15.Imagine entering a very large building and you have no idea how to get to the office you are looking for.But then,as you're standing there,a nearly silent balloon floats (飘) over to you and speaks to you.It asks you where you want to go.You tell it,and then it simply says"follow me"like a child's game,and begins to float off in the direction of your destination.It keeps going,as you follow,leading you to where you want to go.
The guide works itself,without any help from any human being.It says hello to people as they arrive in the building,speaks to them,processes their requests and then guides them to the destination.
The balloon has two tiny fans to help keep it floating and to provide just a touch of lift.Onboard is a wireless (无线的) receiver for receiving directions from a computer that directs the fans and sensors (传感器) that let it know where objects are around it.
The idea of such a simple robot is one that has been on the minds of scientists for years,and has been mentioned in novels many times.Today the iPhone does something similar but has to be connected to the Internet which is sometimes difficult.This is why this little balloon might be the wave of the future-because it is so much easier to follow!
