硬件不是问题,理解才是门槛:为什么机器人还没走进你家
锦秋集· 2025-09-29 13:40
为什么机器人还没走进你家? 在过去十年里,我们见证了人工智能写诗作画、回答问题、甚至通过考试。但当这些"聪明大脑"让人 惊叹时,机器人却依然停留在实验室和展厅里:它们会在视频中完成惊艳的动作,却很难在你厨房里帮 忙洗碗,或者替你客厅里收拾好一地的玩具。 很多人直觉上以为,这是因为硬件不够强:机械手还不够灵巧,传感器还不够精密,马达还不够迅捷。 但事实是, 硬件的发展速度远快于软件,真正的瓶颈在于——机器人无法像人类一样理解和预测物理 世界。硬件不是问题,理解才是门槛 。 这背后涉及一个核心问题:当机器人伸手去触碰一个杯子、一块布料或一包薯片时,它能否在动作发生 之前,预判出会发生什么?会不会打滑?会不会被压碎?能否保持稳定?对人类来说,这些判断几乎是 下意识的,但 对机器人而言,却是需要复杂建模和计算的巨大挑战 。 近期发表在 Science Robotics 的一篇综述文章,正是聚焦于这一关键难题。由加州大学圣地亚哥分 校、MIT、斯坦福和谷歌等机构的顶尖学者联合撰写,文章系统梳理了"基于学习的动力学模型"——一 种让机器人能够从感知数据中直接学习"世界规则"的方法。 · 相比传统的解析物理模型,这种方法或 ...
