Robots were taught to assemble an IKEA chair
First, the robots had to detect all the parts of the chair. Then they planned their movements to avoid bumping into each other and defined the force with which every movement should be made during assembling.
In Singapore the specialists programmed robots to assemble IKEA chairs. Later they published a scientific paper on the project in Science Robotics.
According to them, “to program robots to assemble a chair, one should consider their ability to perceive surrounding objects, plan their movements, control the interaction with the environment, carry over an object with two “hands” simultaneously”, explained the head of the research Quang-Qiong Pham.
He also pointed out that the researchers decided to study the limits of such abilities of the robots on the example of this task.
For assembling the scientists chose a wood chair Stefan. A couple of robots assembled it in 20 minutes. In the project they used two robot manipulators of industrial manufacturing, parallel grips, force sensors on the “wrists” of the manipulators and a 3D-camera.
Robots first detected all the chair parts and their location, then planned their movements to avoid bumping into each other and defined the force with which every movement should be made during assembling.
