Jun Shintake, an engineering professor at Japan’s University of Electro-Communications, thinks that edible drones can help save lives.

Shintake is working with researchers from Switzerland to create edible robots for different types of situations. Their new design is a flying drone with wings made of rice crackers.

The prototype is about 70 centimeters wide and the rice cracker wings are connected together by gelatin. The edible parts of the drone contain about 300 calories. The drone can also carry about 80 grams of water.

The researchers think that a drone like this can quickly deliver emergency food to people in remote places.

Currently, about 50% of the drone is edible. The team of researchers was to increase this to around 75%, and maybe one day the whole drone will be edible.

The team is improving the drone’s durability and how far it can fly. Then, they want to commercialize it.

Shintake also thinks that edible robots might be helpful in factories. One of his teams has made a robotic arm from gelatin and other edible material. The robotic arm moves like a human finger and is strong like rubber.

Shintake says that it’s safer to use edible materials for robots in factories that make food. It lowers the chance of dangerous material, like metal, getting into the food.
