资源简介:
该数据集是一个专用于机器人学任务的数据集,旨在评估ACT-Trajectory-v2链的性能。它包含一个episode,共计510帧数据,采集自so_follower类型的机器人。数据集提供了丰富的机器人数据:动作数据为6维浮点数,分别对应肩部平移、肩部提升、肘部弯曲、腕部弯曲、腕部旋转和夹爪位置;观测状态同样为6维关节位置。此外,数据集还包括三个不同视角的图像视频观测:侧视、腕部视和轨迹视,每个视频的分辨率为480x640像素,3通道颜色,帧率为30fps。元数据方面,包含时间戳、帧索引、episode索引和任务索引等信息。数据以Parquet格式存储:总数据文件大小为100MB,视频文件大小为200MB。
This dataset is specifically designed for robotics tasks, aimed at evaluating the ACT-Trajectory-v2 chain. It contains one episode with a total of 510 frames, collected from a so_follower type robot. The dataset provides comprehensive robot data: action data consists of 6-dimensional floating-point numbers corresponding to shoulder translation, shoulder elevation, elbow flexion, wrist flexion, wrist rotation, and gripper position; observation state is also 6-dimensional joint positions. Additionally, the dataset includes image video observations from three perspectives: side view, wrist view, and trajectory view, each video with a resolution of 480x640 pixels, 3 color channels, and a frame rate of 30fps. Metadata includes timestamps, frame index, episode index, and task index. The data is stored in Parquet format: the total data file size is 100MB, and the video file size is 200MB.
