font-size: 16px; text-wrap-mode: wrap; background-color: rgb(255, 255, 255);&quot;&gt;Ace系统的核心在于其超越人类极限的感知与控制能力。为了在高速对决中看清球路，研究人员为它配备了一套精密的视觉系统。整套系统由9台高速摄像头组成，用于精确捕捉球在三维空间中的位置，定位误差控制在3.0mm以内。更具突破性的是，为了解决乒乓球运动中最难处理的“旋转”问题，团队引入了三套基于事件的视觉跟踪系统。这种传感器不像传统相机那样逐帧拍摄画面，而是只记录像素亮度的变化，从而实现了极低的延迟和极高的动态范围。通过这种感知方案，Ace能够实时估算球的角速度，平均误差仅为24.8rad/s。&lt;/p&gt;&lt;div class=&quot;google-auto-placed ap_container&quot;

font-size: 16px; text-wrap-mode: wrap; background-color: rgb(255, 255, 255);&quot;&gt;在控制层面，Ace并没有使用传统的预设程序，而是采用了深度强化学习技术。所有的训练都在高度仿真的模拟环境中完成。为了让AI能从虚拟世界顺利过渡到现实赛场，研究人员采用了一种非对称的“行动者,评论家”架构。在训练时，负责评价表现的“评论家”可以感知球的所有真实状态信息，而负责操作的“行动者”则只能接触到带有噪声的传感器数据。这种训练方式让AI学会了在现实世界不完美的感知条件下做出最优决策。此外，Ace拥有一套庞大的“技能库”，涵盖了上旋球、下旋球等多种击球技巧，它能根据对手的来球情况，在32ms内快速切换并生成最佳的击球轨迹。&lt;/p&gt;&lt;div class=&quot;google-auto-placed ap_container&quot;

font-size: 16px; text-wrap-mode: wrap; background-color: rgb(255, 255, 255);&quot;&gt;Ace还展示了一些令人惊讶的灵活性。在面对擦网球等极难预测的突发状况时，低延迟的感知和控制系统让它能在0.05s内迅速做出反应并成功回击。此外，Ace还掌握了15种不同类型的发球技术。在与精英选手的比赛中，它直接通过发球就拿到了16分，而人类选手通过发球从它身上拿到的分数仅为8分。&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box;

font-size: 16px; text-wrap-mode: wrap; background-color: rgb(255, 255, 255);&quot;&gt;这一研究的成功证明了物理AI智能体在处理复杂的实时交互任务方面具有巨大的潜力。虽然目前Ace在高端战术和针对性策略上仍有提升空间，但它已经展示了AI如何改变人类与物理世界的互动方式。正如参加过1992年奥运会的乒乓球专家Kinjiro Nakamura所言，看到Ace的击球表现，人类会意识到那些看似不可能的接球动作其实是存在可能的。未来，这种融合了高速视觉、强化学习和轻量化硬件的技术架构，有望被应用到自动化制造、服务机器人以及更多需要人机精密协作的领域中。&lt;/p&gt;</description><pubDate>Mon, 30 Mar 2026 15:14:12 +0800</pubDate></item></channel></rss>
