Robotic cake has batteries you can eat – and they even taste good
Adding new meaning to the term "fusion cuisine," an international team of adventurous researchers has united robot science and gastronomy to create an elaborate multi-tiered cake with edible components and the world's first edible rechargeable battery. (Well, it's rechargeable until you eat it.)
Researchers from Switzerland's École Polytechnique Fédérale de Lausanne (EPFL) and the Italian Institute of Technology (IIT) have formed an unlikely collaboration team with pastry chefs and food scientists to create the RoboCake, currently on show at Osaka's Expo 2025. Sitting atop the elaborate piece are edible robotic bears, which are reported to taste like pomegranate gummies, which have an internal pneumatic system that provides movement for their limbs and head. “Our challenge was to find the best way to showcase the innovations of our two partners, EPFL and IIT, by adding what we do best: indulgence," said Julien Boutonnet, a senior lecturer at Swiss hospitality school EHL and recipient of the Meilleur Ouvrier de France (MOF) award for pastry and candymaking.
