Puzzle-solving robotic hand marks AI milestone

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.
