It is a nightmare situation. You are on an bold mountain hike while you get misplaced, injured or stranded. The excellent news is assistance is lastly on the best way, however the unhealthy information is it is going to take time to achieve you and also you’re out of meals. That is when a buzzing drone comes flying in for a touchdown. Not solely do you get the snacks, drugs or water it is carrying, you may eat the wings to tide you over till the rescue workforce arrives.

This situation may grow to be actual. A workforce with the Swiss Federal Institute of Know-how, Lausanne (EPFL) has developed a prototype edible drone. The munchable machine is a part of a broader venture referred to as RoboFood. RoboFood is about investigating edible robots for people and animals in addition to meals that behave like robots.

The team published its work online with the title “In the direction of edible drones for rescue missions: design and flight of dietary wings.” The examine is tackling the issue of getting industrial drones to hold sufficient of a payload to assist individuals in emergency conditions.

The design makes use of some familiar-looking airplane-like elements, however the large distinction is that the fastened wing is created from rice muffins and gelatin that collectively pack 300 energy. IEEE Spectrum spoke with lead author Bokeon Kwak who mentioned the drone “tastes like a crunchy rice crisp cookie with a bit of contact of uncooked gelatin.” Should you’re stranded and hungry, it will most likely be scrumptious.   

The edible drone took a profitable check flight.


To make the wings, the researchers trimmed up spherical rice muffins utilizing a laser cutter and glued them along with gelatin to create a wing construction that would maintain as much as flight. The rice is robust, however light-weight and nonetheless moderately nutritious. The drone could be a one-way proposition, however the partially edible nature means there would not be lots of particles left behind.

The concept of edible drones has been kicking round for years. We met a chocolate quadcopter again in 2014 and a UK aerospace firm talked up an edible drone called Pouncer in 2017. It appears Pouncer hasn’t made it into manufacturing, however the common idea is alive and effectively with the rice-cake-wing drone.

The edible-drone workforce intends to analyze methods to make the drone extra nutritious and see if it may add extra edible elements to the design. It doesn’t matter what you consider rice muffins as a meals, in a tricky scenario, they’d be like manna from heaven.
