资源简介:
该数据集使用LeRobot创建,专为机器人学任务设计,包含17个episodes和23694帧数据。数据集以parquet格式存储,视频文件为mp4格式,帧率为30fps。数据特征包括动作(action)和观测状态(observation.state),均包含6个关节位置(如shoulder_pan.pos、shoulder_lift.pos、elbow_flex.pos、wrist_flex.pos、wrist_roll.pos、gripper.pos),以及两个视角的图像观测(front和top),分辨率为480x640x3。此外,还包括时间戳、帧索引、episode索引、索引和任务索引等元数据。数据集适用于机器人控制和学习任务,如模仿学习或强化学习。
This dataset is created using LeRobot and is specifically designed for robotics tasks, containing 17 episodes and 23,694 frames. The dataset is stored in parquet format, with video files in mp4 format and a frame rate of 30fps. Data features include actions (action) and observation states (observation.state), both containing 6 joint positions (e.g., shoulder_pan.pos, shoulder_lift.pos, elbow_flex.pos, wrist_flex.pos, wrist_roll.pos, gripper.pos), as well as image observations from two perspectives (front and top) with a resolution of 480x640x3. Additionally, metadata such as timestamps, frame indices, episode indices, indices, and task indices are included. The dataset is suitable for robot control and learning tasks, such as imitation learning or reinforcement learning.
