全球首个！这个机器人100%可食用，连电池都能吃

Core Viewpoint - Researchers from EPFL have developed a fully edible robot, marking a significant advancement in the field of soft robotics, with all components being 100% consumable [4][7]. Group 1: Edible Robot Components - The robot's battery is made from gelatin and wax, utilizing a chemical reaction to store energy, with food-grade materials like citric acid and baking soda [9]. - The actuator operates on a pneumatic system, where carbon dioxide generated from the battery drives the movement [11]. - A novel edible valve based on the "snap-buckling" principle allows for controlled gas release, enabling the actuator to function effectively [12][13]. Group 2: Potential Applications - The primary application proposed for this edible robot is to deliver nutrients or medication to hard-to-reach wildlife, such as wild boars, by mimicking movement to attract them [17][20]. - The robot's design can be adjusted to target various animals by modifying its size, movement characteristics, and sensory attributes [21]. Group 3: Broader Implications - The project emphasizes environmental sustainability, as the edible components are biodegradable, aligning with future applications of large-scale robotic systems in natural settings [24]. - The research is part of the EU-funded RoboFood project, exploring further developments in edible robotics [25].
