Volkswagen built a robot that can find your electric car in a parking lot and charge it

Finding that one free charging spot in a parking garage can be a chore, but if Volkswagen's new project catches on, the charging spot might come to you instead. 

On Thursday, the company announced a concept for a mobile charging robot that comes to electric cars and charges them on its own. 

The robot would be able to communicate with the car, open the charging socket flap and plug in with no human interaction. It's fitted with cameras, laser scanners and ultrasonic sensor, which would allow it to move freely and go around obstacles.
