record-test-4

该数据集使用LeRobot工具创建，专注于机器人技术领域，针对omx_follower机器人类型。它包含机器人的动作和观察状态数据：动作特征由6个浮点数值组成，分别表示肩部平移、肩部提升、肘部弯曲、腕部弯曲、腕部旋转和夹爪位置；观察状态特征同样包括这些关节位置，以及来自前置摄像头的图像数据（分辨率为480x640，3通道）。数据以Parquet文件组织，包含时间戳、帧索引、剧集索引等元数据，帧率为30 fps。该数据集可能用于机器人控制、模仿学习或强化学习任务，但具体应用场景和任务目标未在README中明确说明。

This dataset is created using LeRobot and focuses on the robotics domain, specifically for the omx_follower robot type. It includes robot action and observation state data: the action features consist of 6 floating-point values representing shoulder translation, shoulder lift, elbow bend, wrist bend, wrist rotation, and gripper position; the observation state features similarly include these joint positions, along with image data from a front-facing camera (resolution 480x640, 3 channels). The data is organized in Parquet files with metadata such as timestamps, frame indices, and episode indices, and has a frame rate of 30 fps. It may be used for robot control, imitation learning, or reinforcement learning tasks, but specific application scenarios and task objectives are not explicitly stated in the README.
