Who is the world leader in robotics?

Who, exactly, holds the title of the world leader in robotics? Is it a specific country, or perhaps a prominent corporation? How do we determine who takes the lead in this rapidly evolving field? What criteria do we use to evaluate the advancements and achievements of various nations and companies in robotics? Is it the sheer number of robots produced, or the level of innovation and sophistication in their designs? Are there any particular areas of robotics, such as industrial automation, medical robotics, or consumer robotics, where one particular entity stands out? I'm curious to learn more about the current state of robotics and who is truly leading the way.
