收藏资源简介:
该数据集是一个用于机器人学习的数据集,使用LeRobot工具创建。它包含从Grabette机器人收集的数据,总共有3个episodes和979帧,帧率为50fps。数据集特征包括两个摄像头的图像观测(每个图像分辨率为720x960,3通道),以及8维的动作向量(包括位置、方向和机械手控制)。数据以Parquet格式存储,并附带视频文件,适用于机器人控制、模仿学习或强化学习任务。许可证为Apache 2.0。
This dataset is designed for robotic learning and was created using the LeRobot toolkit. It contains data collected from the Grabette robot, with a total of 3 episodes and 979 frames at a frame rate of 50 fps. The dataset features image observations from two cameras, each with a resolution of 720×960 and 3 color channels, as well as an 8-dimensional action vector covering position, orientation, and gripper control. The data is stored in Parquet format, accompanied by video files, and is suitable for robotic control, imitation learning, or reinforcement learning tasks. The license is Apache 2.0.
