Edible Robots: RoboCake Takes Center Stage at Expo 2025

The EU-funded RoboFood project unveiled its groundbreaking creation: RoboCake, an edible robotic wedding cake! Developed by EPFL and IIT researchers in collaboration with pastry chefs, this cake features two adorable, edible robotic teddy bears animated by an internal pneumatic system. Even more innovative, IIT created edible rechargeable batteries made from vitamin B2, quercetin, activated carbon, and chocolate, powering the cake's LED candles. This interdisciplinary marvel not only offers a unique culinary experience but also addresses electronic waste and food waste issues, with applications in emergency nutrition and healthcare.
