iRobot 发布 Roomba

2002 年，iRobot 推出了一台圆盘形的扫地机器人 Roomba。它没有面孔、不会说话、没有地图，工作方式简单得近乎原始：碰到障碍就转弯，沿螺旋路径把房间覆盖一遍。但在那个「机器人还只存在于实验室和工厂」的年代，它做出了一个所有人都低估的决定——把机器人卖进普通家庭。

Roomba 的背后没有炫目的 AI。它的导航靠的是碰撞传感器和一套笨拙但有效的规则：哪里撞了就换方向，转几圈就换区域。这种策略在今天看来粗糙，却在当时恰到好处——它不需要昂贵的传感器，不需要复杂的算法，成本压到了普通家电的水平。而「足够好用」这件事，比「看起来聪明」更重要。

它的成功改变了整个行业对消费机器人的想象。Roomba 发布后迅速成为爆款，扫地机器人从新奇玩物变成家庭常备电器，iRobot 开创了一个数十亿美元的新品类。更深远的是，这些机器在家里日复一日地运行，积累了海量的真实家庭数据——房间形状、家具位置、使用习惯——这些成为后续导航技术与家用机器人演进难得的实践土壤。

Roomba 还示范了一条重要的产品哲学：技术不必等人形机器人成熟，先在一个狭窄但真实的需求上做到可靠，就能创造价值。后来的家用机器人、服务机器人，或多或少都沿用了这条「先落地、再进化」的路线。

回看 Roomba，它的历史意义不在技术突破，而在市场教育。它让「机器人走进千家万户」从一句口号变成现实，也让消费机器人这条赛道真正跑了起来。当今天人形机器人讨论得热火朝天时，那个 2002 年在地板上转圈的小圆盘，是这一切最早的序章。

In 2002 iRobot launched Roomba, a round robot vacuum. It had no face, no voice, no map, and worked almost primitively: turn on collision, cover the room in a spiral path. Yet in an era when robots lived in labs and factories, it made a decision everyone underestimated—selling robots into ordinary homes.

There was no dazzling AI behind Roomba. Navigation relied on collision sensors and a clumsy-but-effective rule set: change direction when you bump, change zone after a few circles. Crude by today's standards, but exactly right then—no expensive sensors, no complex algorithms, cost held at ordinary-appliance level. And "good enough" matters more than "looks smart".

Its success reshaped the industry's imagination of consumer robots. Roomba became a hit overnight; robot vacuums went from novelty to common appliance, and iRobot created a multi-billion-dollar category. Deeper still, these machines ran in homes day after day, accumulating real household data—room shapes, furniture positions, usage habits—practical soil for later navigation tech and home-robot evolution.

Roomba also demonstrated a product philosophy: technology need not wait for humanoids; deliver reliability in one narrow but real need first, and value follows. Later home and service robots have more or less followed this "ship, then evolve" route.

Looking back, Roomba's historical significance lies not in technical breakthroughs but in market education. It turned "robots entering every home" from slogan to reality and got the consumer-robot track truly running. When humanoid robots dominate today's discussion, that little disc spinning on living-room floors in 2002 is the earliest prelude.
