The swarm of robots, collectively called Avert, are the creation of a European consortium led by the Democritus University of Thrace in Greece. To use the 'Autonomous Multi-Robot System for Vehicle Extraction and Transportation' (Avert) system, a computer model will choose a vehicle to be moved. The Avert system then works by sending a deployment unit (bottom right) to scan the area and identify potential obstacles. Bogies deploy from this unit and are tracked to a target vehicle, where they dock onto the wheels and lift the car.
