Researchers at the Science and Technologies Of Robotics in Medicine (STORM) Lab, based at the University of Leeds, have developed a small magnetic robot designed to perform non-invasive “virtual biopsies.” This technology has the potential to support earlier and more accurate detection of cancers in the gastrointestinal tract.
The robot, detailed in a recent publication in Science Robotics, features an oloid shape that allows it to navigate smoothly through the body’s internal pathways. By using an external magnetic field for control, the device is capable of capturing detailed, high-resolution ultrasound images without requiring tissue samples. The design and approach aim to reduce the need for invasive procedures such as traditional biopsies.
Professor Pietro Valdastri, Director of STORM Lab UK, noted: “The oloid robot offers a new approach to imaging the gastrointestinal tract. Our research is focused on improving accessibility and safety in diagnostic methods, and this development represents a step toward that goal.”
The robot has been evaluated for its ability to support endoscopic procedures and may have applications in improving patient outcomes in a range of diagnostic contexts.
