot创建,专注于机器人学任务,特别是打开抽屉的操作。数据集包含20个片段,总计8359帧,帧率为每秒30帧。数据特征包括机器人的动作(如肩部、肘部、腕部和夹爪的位置)、观察状态(与动作相同的关节位置)、前视图和顶视图的图像观察(分辨率为480x640,3通道,视频编码为av1),以及时间戳、帧索引、片段索引、索引和任务索引等元数据。机器人类型为so_follower,数据集用于训练或评估机器人控制模型,支持多模态输入(如关节状态和视觉信息)。数据以Parquet文件格式存储,视频以MP4格式存储,总数据文件大小为100MB,视频文件大小为200MB。
This dataset was created by LeRobot, focusing on robotics tasks, particularly drawer-opening operations. It comprises 20 segments with a total of 8359 frames, at a frame rate of 30 frames per second. The dataset features include robot joint actions (positions of the shoulder, elbow, wrist, and gripper), observation states (identical joint positions to the corresponding actions), visual observations from the front view and top view (480x640 resolution, 3-channel, with AV1 video encoding), as well as metadata such as timestamps, frame index, segment index, sample index, and task index. The robot type is so_follower. This dataset is designed for training or evaluating robot control models, and supports multimodal inputs including joint states and visual information. The data is stored in Parquet file format, while the videos are stored in MP4 format. The total size of the data files is 100 MB, and the total size of the video files is 200 MB.
