From the main article… “Whether they are based on soft or hard magnetic materials, the magnetization process of most soft robots is coupled with its ,” Ran Zhao, one of the researchers who carried out the study, told Techxplore. “In other words, the robots cannot realize the reconfiguration of functions through programs like traditional robots with control units. This means that magnetic soft robots have a long way to go before they can be applied in real-world settings.”.
