OpenAI's AI-based robot learns to solve Rubik's cube with one hand

San Francisco-based AI startup OpenAI's humanoid robotic hand Dactyl has learned to solve a Rubik's cube one-handed. "Plenty of robots can solve Rubik's cubes very fast. The important difference between what they did there and what we're doing here is that those robots are very purpose-built," OpenAI robotics lead said. Dactyl robotic hand was first developed last year.
