so101_cube_pick_and_place_v3_combined
收藏资源简介:
该数据集由LeRobot项目创建,专注于机器人控制任务,具体涉及立方体的拾取与放置操作。数据集包含27966帧数据,组织为100个episodes和1个任务。数据以.parquet文件格式存储,并附有对应的MP4视频文件,总数据量约300MB。每个样本包含机器人的动作指令(6维关节位置:肩部平移/升降、肘部弯曲、腕部弯曲/旋转、夹爪位置)、观测状态(与动作相同的6维关节位置)、两个视角的视觉观测(顶部和腕部摄像头,分辨率480x640、30fps、AV1编码的RGB视频),以及时间戳、帧索引、episode索引等元数据。数据集适用于机器人模仿学习、视觉运动控制等任务,采用Apache-2.0许可证。
This dataset is created by the LeRobot project, focusing on robot control tasks, specifically involving pick-and-place operations of cubes. It contains 27,966 frames of data, organized into 100 episodes and 1 task. The data is stored in .parquet file format and comes with corresponding MP4 video files, totaling approximately 300MB. Each sample includes robot action commands (6-dimensional joint positions: shoulder translation/lift, elbow bend, wrist bend/rotation, gripper position), observation states (same 6-dimensional joint positions as actions), visual observations from two perspectives (top and wrist cameras, with 480x640 resolution, 30fps, AV1-encoded RGB video), as well as metadata such as timestamps, frame indices, and episode indices. The dataset is suitable for tasks like robot imitation learning and visual-motor control, and it is licensed under Apache-2.0.
