3D-printed, four-legged robot can walk on sand

  • Scientists have developed the first 3D-printed, four legged robot that can climb over obstacles and walk on different rough surfaces such as sand and pebbles.

  • Researchers led by Michael Tolley, a professor at the University of California San Diego, used a high-end 3D-printer to make soft and rigid materials together within the same components.
  • This made it possible to design more complex shapes for the robot’s legs.
  • Bringing together soft and rigid materials will help create a new generation of fast, agile robots that are more adaptable and can safely work side by side with humans.
  • The legs are made up of three parallel, connected sealed inflatable chambers, or actuators, 3D-printed from a rubberlike material.
  • The chambers are hollow on the inside, so they can be inflated.
  • On the outside, the chambers are bellowed, which allows engineers to better control the legs’ movements.
  • For example, when one chamber is inflated and the other two aren’t, the leg bends. The legs are laid out in the shape of an X and connected to a rigid body.
