Soft Robot Grows Like a Plant to Travel Through Tight Spaces

At the University of Minnesota, researchers have developed a soft robotic system that can ‘grow’ like a plant. The mechanism allows it to travel through difficult-to-access areas, such as the tortuous gastrointestinal tract or vasculature. The system works by extruding a liquid through an opening in the device, and at the same time a photopoly (Read more...)
