New gym opens to train robots

Elon Musk has opened a gym for robots, called OpenAI Gym. Mr Musk founded the companies Tesla Motors and PayPal. OpenAI Gym is free for code writers to test their work on robots and share their algorithms. These are special computer programs that can solve problems and deal with lots of information.

Mr Musk explained why OpenAI Gym is free. He said: "Our goal is to advance digital intelligence in the way that is most likely to benefit humanity as a whole." It is like when a dog gets a treat for learning something new. If an algorithm does well in the gym, it gets a reward. If it fails, it doesn't. Musk wants algorithms to multi-task.
