Researchers at the Wyss Institute for Biologically Inspired Engineering and the Harvard John A Paulson School of Engineering and Applied Sciences have developed robots which are able to move within a magnetic field without using batteries or power cables, according to an article in Science Robotics. By changing the frequency of the external magnetic field, they were able to induce each SMA coil to contract independently from the others. The researchers used two different types of robotic arms that can be controlled by electrical signals from electrodes implanted on their bodies. The team built several sizes of robot to demonstrate ease of scalability.
