Mumbai eatery delivers pizza using a drone

Apart from that there are technical difficulties like a limited operating radius of 8 km after which the batteries go dry, he said, adding proper infrastructure like having charging stations can help.

Even though the four-rotor version drone had a limited carrying capacity, he said the payload capacity can be increased to up to 8 kg in case of a an eight-rotor drone.

Beyond the strategic applications, the drones are increasingly being used for a cross variety of purposes especially the ones centred around getting aerial imagery like getting videos at weddings, political rallies etc.

At present, Rajani said, the drones are being operated manually but added in future, we can have drones fly by themselves on predetermined flight paths made using GPS data.

During the test-flight, the drone picked up a box containing the pizza but bigger drones will be easily able to lift the special flask box which can protect the pizza from the atmospheric elements, he said.
