收藏资源简介:
本数据集是一个使用LeRobot工具创建的机器人操作数据集,专注于拾取与放置任务。它包含机器人执行任务时的多模态观测数据和动作指令,具体包括:动作指令(6维关节位置控制,涉及肩部平移、肩部抬升、肘部弯曲、腕部弯曲、腕部旋转和夹爪位置)、状态观测(6维关节位置反馈)、前视摄像头图像(480x640分辨率RGB视频,30fps)、标注图像(相同规格的标注视频)、时间戳、帧索引、episode索引和任务索引等。数据规模包括1个完整任务序列、1个子任务和7812个数据帧。视频数据采用AV1编码,YUV420p像素格式。数据集以Parquet文件格式存储,总数据文件大小为100MB,视频文件大小为200MB。机器人平台类型为so_follower,仅提供训练集划分,适用于机器人模仿学习、行为克隆和视觉运动策略学习等研究任务。
This dataset is a robotic manipulation dataset created using the LeRobot tool, focusing on pick-and-place tasks. It includes multimodal observation data and action instructions during robot task execution, specifically: action instructions (6-dimensional joint position control, covering shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, and gripper position), state observations (6-dimensional joint position feedback), front-view camera images (480x640 resolution RGB video at 30fps), annotated images (annotated video with the same specifications), timestamps, frame indices, episode indices, task indices, and more. The data scale comprises 1 complete task sequence, 1 subtask, and 7812 data frames. Video data uses AV1 encoding with YUV420p pixel format. The dataset is stored in Parquet file format, with a total data file size of 100MB and video file size of 200MB. The robot platform type is so_follower, providing only a training set split, and it is suitable for research tasks such as robot imitation learning, behavior cloning, and visual-motor policy learning.
