Researchers at the Swiss Federal Institute of Technology Lausanne (EPFL) have developed an unmanned aerial vehicle with edible parts for emergencies. This is reported by IEEE Spectrum.
Drones can potentially be very useful in disaster scenarios, delivering food and water to those in need. But most transport UAVs can only carry about 30 percent of their weight. However, scientists believe they have found a way out of this situation.
At the IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS ) held last week in Kyoto, researchers presented a paper describing a drone that can increase the payload food from 30 to 50% of its mass.
In particular, the wings of the experimental drone model were made from rice cakes, which are quite high in calories. Instead of glue for the wings, gelatin was used. The edible wings have been coated with plastic so that they won't break down in a humid environment.
In the future, the inventors plan to add more edible elements, as well as find a way to carry a payload (such as water) in an edible container.
