Muscles for soft robots inspired by nature: Hydrogel actuators with improved performance

Robots made of metal and other solid materials are already widely used in industry. But they are too rigid and cumbersome for fine-motor activities and interaction with people, such as in nursing or medicine. Intensive research is therefore already being carried out into robots made of soft materials: inspiration from nature, such as jellyfish, earthworms, fish or the human body should enable "soft robots" that can move flexibly and adapt to their environment.
