dual-arm-dataset16
收藏资源简介:
该数据集是使用LeRobot框架创建的双机械臂机器人数据集,专门用于机器人学研究和应用。它记录了机器人执行任务时的多模态数据,包括:12维的动作向量(控制左右机械臂的关节位置和夹爪位置)、12维的观测状态向量(反映左右机械臂的当前关节位置和夹爪位置)、以及来自三个摄像头的视频观测(顶部摄像头和左右手腕摄像头,分辨率均为480x640,3通道彩色视频,帧率30fps)。此外,数据集还包含时间戳、帧索引、episode索引等元数据。总共有1个episode,295帧数据,数据以parquet格式存储,视频采用av1编码。机器人类型为so101_dual_follower,适用于训练和评估双机械臂控制算法。
This dataset is a dual-arm robot dataset created using the LeRobot framework, specifically designed for robotics research and applications. It records multimodal data during robot task execution, including: a 12-dimensional action vector (controlling joint positions and gripper positions for both left and right arms), a 12-dimensional observation state vector (reflecting current joint positions and gripper positions for both arms), and video observations from three cameras (top camera and left/right wrist cameras, all with a resolution of 480x640, 3-channel color video, at 30 fps). Additionally, the dataset includes metadata such as timestamps, frame indices, and episode indices. It consists of 1 episode with 295 frames of data, stored in parquet format, with videos encoded in av1. The robot type is so101_dual_follower, suitable for training and evaluating dual-arm control algorithms.
