Although the current navigation system is very convenient, there are still many people who have no sense of direction and cannot understand the navigation of the map. For those out-of-town travelers who are unwilling to communicate with other people, when they are lost, if they cannot understand the mobile phone map and cannot communicate with others, it will make them difficult to move.
Therefore, robots or drones that guide the way can be set up on the streets. The use of this way guide robot can be free. Appropriate fees can also be charged, depending on the owner of the guidance robot, and the fees charged can be used for robot maintenance. Out-of-town travelers can place orders through their mobile phones and enter their destinations on the mobile phones. After the guidance robot receives the commands, it will automatically recommend the optimal route. The travelers only need to follow the robot to reach the destination. When the traveler arrives at the destination, the robot or drone can automatically return. Using this kind of robot is also conducive to protecting the safety of travelers. It should be noted that the forward speed of this kind of road-guided robot or drone can be adapted to the user, and its power can ensure that it returns to the place of departure.
