收藏资源简介:
这是一个使用LeRobot创建的机器人学数据集,专门用于强化学习或机器人策略训练。数据集基于panda机器人,包含32个episodes,总计3036帧数据,以parquet格式存储。数据特征包括观察图像(如主图像和手腕图像,均为256x256x3的视频帧,帧率10fps)、机器人状态(8维浮点数组)、动作(7维浮点数组)、奖励、完成标志、截断标志等。数据集还包含干预标志、时间戳、帧索引、episode索引等元数据,适用于机器人控制任务的研究和开发。
This is a robotics dataset created using LeRobot, specifically designed for reinforcement learning or robot policy training. The dataset is based on the panda robot, containing 32 episodes with a total of 3036 frames of data, stored in parquet format. Data features include observation images (such as main images and wrist images, both as video frames of size 256x256x3 with a frame rate of 10fps), robot state (8-dimensional floating-point array), actions (7-dimensional floating-point array), rewards, completion flags, truncation flags, etc. The dataset also includes metadata such as intervention flags, timestamps, frame indices, and episode indices, making it suitable for research and development in robot control tasks.
