Drone with claws

The researchers used the results of their previous research to develop the claws, in which they used sensors to study the movements of sparrow parrots, and found that, whatever surface they landed on, the parrots always performed the same manoeuvre before landing. As drones are much larger than parrots, the researchers finally chose the peregrine falcon’s claws, which they 3D-printed and used motors and dampers to reproduce the movement of the muscles and tendons.

Drone delivery starts in another US city

Pea Ridge, Arkansas, will be home to the first commercial drone home delivery service in the United States, launched by Zipline. Although customers will be able to choose from thousands of products, they will be limited mainly to health and wellness products such as over-the-counter allergy medicines, bandages and ibuprofen tablets. The service will only be available within a 50-mile radius.
