机器人也许比人类更便宜，但似乎他们仍然需要提高自己的交际能力。上周，硅谷斯坦福购物中心（Stanford Shopping Center）的一名机器人保安在执勤时撞倒了一名蹒跚学步的儿童，然后很明显他继续开车。当地新闻频道ABC7的一篇报道说，机器人击中了16个月大的哈文·程，把他打倒在地。

郑并没有受到严重伤害，但我们仍将此归为违反了艾萨克·阿西莫夫的机器人第一定律：“机器人不能伤害人类，也不能因为不作为而允许人类受到伤害。”以下是ABC7的故事：

It amuses shoppers of all ages, but last Thursday, 16-month-old Harwin Cheng had a frightening collision with the robot. "The robot hit my son's head and he fell down facing down on the floor and the robot did not stop and it kept moving forward," Harwin's mom Tiffany Teng said.

Harwin's parents say the robot ran over his right foot, causing it to swell, but luckily the child didn't suffer any broken bones. Harwin also got a scrape on his leg from the incident. "He was crying like crazy and he never cries. He seldom cries," Teng said.

被质疑的机器人是Knightscope K5，一种5英尺、300磅重的机器，去年开始在商场试用。这个机器人在轮子上滚动，并使用一系列传感器和摄像头来监控它的环境。人类保安可以将机器人引导到特定的地点，查看发生了什么，机器人应该向中央警卫站报告任何异常活动。机器人的创造者形容它拥有一种结合了“先进技术”的“指挥性物理存在”

k5的**成本仅为每小时6.25美元，低于最低工资

目前尚不清楚郑文到底发生了什么事，奈特斯普还没有就此事发表任何声明，也没有回应来自边缘的评论要求。虽然与郑的事件似乎很小，但骑士镜显然不希望再发生这样的事情。尽管K5一小时只需6.25美元的工资（低于最低工资），但没有人会**一个碰到孩子的机器人。

美国东部时间7月14日凌晨3时40分更新：奈特斯普就事件发表声明，形容这是一场“怪诞事故”，并强调K5在没有类似事故的情况下行驶了25000多英里。公司还表示，多次与程某联系，没有回应，并邀请家属到奈特斯普总部，这样团队成员就可以“当面恭敬道歉，向此事学习”

该公司还提供了传感器记录的事件描述：

A K5 Autonomous Data Machine (Machine Identification Number 13) was patrolling at a local shopping center when, at approximately 2:39pm PDT, a child left the vicinity of his guardians and began running towards the machine. The machine veered to the left to avoid the child, but the child ran backwards directly into the front quarter of the machine, at which point the machine stopped and the child fell on the ground. The machine’s sensors registered no vibration alert and the machine motors did not fault as they would when encountering an obstacle. Once the guardians retrieved the child and the path was clear, the machine resumed patrolling. The entire incident lasted a few seconds and a scrape on the child’s leg and a bruise with minor swelling were reported.

“我们首先想到的是家人，我们很庆幸没有严重受伤，”Knightscope首席执行官William Santana Li说我们的首要使命是为公众的整体安全服务，我们非常认真地对待任何可能危及这一使命的情况。”

我们能造一台有意识的电脑吗？
