so100_strawberry_2
收藏资源简介:
这是一个基于LeRobot框架创建的机器人操作数据集,采用Apache-2.0许可证。数据集包含50个episode,共计70,492帧,帧率为30fps,仅包含一个任务。数据由一台名为so100_follower的机器人采集,记录其6个关节(shoulder_pan、shoulder_lift、elbow_flex、wrist_flex、wrist_roll和gripper)的位置信息。每个时间步包含:6维动作向量、6维观察状态向量,以及来自三个摄像头(front、top、hand)的彩色视频图像(分辨率480x640,RGB三通道)。此外还提供时间戳、帧索引、episode索引、索引和任务索引等辅助字段。数据文件以Parquet格式存储,视频文件以MP4格式存储,总大小约300MB。数据集可用于机器人模仿学习、行为克隆、策略训练等任务。根据数据集名称推测,任务可能涉及草莓的抓取或操作。
This is a robot manipulation dataset created based on the LeRobot framework, licensed under Apache-2.0. The dataset contains 50 episodes, totaling 70,492 frames at 30fps, with only one task. Data was collected by a robot named so100_follower, recording the positions of its 6 joints (shoulder_pan, shoulder_lift, elbow_flex, wrist_flex, wrist_roll, and gripper). Each timestep includes: a 6-dimensional action vector, a 6-dimensional observation state vector, and color video images (resolution 480x640, RGB three channels) from three cameras (front, top, hand). Additional auxiliary fields such as timestamps, frame indices, episode indices, indices, and task indices are provided. Data files are stored in Parquet format, video files in MP4 format, with a total size of approximately 300MB. The dataset can be used for tasks such as robot imitation learning, behavior cloning, and policy training. Based on the dataset name, it is speculated that the task may involve grasping or manipulating strawberries.
