收藏资源简介:
该数据集是一个机器人操作数据集,使用LeRobot框架创建,专门用于拾放任务。数据集包含266个完整操作序列,总计61366帧数据,以30fps的频率采集。数据采用Parquet文件格式存储,总数据量约为300MB(其中结构化数据100MB,视频数据200MB)。数据集的核心特征包括:1) 观测状态:包含7个机械臂关节位置(lj0-lj6),数据类型为float32;2) 动作指令:包含7个关节位置和1个左夹爪开合状态,共8维float32向量;3) 多视角视觉观测:包含zed和fish0两个相机视角的RGB视频,分辨率均为360x640,3通道,H.264编码,30fps;4) 时序与索引信息:时间戳、帧索引、序列索引、任务索引等。该数据集适用于机器人模仿学习、强化学习、行为克隆等研究,特别是机械臂抓取与放置任务的算法开发与评估。
This robotic manipulation dataset was developed using the LeRobot framework, specifically tailored for pick-and-place tasks. The dataset contains 266 complete manipulation sequences, totaling 61,366 frames collected at 30 fps. The data is stored in Parquet file format, with an overall size of approximately 300 MB (100 MB of structured data and 200 MB of video data). The core features of the dataset are listed below: 1) Observation state: includes 7 robotic arm joint positions (lj0-lj6) with a data type of float32; 2) Action commands: consists of 7 joint positions and 1 left gripper open/close state, forming an 8-dimensional float32 vector; 3) Multi-view visual observations: provides RGB videos from two camera perspectives (zed and fish0), both with a resolution of 360×640, 3 color channels, encoded in H.264 format, and captured at 30 fps; 4) Temporal and index information: includes timestamps, frame index, sequence index, task index, etc. This dataset is applicable to research fields such as robotic imitation learning, reinforcement learning and behavioral cloning, and is particularly suitable for algorithm development and evaluation of robotic arm grasping and pick-and-place tasks.
