lerobot_arm_3
收藏资源简介:
这是一个使用LeRobot工具创建的机器人数据集,专为机器人控制任务设计。数据集包含50个episodes,总计13038帧数据,采样频率为30fps。特征包括:动作向量(10维浮点型,表示机械臂关节位置和速度)、状态观测(10维浮点型,表示机械臂和底盘关节位置)、多视角图像观测(前视、侧视、俯视三个视角的480x640x3视频,编码为h264格式),以及时间戳、帧索引、episode索引等元数据。数据集以Parquet文件格式存储,总数据量约300MB(包括数据和视频),适用于机器人强化学习或模仿学习任务。
This is a robot dataset created using the LeRobot tool, primarily designed for robot control tasks. The dataset contains 50 episodes, totaling 13038 frames with a sampling frequency of 30fps. Features include: action vectors (10-dimensional floating-point, representing robotic arm joint positions and velocities), state observations (10-dimensional floating-point, representing robotic arm and base joint positions), multi-view image observations (videos from three perspectives: front, side, and top, with resolution 480x640x3, encoded in h264 format), as well as metadata such as timestamps, frame indices, and episode indices. The dataset is stored in Parquet format, with a total data size of approximately 300MB (including data and videos), and is suitable for robot reinforcement learning or imitation learning tasks.
