Purdue University researchers have developed a method to use magnetic fields to independently control individual microrobots operating within groups.
The design allows for each microbot to work independently while operating in groups, similar to how ants work. Until now, it was generally only possible to control groups of microbots to move generally in unison, said David Cappelleri, an assistant professor of mechanical engineering at Purdue.
