libero_plus_goal_texture_all
收藏资源简介:
该数据集是一个机器人学数据集,使用LeRobot创建,专注于Franka(Panda)机器人的多摄像头观察和动作记录。数据集包含864个总集数、105509个总帧数和10个总任务,数据以parquet文件格式存储。特征包括观察状态(如末端执行器状态、关节状态、夹爪状态)、多个视角的图像数据(如手腕图像、前视图图像、侧视图图像,均为256x256分辨率的RGB视频,帧率为20fps),以及动作信息(7维浮点数)。数据集结构还包括时间戳、帧索引、集索引和任务索引等元数据,适用于机器人控制和模仿学习任务。
This is a robotics dataset developed with LeRobot, focusing on multi-camera observation and action recording for the Franka (Panda) robot. It contains 864 total episodes, 105,509 total frames and 10 distinct tasks, with all data stored in Parquet file format. The features include observation states (such as end-effector states, joint states and gripper states), image data from multiple perspectives including wrist images, front-view images and side-view images, all of which are 256×256 resolution RGB videos with a frame rate of 20 fps, as well as 7-dimensional floating-point action information. The dataset structure also includes metadata such as timestamps, frame indices, episode indices and task indices, which is applicable to robotic control and imitation learning tasks.
