How much will an AI robot cost?

I'm curious, how much would one typically expect to pay for an AI robot? Are there varying price points depending on the robot's capabilities or is there a standard cost range? Is it a significant investment, or is it something that's accessible to a wider audience? Additionally, are there any hidden costs or maintenance fees that one should be aware of before making a purchase? I'd appreciate your insights on the overall cost structure of acquiring an AI robot.
