Description

Automatic hand signal system{AUTOMATIC HAND SIGNAL SYSTEM}

The present invention relates to an automatic hand signal system, and particularly to a mannequin-type automatic hand signal system that is installed on a road under work and automatically sends a hand signal to a running vehicle.

In general, when carrying out various constructions or works such as road surface repair work, painting work, and guardrail installation on roads such as national roads, local roads, and highways, vehicles driving adjacent to the work area may hit workers or facilities in the work area. To prevent collisions, assistant workers are assigned far in advance of the work area and wave light sticks to inform drivers of the current road conditions in advance.

However, there are situations where a running vehicle may enter a work zone due to the driver's drowsy driving or speeding. In particular, it is often reported that a driver fails to spot an auxiliary worker on the road, resulting in a fatal accident.

To prevent such accidents, an automatic hand signal device using a mannequin-type robot rather than an auxiliary worker was proposed. The conventional automatic hand signal device prepares a mannequin robot with the appearance of a worker, installs a light stick on the robot arm, and automatically drives the light stick to shake to send a hand signal to drivers on the road.
