“…The average value of maximum load at breaking point is 297 N with standard deviation 46 N. Samples started to fail reaching average extension of 28 mm with standard deviation 2 mm. This number fulfils the previously presented required force of 30 N that can be applied by an index finger of adults between 22 and 30 years old [31]. Under a load of 30 N, the deflection is smaller than 1.5 cm, which is smaller than the 35 mm that separate the grid from the tip of the rotating propeller.…”

“…To validate the safety of the grid while a finger is pushed on the grid, an experiment with an artificial finger was performed. Of interest is how much force is required to deflect the grid 35 mm (the distance to the propeller tip) and how that compares with the force applied by an adult of 22 to 30 years of age when catching the vehicle, which is 30 N [31].…”

Delivery drones used by logistics companies today are equipped with unshielded propellers, which represent a major hurdle for in-hand parcel delivery. The exposed propeller blades are hazardous to unsuspecting bystanders, pets, and untrained users. One solution to provide safety is to enclose a drone with an all-encompassing protective cage. However, the structures of existing cage designs have low density in order to minimize obstruction of propeller airflow, so as to not decrease efficiency. The relatively large openings in the cage do not protect hands and fingers from fast rotating propellers. Here we describe a novel approach to safety and aerodynamic efficiency by means of a high-density cage and morphing arms loosely inspired by the box turtle. The drone cage is made of a dense and lightweight grid. When flying in proximity of humans, the arms and propellers are retracted and fully sealed within the cage, thus making the drone safe and also reducing the total footprint. When flying at cruising altitude far from people and objects, the arms and propellers extend out of the protective grid, thus increasing aerodynamic efficiency by more than 20%.
