nulldata-0
收藏资源简介:
该数据集由LeRobot创建,属于机器人领域,包含20个episodes,总计3260帧,涉及3个不同任务。数据以parquet文件格式存储,总数据量约100 MB,并附带视频文件,总大小约200 MB,视频帧率为30 fps。数据集结构包括:动作(action)和状态观测(observation.state)均为6维浮点向量,分别对应机器人的肩部平移、肩部抬升、肘部弯曲、腕部弯曲、腕部旋转和夹爪位置;观测图像包括顶部视角(observation.images.top)和腕部视角(observation.images.wrist)的视频,分辨率均为640x480,3通道彩色,使用av1编码;其他字段包括时间戳(timestamp)、帧索引(frame_index)、episode索引(episode_index)、全局索引(index)和任务索引(task_index)。该数据集适用于机器人学习任务,如模仿学习或强化学习。
This dataset is created by LeRobot and belongs to the robotics domain. It contains 20 episodes, totaling 3260 frames, and involves 3 different tasks. The data is stored in parquet format, with a total data size of approximately 100 MB, and includes corresponding video files with a total size of about 200 MB and a frame rate of 30 fps. The dataset structure includes: action and observation.state, both 6-dimensional floating-point vectors corresponding to the robots shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, and gripper position; observation images include videos from top view (observation.images.top) and wrist view (observation.images.wrist), both with a resolution of 640x480, 3-channel color, encoded with av1; other fields include timestamp, frame_index, episode_index, index, and task_index. The dataset is suitable for robotics learning tasks such as imitation learning or reinforcement learning.
