The technology stems from a 2019 prototype inspired by a lionfish, utilizing a hydraulic fluid system, or “robot blood,” that powers devices by circulating energy. This system has been refined for higher battery capacity and power density, supporting the new robotic forms in more complex environments.
Professor Rob Shepherd explains that the jellyfish’s enhanced capacity allows it to operate longer than its aquatic predecessor, while the worm, their first terrestrial model, demonstrates greater freedom of movement without needing a rigid structure.
