Story summary

EPFL researchers have developed the first ingestible robot with a battery, valve, and actuator.
The device is designed to deliver nutrition or medication to elusive animals, such as wild boars.
The gelatin and wax battery generates CO2 gas when citric acid and baking soda mix.
The actuator wiggles to mimic prey, potentially aiding vaccine delivery.
The work is part of the EU-funded RoboFood project, which aims for environmentally sustainable robotics.
