cube_v2_pi
收藏资源简介:
该数据集是一个机器人操作数据集,使用LeRobot工具创建,专注于机器人双臂控制任务,适用于机器人学习和模仿学习研究。数据内容包括动作数据和观测数据:动作数据为12维浮点数向量,表示左右机械臂各6个关节(肩部平移、肩部升降、肘部弯曲、腕部弯曲、腕部旋转、夹爪)的位置控制指令;观测数据分为状态观测(记录12个关节实际位置)和视觉观测(包含三个固定视角的视频流:左臂腕部视角、顶部俯视视角、右臂腕部视角,所有视频分辨率为1280x720,帧率30fps,采用AV1编码)。此外,数据集还包含时间戳、帧索引、回合索引、任务索引等元数据。数据集规模为151个完整回合(episodes),共计137,937帧数据,对应一项任务,以分块Parquet文件格式存储,并已划分为训练集。机器人平台类型为bi_so_follower(推测为双臂从动机器人),遵循Apache 2.0开源协议。
This dataset is a robotic manipulation dataset created using the LeRobot tool, focusing on bimanual robot control tasks and suitable for robot learning and imitation learning research. The data includes action data and observation data: action data consists of a 12-dimensional floating-point vector representing position control commands for six joints each of the left and right robotic arms (shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, gripper); observation data is divided into state observations (recording the actual positions of the 12 joints) and visual observations (including three fixed-view video streams: left arm wrist view, top-down view, and right arm wrist view, all with a resolution of 1280x720, 30fps frame rate, and AV1 encoding). Additionally, the dataset contains metadata such as timestamps, frame indices, episode indices, and task indices. The dataset scale comprises 151 complete episodes, totaling 137,937 frames of data for one task, stored in chunked Parquet file format and partitioned into a training set. The robot platform type is bi_so_follower (presumed to be a bimanual follower robot), and it follows the Apache 2.0 open-source license.
