When it comes to surgical robots, most people assume they are giant machines that handle surgical instruments. In reality, microrobots that can move across soft, uneven surfaces can come in handy for minimally invasive surgeries. Take this 4.4mm long robot for instance: it can cut tissue and release drugs. According to the researchers, it is possible to shrink it down to 1.5mm.

This robot can grip and store biological tissues. It can also heat to perform hyperthermia treatments. As the researchers explain, they use magnetic fields to move these robots across unstructured terrains. With this approach, it is possible to perform lifesaving procedures that pose less risk to patients and allow for faster recovery.
