At the same time, within 100-1000m behind the accident site, the robot can be controlled to move to the front of the accident and stand on the roadway. A warning light and a warning sound are emitted. Even if a vehicle hits the robot, no serious vehicle damage will occur. Letting the robot block the vehicle at close range is actually forcing the vehicle to slow down to prevent it from hitting the vehicle that has already been involved in a car accident, causing serious casualties. It is a second-best means of avoiding or reducing casualties.

Moreover, because the robot is always patrolling along the highway, it can quickly arrive at the scene of the accident. On the one hand, it can block the vehicle that is about to hit the car in the accident to avoid serious casualties, and on the other hand, it can remind the rear vehicles at medium and long distances to slow down. . In this way, multiple vehicle collisions can be avoided to a large extent, and the probability of large-scale accidents can be reduced.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes.
