The first origami robots arrive

The first origami robots arrive

Researchers at Harvard University and MIT have developed a technique inspired by origami folding which is able to move from a platform in an articulated structure and move independently robot. A compound of the copper layers, paper and shape memory polymer, this robot can be manufactured inexpensively with a laser cutter.

Transformers, these robots capable of changing well-known to children and fans of sci-fi form, now have everything there was more real competitor. A team including researchers at the Wyss Institute at Harvard University and the Massachusetts Institute of Technology has unveiled a prototype robot that changes shape to move from a flat structure to a quadruped able to move, all without any external intervention.

The transformation takes four minutes and then the robot can move at a speed of about two inches per second. The scientific paper published in the journal Science explains that the design principle of this self assembly robot based on the Japanese art of origami folding. A traditional method has already been used to manufacture a lithium ion battery foldable and deformable. The robot is designed from a composite heat-sensitive surface of which is carved with cuts and grooves to create hinges. The resistors will be heated so that the deformable regions bend and cool and form the three-dimensional structure. Small engine then allow the robot to move.
