Who hasn’t found themselves ready to throw a half-assembled IKEA chair across the room in a fit of frustration? If you are one of the many humans that still struggle to piece it all together, don’t despair: the robots are coming. In a study recently published in Science Robotics, scientists created two robots that are capable of performing the complex movements and possess the planning skills necessary to construct an IKEA chair. The robots are able to assemble a chair in a little over twenty minutes, with 11 minutes and 21 seconds dedicated to planning and 8 minutes and 55 seconds devoted to actual construction.
While computers seem to have surpassed humans in certain cognitive tasks, such as playing chess and Go, until the development of this particular robot, even the most advanced robots struggled to emulate the manual dexterity possessed by humans to complete a complicated task like chair assembly. Additionally, the task requires integration of sight and precise calculation of force necessary to complete a particular step in the process. The team that designed the IKEA assembly robot from Nanyang Technological University in Singapore utilized 3D cameras and force sensors, combined with full-range robotic arms, to equip their machine with the parts necessary to get the job done.

To start, the robots recorded images to properly identify each component of the chair. Next, the robots followed a complex algorithm to plan the movements needed to complete the task without bumping into anything. Finally, the robot arms assembled the parts, guided by sensors to determine the force necessary to secure each component. Although the robots were not fully autonomous, the researchers predict that with ever-advancing artificial intelligence, assembly robots may someday be able to piece together your furniture simply by flipping through the manual.
