[视频]科学家利用强化学习培训四足机器人守门员_我的网站

A |     (ECNS) -- China had 5.29 million licensed (assistant) physicians by the end of 2025, surpassing the target set in the 14th Five-Year (2021-2025) Plan, the National Health Commission announced on Wednesday, commemorating the ninth Chinese Doctors’ Day.    The medical workforce has also grown in quality, with the proportion of doctors holding graduate degrees, bachelor’s degrees, and senior professional titles all increasing compared with 2012.    In 2025, the total number of medical consultations in China exceeded 10.6 billion. These advancements have helped bringing key health indicators for Chinese residents to their best levels in history, placing the country among the top ranks of middle-to-high-income nations with populations exceeding 100 million.    (By Intern Lin Qiaochu, Zhang Dongfang)                    。    使用四足动物的足球守门是一个具有挑战性的问题，它将高度动态的运动与精确和快速的非抓握物体（球）操纵相结合。机器人需要在很短的时间内（通常不到一秒）使用动态运动机动对潜在的飞行球做出反应并拦截。

B | 在本论文中，我们建议使用分层无模型 RL 框架来解决这个问题。实际上，机器人需要锁定足球并在不到一秒钟的时间内自行移动以阻挡球。机器人的参数在模拟器中定义，Mini Cheetah 依靠三个动作——回避、俯冲和跳跃——通过确定运动时的轨迹来阻止足球进门。
