Harvard and MIT engineers, showing a reckless disregard for the robocalypse, have created origami robots that can self-assemble themselves — from a flat piece of paper and polystyrene – and walk away in just four minutes.
“Getting a robot to assemble itself autonomously and actually perform a function has been a milestone we’ve been chasing for many years,” says Harvard’s Robert Wood, barely stifling a maniacal cackle, Extremetech reported.
The origami robots are made from composite sheets of paper and polystyrene (Shrinky Dinks). The engineers print some conductive channels onto these sheets, and then use a laser machining system to create the necessary origami fold pattern. Each hinge contains an embedded circuit that, when instructed by a microcontroller, produces heat, which causes the hinge to fold. Then, by adding a couple of motors, and a microcontroller that knows the necessary fold pattern, the robot comes to life — first by folding into its predestined shape, and then by walking away.
