These tiny robotic tentacles could travel into the lungs to treat cancer

Scientists have developed tiny robotic tentacles that travel into the lungs to detect and treat cancer. The device is just 2.4 mm in diameter and ultra-soft.  It’s sent to the periphery of the lungs from the end of a bronchoscope — a thin tube with a light and camera. During the journey, magnets adapt the robot’s shape to the body’s anatomy. As it moves, both its form and position and form are fed back to a clinician. After reaching its destination, an embedded laser fibre can deliver localised treatment. The robot was developed at the University of Leeds’ STORM lab, which…
