A robotic hand with human-like fingers has solved a Rubik's cube in around three minutes. The machine, guided by artificial intelligence, is the first to have managed the feat without being designed specifically for the purpose and to have taught itself. It is built in a way which means it could be used for other things and learnt through a trial-and-error technique known as reinforcement learning. OpenAI taught AI to control the robotic hand which had been developed by the Shadow Robot Company. The AI controlled robotic hand (pictured above) was able to solve the Rubik's cube in three minutes One of the researchers said that the process starts from the very beginning as the AI has to learn how to move the hand.
