UC San Diego mechanical engineering professor Michael Tolley and other UC San Diego engineers developed a soft robot with four 3D printed legs: it's the first of its kind that's able to walk on different rough terrains, like pebbles and sand, and climb over obstacles. Other soft robots can only crawl or shuffle on a flat surface, but since this robot can lift its legs, it's actually able to walk, which means that it could potentially be used in search and rescue operations, or to capture sensor readings in environments that are dangerous for humans. Tolley led the research team, which used an Objet350 Connex 3 multi-material 3D printer from Stratasys to print rigid and soft materials together with the same components; this allowed the team to use more complex designs to shape the robot's soft legs.
