Although artificial intelligence systems may be able to beat humans at board games, we still have the upper hand when it comes to complicated manual tasks. But now, scientists have created robots that can do something even most humans struggle with: assemble an IKEA chair.

To construct their IKEA masterpiece, the robots first took pictures to identify each part of the chair. An algorithm planned the motions the robots needed to manipulate the objects without causing any collisions; two robotic arms then performed those actions in concert. Feedback from force sensors also helped: When the robot needed to insert a pin into a hole, for example, it would slide the pin over the surface until it felt a change in force.
