收藏资源简介:
该数据集是一个用于机器人操作任务的开源数据集,具体任务为在冰箱中交换烧杯,使用LeRobot框架创建,旨在为机器人学习提供真实的操作演示数据。数据集包含102个完整情节,总计97,687帧数据,以30 FPS的帧率采集,采用分块存储,总数据文件大小约为100 MB,视频文件大小约为200 MB。数据特征包括动作指令(一个16维的浮点向量,控制左右机械臂的各个关节位置以及底盘的速度)和观测信息(机器人本体状态,包括16维的关节位置和速度信息,以及来自三个摄像头的视觉信息:一个高位固定摄像头和两个分别安装在左右机械腕部的摄像头)。所有摄像头视频的分辨率均为640x480,3通道彩色,采用H.264编码。此外,每条数据还包含时间戳、帧索引、情节索引、任务索引等元数据。数据集适用于机器人模仿学习、强化学习、视觉运动策略学习等研究领域,特别是涉及双臂协调、精细操作以及在受限空间(如冰箱)内进行物体重排的任务。数据集采用Apache-2.0许可证发布。
This dataset is an open-source dataset for robot manipulation tasks, specifically the task of exchanging beakers in a refrigerator. It is created using the LeRobot framework and aims to provide real-world demonstration data for robot learning. The dataset contains 102 complete episodes, totaling 97,687 frames collected at 30 FPS, and is stored in chunks with a total data file size of approximately 100 MB and a video file size of approximately 200 MB. The data features include action commands (a 16-dimensional floating-point vector controlling the joint positions of the left and right robotic arms and the base velocity) and observation information (robot body state, including 16-dimensional joint positions and velocities, as well as visual information from three cameras: a high fixed camera and two cameras mounted on the left and right robotic wrists). All camera videos have a resolution of 640x480, 3-channel color, and use H.264 encoding. Additionally, each data entry includes metadata such as timestamps, frame indices, episode indices, and task indices. The dataset is suitable for research areas such as robot imitation learning, reinforcement learning, and visual-motor policy learning, particularly for tasks involving dual-arm coordination, fine manipulation, and object rearrangement in constrained spaces (e.g., a refrigerator). The dataset is released under the Apache-2.0 license.
