美国一家公司研发出送快递的机器人。这种机器人体型小、安全准确、无污染。它们可搬运两个购物袋的货物,在5到30分钟内将物品送到指定客户手中。货物送达后,客户通过手机解锁安全箱,取走自己的物品。美中不足的是,这种机器人不适合路况复杂的远距离送货。 A U.S. company developed a robot that delivers couriers. This robot is small, safe and accurate, pollution-free. They can carry two shopping bags of goods, in 5 to 30 minutes to the designated items in the hands of customers. After the delivery of the goods, the customer unlocks the safety box through his mobile phone and takes away his belongings. The only drawback is that this robot is not suitable for long-distance delivery complex road conditions.
