Join us as we explore how a new vine-like soft magnetic robot is shaping up to revolutionize medical diagnosis and treatment.
Explore how Professor Pietro Valdastri’s vine-like magnetic robots are transforming cancer diagnosis and treatment by navigating the most difficult-to-reach areas of the human body., a robotics and autonomous systems leader at the University of Leeds. We explored his team’s cutting-edge work on soft magnetic robots that mimic vine plants.
“Instead of having a mechanism inside the robot to steer and move the tip left, right, up, or down, we use magnetic fields,” he explains. “This allows us to reduce the robot’s size because we don’t need internal cables or actuators,” he added.Valdastri explained that the robots work via a combination of pneumatic pressure, which powers the robot’s growth, and magnetic particles embedded in its skin. This makes the robot’s movement both gentle and precise.
However, the magnetic vine robot makes reaching these hard-to-access areas feasible. “We hope to get to the periphery of the lungs, and there deploy treatment or take biopsies,” says Valdastri. Current medical technologies also fail in the small intestine. “Reaching the small intestine with traditional tools is very difficult and often requires full sedation,” he says. This technology could allow us to get there in a much less invasive way,” he told IE.Despite its immense potential, the vine-inspired robot still needs to overcome technical challenges before it can be widely adopted.
