收藏资源简介:
这是一个机器人学数据集,使用LeRobot工具创建,专门用于机器人控制和学习任务。数据集包含60个总片段,总计39270帧,以30帧每秒的速率采集。数据特征包括:动作数据(6维浮点数组,表示机器人关节位置,如肩部平移、肩部升降、肘部弯曲、腕部弯曲、腕部旋转和夹爪位置);观测状态数据(与动作相同的6维关节位置);以及三个图像观测:顶部摄像头视频(分辨率480x640,3通道)、腕部摄像头视频(分辨率480x640,3通道)和触觉频谱图视频(分辨率224x224,3通道,基于dragonfly传感器在100kHz采样率和4096点FFT下生成)。此外,数据集还包括时间戳、帧索引、片段索引、索引和任务索引等元数据。机器人类型为so101_follower_dragon_tactile_bench,数据以parquet文件(用于结构化数据)和mp4视频文件存储,总数据大小约为300MB(数据文件100MB,视频文件200MB)。数据集仅包含训练分割,涵盖所有片段。
This is a robotics dataset created using the LeRobot tool, specifically designed for robot control and learning tasks. The dataset contains a total of 60 episodes, with 39,270 frames collected at a rate of 30 frames per second. Data features include: action data (6-dimensional floating-point arrays representing robot joint positions, such as shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, and gripper position); observation state data (6-dimensional joint positions identical to the actions); and three image observations: top camera video (resolution 480x640, 3 channels), wrist camera video (resolution 480x640, 3 channels), and tactile spectrogram video (resolution 224x224, 3 channels, generated based on a dragonfly sensor at 100kHz sampling rate with 4096-point FFT). Additionally, the dataset includes metadata such as timestamps, frame indices, episode indices, indices, and task indices. The robot type is so101_follower_dragon_tactile_bench, and data is stored in parquet files (for structured data) and mp4 video files, with a total data size of approximately 300MB (100MB for data files and 200MB for video files). The dataset only includes a training split, covering all episodes.
