lerobot_dataset_b
收藏资源简介:
该数据集是一个由LeRobot创建的机器人数据集,专门用于机器人任务。它包含4个总剧集、2321个总帧和1个总任务,数据以parquet格式存储,视频以mp4格式存储。机器人类型为so_follower,特征包括动作(如肩部平移、肩部升降、肘部弯曲、腕部弯曲、腕部滚动和夹爪位置)、观察状态(与动作相同)、观察图像(来自前置摄像头,分辨率为480x640,3通道,30帧/秒),以及时间戳、帧索引、剧集索引、索引和任务索引等元数据。数据集结构详细,适用于机器人控制和模仿学习任务。
This dataset is a robot dataset created by LeRobot, specifically designed for robot tasks. It contains 4 total episodes, 2321 total frames, and 1 total task, with data stored in parquet format and videos in mp4 format. The robot type is so_follower, and features include actions (such as shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist roll, and gripper position), observation states (same as actions), observation images (from a front-facing camera with a resolution of 480x640, 3 channels, 30 frames per second), and metadata such as timestamps, frame indices, episode indices, indices, and task indices. The dataset is structured in detail and is suitable for robot control and imitation learning tasks.
