Researchers at the Massachusetts Institute of Technology are developing tiny robots powered by magnets that can be used inside the human body as part of a medical procedure. The team designs each tiny robot separately, depending on its function, then magnetic microparticles are added during the 3D printing process. A robotic arm is attached to an artificial kidney in this image released by Boston Children's Hospital.

The team said some robots can be made to move with the wave of a magnet, while others will require a magnetised chamber to function.
