资源简介:

该数据集由LeRobot创建,是一个专门用于双手机器人操作任务的机器人学数据集。它包含201个episodes,总计265,875帧,涉及2个不同任务。数据以parquet格式存储,视频以mp4格式存储,帧率为50Hz。数据集特征包括:动作(12个关节位置,对应左右肩、肘、腕和夹爪)、观测状态(12个关节位置),以及三个摄像头图像(左夹爪左、左中、右夹爪右),每个图像分辨率为480x640,3通道。此外,还包含时间戳、帧索引、episode索引、任务索引等元数据。机器人类型为bi_so_follower,适用于机器人控制、模仿学习等研究领域。

This dataset was developed by LeRobot, and it is a robotics dataset specifically tailored for dual-arm robotic manipulation tasks. It comprises 201 episodes, with a total of 265,875 frames across 2 distinct tasks. The tabular data is stored in Parquet format, while the corresponding videos are saved in MP4 format at a frame rate of 50 Hz. The dataset includes the following features: actions (12 joint positions corresponding to the left and right shoulders, elbows, wrists, and grippers), observation states (12 joint positions), and three camera images (left gripper left view, left-middle view, right gripper right view). Each image has a resolution of 480x640 with 3 color channels. Additionally, it contains metadata such as timestamps, frame indices, episode indices, and task indices. The robotic platform is bi_so_follower, and this dataset is suitable for research areas such as robotic control and imitation learning.
