Eye of caring / Drone for blind service

The drone is designed to help the blind cross the road more safely.These drones are public drones. They stop on the dock to recharge when no blind people pass through the crossroad.When blind people come to the crossroad,the drones can identify them automatically though the equipment on the crutches of blind people.Two drones can follow a blind man and project a light beam for the blind man.The part of the road with light beam is a special route for the blind people. It also can remind the passerby that a blind man is crossing the road.When the blind man deviates from the route, the equipment on the crutches can remind the blind by vibration.
