Ability to collect the Rubik’s cube is no surprise. The modern neural network takes only a second to solve this puzzle, and for some robots and one second will be much time for this. The company OpenAI, which trained its artificial intelligence to collect the cube with just one robotic hand, decided to face off. According to the developers of OpenAI, the neural network was initially trained to assemble the cube on its own by trial and error. Neural network was not provided with build algorithms and was not given any clues. Instead, a reward system was used in the form of points for success. As soon as the neural network learned to collect the cube in a specially created simulation, the developers connected it to a robotic arm. Interestingly, at first the neural network did not know how to move the metal fingers and how the cube would react to the movements — it had to figure it all out itself. During the experiment, the AI was still able to learn how to assemble the cube completely on its own. According to OpenAI employees, at the moment their system solves the puzzle in about 3 minutes.
Note that the record holder among people in the Assembly of the Rubik’s cube today is a Chinese teenager Yushen Du. He solved the puzzle in just 3.47 seconds.
