No, it's not a joke.

At its "AI Day" today, Tesla released many details about its progress to develop AI technology to power its self-driving system.

But as we expected, there was a "one more thing" moment, and it was robots.

CEO Elon Musk announced that Tesla plans to build a humanoid robot called Tesla Bot.

Musk described Tesla as already being the biggest robotic company in the world, considering the capabilities of its vehicles to see and understand the world around them and act on that information.

The CEO believes that it makes sense for Tesla to use their significant advancements in computer vision, but instead of deploying in a robot on four wheels, the company will do it in a humanoid robot.

Musk said that Tesla Bot will be geared toward doing "repetitive and boring tasks."
