Dubai police will be able to respond to an incident anywhere in the United Arab Emirates city within a minute, thanks to a network of pre-positioned drone bases. The quadcopters, supplied by Israeli company Airobotics, will operate from base stations during the Expo 2020 event starting in October this year, an exhibition said to be the third largest event in the world after the Olympics and the World Cup. The drones will reduce police response time from 4.4 minutes to 1 minute according to a tweet from Dubai's ruler Sheikh Mohammed bin Rashid Al Maktoum. Each base has a sliding roof that allows the drones to enter and exit. The drones can fly pre-programmed patrols, or be dispatched to a specific location, allowing an operator at police headquarters to inspect the scene, or follow a suspicious individual or vehicle and pass data to other police units.
