Bad news for the delivery guys: you might have to start flunking about finding a new job very soon because delivery men bringing items to home may become a thing of the past one day. Well, I may have exaggerated the situation a little bit but what I’m going to tell you next is dead true. A robot that can drive itself on sidewalks to make door-to-door deliveries is going to be tried out in London and some as-yet-undisclosed U.S. cities in the coming months. Here is a picture of the small, black-and-white, slightly rounded machine on six wheels, a brand-new product of the London-based developer, Starship Technologies. It can blend in with the pedestrian traffic. Lightweight, it can only carry a small amount in its top compartment—two grocery bags or small packages up to nine kilograms. The company’s chief executive officer, who also co-founded Skype, said the unnamed robot is practical, safe and environmentally friendly.
    A user would place an order online, as what people do right now, but instead of getting the delivery by somebody coming up to and knocking on your door, you would get it by a robot. The electric rover isn’t made for long distances. Moving at 6.5 kilometers per hour, which is 4 miles per hour, it can travel up to 5 kilometers, and from a local store or retail outlet it can complete deliveries within a half hour. An advantage for customers is that we can use a smartphone app to decide when we want deliveries to arrive. You know, we call up the delivery using our smartphone, and then the robot gets loaded with our parcel and drives to our doorstep. Once the robot gets moving by using a navigation system that also helps it avoid pedestrians, the customer can use the smartphone app to track it and, upon arrival, unlock the compartment.
    You must be thinking about thieves, aren’t you? Actually, a lot of thought has been put into protecting the robot from thievery. The robot has nine cameras and GPS. There’s an operator who can actually talk to the people around the robot, so there’s this loudspeaker in the robot. I just can’t wait to make an order and have it delivered to my doorstep by a robot. I mean, anything would be OK I just want more contact with the robot than the package itself.
22. What does the speaker say about the delivery in the future?
23. What do we learn about the robot from the lecture?
24. How long can the robot travel for one time?
25. What has been done to the robot to protect it from thieves?
