After years of hard work, Researchers at Phillips Innovative Technologies in Hamburg, Germany succeed to incorporate robotics into delicate medical procedures.

They come up with a tiny device that could inject drugs into person’s eye or bend to operate on hard-to-reach areas. Researchers have created a way to manipulate each robot in a swarm individually and assign them specific tasks using magnetic fields. The scientists presented their findings on Feb. 15th in the Journal Science Robotics.

Scientists wants to use this robotic swarm to deliver cancer-killing radioactive seeds specifically to tumors within the body. Treating cancer this way could spare healthy tissue and reduce harmful side effects. It could also be used to create medical implants that change over the time as a person heals.
