Researchers Control Soft Robots Using Magnetic Fields, North Carolina State University Study Reveals

A team of engineering researchers has made a fundamental advance in controlling so-called soft robots, using magnetic fields to remotely manipulate microparticle chains embedded in soft robotic devices. The researchers have already created several devices that make use of the new technique.

“By putting these self-assembling chains into soft robots, we are able to have them perform more complex functions while still retaining relatively simple designs,” says Joe Tracy, an associate professor of materials science and engineering at North Carolina State University and corresponding author of a paper on the work. “Possible applications for these devices range from remotely triggered pumps for drug delivery to the development of remotely deployable structures.”
