收藏资源简介:
该数据集由LeRobot平台创建,属于机器人领域,包含80个episodes,总计49598帧数据,涵盖1个任务。数据以Parquet文件格式存储,并包含视频文件。核心特征包括:动作数据(action),为6维浮点数组,表示机械臂的关节位置(包括肩部平移、肩部抬升、肘部弯曲、腕部弯曲、腕部旋转和夹爪位置);观测状态(observation.state),同样为6维关节位置;观测图像包括机械臂视角(observation.images.arm)和俯视视角(observation.images.overhead)的视频,分辨率均为480x640,3通道彩色,帧率为30fps,使用AV1编码。此外,数据集还包含时间戳、帧索引、episode索引、任务索引等元数据字段。数据总大小约为300MB(其中结构化数据100MB,视频数据200MB),适用于机器人控制、模仿学习、视觉-动作策略学习等任务。
This dataset is created by the LeRobot platform and belongs to the robotics domain. It contains 80 episodes, totaling 49,598 frames of data, covering 1 task. The data is stored in Parquet file format and includes video files. Core features include: action data (action), which is a 6-dimensional floating-point array representing the joint positions of the robotic arm (including shoulder translation, shoulder lift, elbow bend, wrist bend, wrist rotation, and gripper position); observation state (observation.state), also a 6-dimensional joint position; observation images include videos from the robotic arm perspective (observation.images.arm) and overhead perspective (observation.images.overhead), both with a resolution of 480x640, 3-channel color, a frame rate of 30fps, and encoded using AV1. Additionally, the dataset includes metadata fields such as timestamps, frame indices, episode indices, and task indices. The total data size is approximately 300MB (with 100MB for structured data and 200MB for video data), and it is suitable for tasks such as robot control, imitation learning, and vision-action policy learning.
