Now, retail giants including Amazon, Alibaba, and Wal-Mart are testing drone delivery services, but they all have a very important problem that has not been solved, that is, how to prevent them from delivering drones. People or other aircraft pose a hazard. After all, after the drones are popularized, there will be many such aircraft in the air, it is difficult to prevent them from colliding, and it may also bring danger to people on the ground. It seems that Google has found a solution - at least it has proposed a patent on the collision of drones with humans. Patent documents show that drones warn humans and drones at a safe distance through low-tech voice during delivery. However, Google may overestimate the logic of human beings. As you can see from the picture below, the local people have received the warning message from the drone to make a decision to retreat, but we know that the reality is not completely effect. Since the patent document does not provide information about the content of the alarm, it may be just a sharp, harsh sound like a normal alarm. If this is the case, then it is definitely not acceptable. Perhaps Google's best choice is to give a warm reminder, and then gradually increase the warning. In addition, the patent documents show that the system will also be equipped with indicator lights, red for the back, yellow for the unloading, and green for picking up as soon as possible. Perhaps the easiest way to do this is to find the best solution today.
