And as it turns out, even robots have had trouble getting by on sandy terrain—until now, that is. Researcher Baptiste Darbois Texier and his team from the University of Santiago in Chile have been developing a 3D printed robot that is suited for moving through sand and other granular materials. The robot, which measures just 12 centimeters in length, is made up of a plastic 3D printed head and a helical tail. A tiny battery and motor […]
