The delivery drones are fully electric, environmentally friendly, and are equipped with a shielded design that protects it from hazards and mid-air collisions. Advanced motion sensors are used to detect obstacles both in-air and near the ground, which helps them with vertical takeoffs and landings. Since the project’s initial announcement, major advances have been made to ensure the drones are as safe and efficient as possible. The cameras and obstacle sensors are now sensitive enough to detect thin structures like clotheslines and wires. Tests have been occurring for a while now near its depot location in Cambridge, England. Additionally, the company has partnered with NASA itself to perfect its air-traffic control systems for maximum stability. With all these exciting announcements, however, it’s important to be realistic about how this new system is likely to roll out. That’s not to say things will stay this way. Select cities may pilot the program, but as popularity and infrastructure grow, you can expect Prime Air to expand to more cities in the coming year.
