收藏资源简介:
该数据集由LeRobot创建,专注于机器人任务,具体针对omx_follower机器人类型。数据集包含50个训练集,总计14048帧,帧率为30fps。数据以Parquet格式存储,并包含视频文件。特征包括动作(action)和观测状态(observation.state),均表示为6维浮点数组,对应机器人关节位置(如肩部平移、肩部提升、肘部弯曲、手腕弯曲、手腕滚动和夹爪位置)。观测图像(observation.images.front)为前视摄像头视频,分辨率为720x1280,3通道,编码为av1。此外,还包括时间戳、帧索引、集索引等元数据。数据集用于机器人控制或模仿学习任务,但具体应用场景未在README中详细说明。
This dataset is created by LeRobot and focuses on robotic tasks, specifically for the omx_follower robot type. It contains 50 training sets, totaling 14,048 frames with a frame rate of 30fps. The data is stored in Parquet format and includes video files. Features include action and observation.state, both represented as 6-dimensional floating-point arrays corresponding to robot joint positions (e.g., shoulder translation, shoulder elevation, elbow bend, wrist bend, wrist roll, and gripper position). The observation image (observation.images.front) is a front-view camera video with a resolution of 720x1280, 3 channels, encoded as av1. Additionally, metadata such as timestamps, frame indices, and episode indices are included. The dataset is intended for robotic control or imitation learning tasks, but specific application scenarios are not detailed in the README.
