Scientists from the UK have introduced what they say is the world’s first mini-robot for 3D ultrasound diagnostics of the intestines. The design is based on the shape of an oloid: this allows the robot to roll over curved parts of the bowel, with movement controlled by a magnetic field from outside.
The device is equipped with a high-frequency ultrasound system that can produce detailed three-dimensional images of tissue without the need to take a biopsy.
The technology has already been successfully tested on intestinal models: the robot navigated accurately, identified pathological changes, and generated “virtual biopsies” in real time. This means that doctors may be able to make a diagnosis and even begin treatment in a single visit—without pain, without anesthesia, and without the anxiety of waiting.
Clinical trials on people are planned for 2026. The approach aims to support earlier detection of disease, which can make treatment more effective.
