A Robot Built An Ikea Chair In 20 Minutes & It’s Actually A Big Scientific Leap Forward

Look, robots and artificial intelligence (AI) get a bad rap, from all the fuss around them taking over our jobs, to rising up and overthrowing humans. But some folks may rethink their positions after finding out that ~science~ has gifted us with robots that can put together Ikea furniture.

A report published April 18 in Science Robotics chronicles researchers’ successful attempts to build a robot (using “entirely off-the-shelf parts,” by the way — “two industrial robot arms with force sensors and a 3-D camera,” according to Wired) that can take care of one of the actual most annoying things on the planet: The need to put together your new flatpack yourself.

Researchers reported that the robot arms put together a Stefan chair from Ikea in 20 minutes. Just 20 minutes. Imagine a future where you bring your flatpack home and spend 20 minutes having Netflix beamed directly into your eyeballs, and then simply turn around and see that your furniture is completed. No muss, no fuss, no misery naps or resorting to paying some guy on Craigslist to come build the thing for you.

According to Wired, this is a big deal not just because it could chuck approximately 80 percent of the daily human struggle out the window, but because robots usually “struggle mightily to manipulate objects in a world built for human hands.” So the fact that researchers managed to put together a robot that can follow Ikea’s instructions and manipulate the various screws and pegs signifies a real push forward in robot dexterity.

If you’re wondering how the robot arms were able to follow instructions when everyone knows that is notoriously impossible, well, the researchers helped them get started. According to Wired, researchers created a code version of the typical quote-unquote super-simple illustrated assembly instructions. “Then they place[d] the pieces in a random pattern [in] front of the robots, which eyeball the wood with the 3-D camera.” It was the robot’s job to take the list of instructions the researchers gave them and match them to the randomized parts.

Here’s how that process works: “What the robot does is to first figure out where exactly is the original position of the frame,” Quang-Cuong Pham, an engineer out of Nanyang Technological University in Singapore, told Wired. Once the robot figures out the original position, it “calculates the motion of the two arms automatically to go and grasp it and transport it.”

This robot, created by researchers in Singapore, took 20 minutes 19 seconds to make and execute a plan to assemble an Ikea chair.

Researchers in Singapore explained how they created a robot that could devise and execute a plan to put together an Ikea chair.

Wired explained that the two arms have to coordinate motions, and because the camera “only has an accuracy of a few millimeters,” the robots will have to make up for that shortfall sometimes by feeling around for where to insert pegs or slide pieces together. For example, if the robot is trying to insert a peg, it will make “swirling motions around the hole, and when it feels the force pattern change, it knows the peg has dropped in slightly, then will apply more force to fully insert the thing.”
