What method does the robot use to learn new things?

OpenAI,an artificial intelligence research organization in the United States,has recorded an industry milestone in its quest to build general purpose,self-learning robots.The group’s robotics division said that Dactyl,its humanoid robotic hand developed last year,has learned to single-handedly solve a Rubik’ s Cube puzzle.OpenAI sees the feat as a leap forward both for the dexterity of robotic appendages and its own AI software,which allows Dactyl to learn new tasks using virtual simulations before it is presented with a real,physical challenge to overcome.
