收藏资源简介:
该数据集是使用LeRobot创建的机器人学数据集,专门用于机器人控制和学习任务。它包含一个episode,总共有231帧数据,以20帧每秒的速率采集。数据集的特征包括观察状态(7个浮点数,表示关节位置如肩部平移、肩部提升、肘部弯曲、腕部弯曲、腕部滚动、夹爪位置和倾斜位置)、来自三个摄像头的图像观察(顶部、腕部和基础摄像头,每个摄像头提供480x640x3的视频数据,使用AV1编解码器),以及动作(7个浮点数,对应相同的关节位置)。此外,还包括时间戳、帧索引、episode索引、索引和任务索引等元数据。数据以parquet文件格式存储,总数据文件大小为100MB,视频文件大小为200MB。数据集适用于训练和评估机器人策略,特别是与VibeBoard跟随器倾斜机器人类型相关的任务。
This dataset is a robotics dataset created using LeRobot, specifically designed for robot control and learning tasks. It contains one episode with a total of 231 frames, collected at a rate of 20 frames per second. The dataset features include observation states (7 floating-point numbers representing joint positions such as shoulder pan, shoulder lift, elbow bend, wrist bend, wrist roll, gripper position, and tilt position), image observations from three cameras (top, wrist, and base cameras, each providing 480x640x3 video data using the AV1 codec), and actions (7 floating-point numbers corresponding to the same joint positions). Additionally, it includes metadata such as timestamps, frame index, episode index, index, and task index. The data is stored in parquet file format, with a total data file size of 100MB and a video file size of 200MB. The dataset is suitable for training and evaluating robot policies, particularly for tasks related to the VibeBoard follower tilt robot type.
