Naturally, Floreano decided to make edible robots after hearing this, and RoboFood was born. But how does RoboFood work exactly? Essentially, the researchers are trying to create a library, or pantry if you will, of smart edible materials that can be used to construct robots and robotic foods. This goal includes creating electronic components like sensors and mechanical structures that can ultimately be consumed.
While the idea of edible robots may seem far-fetched, the team has already made impressive progress on the goal. So far, the RoboFood researchers have learned that some starch and tannins can replace glue when building a robot. They also found that gelatin, rice cookies, and other substances can be used in place of important structural materials like rubber and foam.
