Renee Zhao, a Stanford mechanical engineering professor, is at the forefront of robotic surgery with her innovative millibots. These magnet-controlled, millimeter-scale soft robots aim to navigate the bloodstream for medical repairs like removing clots and treating brain aneurysms. Zhao discusses the exciting potential of soft robotics, drawing inspiration from octopuses, and the challenges of miniaturization. She also highlights the balance needed between design and functionality to revolutionize healthcare through advanced surgical techniques.
