lekiwi_pick_sim_real_merged
收藏资源简介:
该数据集由LeRobot项目创建,是一个用于机器人学习的数据集,结合了仿真和真实世界数据。数据集包含200个episodes,总计80,898帧,涉及2个任务。数据以parquet格式存储,每帧包含动作数据(9维浮点数组,表示机械臂关节位置和末端执行器速度)、状态观测(与动作相同的9维数组)、图像观测(前视摄像头480x640 RGB视频和腕部摄像头640x480 RGB视频,均为30fps),以及时间戳、帧索引、episode索引等元数据。机器人类型为lekiwi,数据集总大小约为300MB(数据100MB,视频200MB)。
This dataset is created by the LeRobot project and is designed for robot learning, combining simulation and real-world data. It contains 200 episodes, totaling 80,898 frames, covering 2 tasks. The data is stored in parquet format, with each frame including action data (a 9-dimensional floating-point array representing robot arm joint positions and end-effector velocities), state observations (a 9-dimensional array similar to the action), image observations (front-view camera 480x640 RGB video and wrist camera 640x480 RGB video, both at 30fps), as well as metadata such as timestamps, frame indices, and episode indices. The robot type is lekiwi, and the total dataset size is approximately 300MB (100MB for data and 200MB for video).
