eval_act_5_15fps
收藏资源简介:
该数据集是一个用于机器人学习的双臂机器人(bi_openarm_follower)数据集,由LeRobot工具创建。它包含2个episodes,总计1218帧,帧率为15fps。数据包括机器人的动作(action)和观测状态(observation.state),其中动作和状态数据涵盖左右臂各7个关节及抓手的位姿(pos)、速度(vel)和扭矩(torque),共48维特征。此外,观测部分还提供了多视角图像视频数据,包括front、front2和up三个视角,每个视频分辨率为480x640,3通道,采用h264编码。数据集结构以parquet文件存储,并包含时间戳、帧索引、episode索引等元数据。所有数据均用于训练集(splits: train),旨在支持机器人控制、模仿学习等任务。
This dataset is a bi-arm robot (bi_openarm_follower) dataset for robot learning, created by the LeRobot tool. It contains 2 episodes, totaling 1218 frames, with a frame rate of 15fps. The data includes robot actions (action) and observation states (observation.state), where action and state data cover position (pos), velocity (vel), and torque (torque) for 7 joints and grippers of both arms, resulting in a total of 48-dimensional features. Additionally, the observation part provides multi-view image video data, including front, front2, and up perspectives, each with a resolution of 480x640, 3 channels, encoded in h264. The dataset is stored in parquet file format and includes metadata such as timestamps, frame indices, and episode indices. All data is used for the training set (splits: train), aiming to support tasks like robot control and imitation learning.
