资源简介:
该数据集是一个用于机器人学的双机械臂数据集,由LeRobot创建。它记录了机器人执行任务时的动作、状态和多视角视觉数据。数据集包含2个episodes、6136帧和1个任务,数据以parquet格式存储,并附带视频文件。机器人类型为bi_openarm_follower(双开放臂跟随器)。动作数据包括左右机械臂各7个关节和夹爪的位置、速度和扭矩,共48维。观测状态数据与动作数据类似,提供机械臂的实时状态。观测图像数据来自多个摄像头:顶部RGB和深度摄像头(分辨率1280x720,30fps),以及左右腕部的RGB和深度摄像头(分辨率640x480,30fps)。这些数据可用于机器人控制、模仿学习或强化学习任务。
This dataset is a dual-arm robotic dataset for robotics research, developed by LeRobot. It records the robot's motion, states, and multi-view visual data during task execution. The dataset contains 2 episodes, 6136 frames, and one task. The data is stored in Parquet format, with accompanying video files. The robotic platform is bi_openarm_follower (dual open-arm follower). The action data covers position, velocity, and torque information for 7 joints and the gripper of each left and right robotic arm, totaling 48 dimensions. The observation state data is similar to the action data, providing real-time states of the robotic arms. The visual observation data comes from multiple cameras: a top-mounted RGB and depth camera with a resolution of 1280x720 at 30fps, as well as RGB and depth cameras mounted on the left and right wrists with a resolution of 640x480 at 30fps. This dataset can be applied to robotic control, imitation learning, and reinforcement learning tasks.
