Hitchhiking delivery drones could carry packages long distances by perching on the roofs of buses

Delivery drones could hitch a ride by landing on public transport to deliver to far away locations. Most prototype delivery drones can currently travel around 12 miles to make a delivery before their battery fails. This range could be extended by about four-and-half times if the agile machines landed on the roofs of buses or trams to piggyback in the right direction, finds study. Shushman Choudhury, who led the research at Stanford University in California told The New Scientist: 'We already have this existing, generally decent infrastructure for most good cities and we're just benefiting from that. 'You could now service deliveries over a city while having far fewer depots.'
