Roboticists at the University of California San Diego have developed an affordable, easy-to-use system to track the location of flexible surgical robots in the human body. The system performs as well as the current state of the art, but is much cheaper. Many current methods also require radiation exposure, while this system does not.

The system was developed by Tania Morimoto, professor of mechanical engineering at UC San Diego's Jacobs School of Engineering, and Ph.D. student Connor Watson. Their findings are published in the April issue of IEEE Robotics and Automation Letters.
