Origami

New research by Professor Erik Demaine, lecturer Zachary Abel, robotics engineer Martin Demaine and their colleagues explores whether it is possible to “take any polyhedral (or flat-sided) shape that’s finite (like a cube, rather than a sphere or the endless plane) and fold it flat using creases," writes Rachel Crowell for Quanta Magazine. “By moving finite to infinite ‘conceptual’ slices, they created a procedure that, taken to its mathematical extreme, produced the flattened object they were looking for,” Crowell explains.

Prof. Erik Demaine speaks with Popular Mechanics reporter Sarah Wells about the surprisingly complex math behind wrapping a present. "If [the wrapping] is a square piece of paper, we know the best [way]," Demaine says. "[But] what if I gave you an eight-and-a-half by eleven rectangle? The answer turns out to be really complicated…And again, this is just wrapping a cube. If you're wrapping a general box, it's going to get even messier. Here, we don't even know the right answer."

CSAIL researchers have developed a new robotic gripper that contains an origami skeleton, enabling the device to open and close like a flower and grasp a variety of delicate and heavy objects, reports James Vincent for The Verge “By combining this foldable skeleton with the soft exterior, we get the best of both worlds,” explains Prof. Daniela Rus, director of CSAIL.

TechCrunch reporter Brian Heater writes that researchers at CSAIL and Harvard have developed a soft robotic gripper that can both handle delicate objects and lift items up to 100 times its own weight. “The gripper itself is made of an origami-inspired skeletal structure, covered in either fabric or a deflated balloon,” explains Heater.

In a piece about the growing field of origami, The Economist highlights Prof. Erik Demaine’s work proving that “any straight-sided figure—an octagon, a cityscape silhouette or a blocky Bart Simpson—can be extracted with exactly one straight cut if you fold the paper up the right way first.”

STAT reporter Dominic Smith highlights how MIT researchers are applying the art of origami to developing a new way to deliver cancer medications. Prof. Michael Cima explains that, “the idea here was, is there a way we could do a minimally invasive procedure to deploy some sort of device that will deliver the drug over that entire course of the therapy?”

In this episode of NOVA that explores how origami is being used in scientific innovations, Prof. Erik Demaine speaks about his work applying math to create new origami figures. “It’s mind blowing that the simple operation of folding lets you transform a boring square of paper into super complicated, crazy 3-D shapes," he explains. 

Jennifer Smith of The Boston Globe writes about the fourth annual OrigaMIT convention held November 8, which brought “origami artists from across the country to display their creations and teach attendees to create sculptures from squares of paper.”

Ian Sample of The Guardian reports on how a team of researchers from MIT and Harvard have developed a “Transformer” robot that can self-assemble. "This will rapidly extend the manufacturing capabilities that we have today where configuring an assembly line is done manually and requires a lot of time," Prof. Daniela Rus explains.

Wall Street Journal reporter Elizabeth Yuan writes about the OrigamiUSA convention and Professor Erik Demaine’s talk about his work designing multi-functional origami systems that can be programmed. “You can imagine a piece of furniture that turns into a chair, folds into an umbrella, anything you want,” Demaine explains. 

“When it comes out of the 3D printer, the robot is just a sheet made of a polymer called polyvinyl chloride, or PVC. The sheet is sandwiched between two rigid polyester films. Slits cut into the films affect how the PVC sheet will fold when it is heated,” writes UPI reporter Brooks Hays of new work with self-assembling robots. 

New Scientist writer Aviva Rutkin reports that MIT researchers have developed a new process in which flat cut-outs are able to self-assemble into robots when heated. "What we would like is to provide design tools that allow people who are not experts to create their own machines," explains Prof. Daniela Rus. 

In a piece for Wired, Olivia Solon writes about how Professor Daniela Rus’ research group has developed, “a system of 2D patterns cut into plastic that can self-fold under heat into 3D shapes.” 

Forbes reporter Jasper Hamill describes a new technique developed by Prof. Daniela Rus that allows robots to self-assemble when heated. “The components can be produced simply by heating up the plastic, which is cleverly designed so it folds itself into the right form,” writes Hamill. 

“Eventually she can see a world where people can use an algorithm to analyze an image, create blueprints and print out fully functional robots. This could be a big deal in manufacturing, health care and, yes, toys,” writes NBC News writer Keith Wagstaff of Professor Daniela Rus’ work with self-assembling robots.
