A sandal that will protect women from attackers?

These students in Moradabad are working towards making the world safer for women. Two engineering students have created a special sandal that can shock an attacker, signal a drone for help and take a picture of the attacker. The drone will also be connected to a nearby police station, which can alert them of the victim's location. The students say that their college plans to patent it and provide some girls with a prototype to use it.
