Are you talking money here? Robots don't need money. Tokens can be given to people to use the benefits of the robots. People who are fearful that they won't have a place in life, need not be. People will be way more inventive than robots for a long time. People will always be able to find themselves something to do.
The metals, software and chips needed for manufacturing robots needs to be purchased from somewhere. Also, the robots need electricity for their operation, and paid services such as GPS and software subscription to perform normally.
Not if the robots mine and refine the metals, manufacture the software chips, put together and operate the power plants, run the GPS towers and satellites. And why would they need subscriptions to something that they handled the services for?
Robots can be designed to do all this with little to no supervision. And they don't have to be intelligent robots.
Sure, a few people might need to be available for contingencies that were not thought of ahead of time, or for certain kinds of emergencies. But most of this can be handled in the programming. The few people that would be needed, would be around because they wanted to be. Robots would do all the heavy stuff.
So, what would people do? Anything they wanted. Robots would make everything people needed for life and enjoyment. Travel the world. Swim in the Caribbean, or the off Maldives if you like. Transportation is free, handled by the robots. Everything that is made by people is now made by the robots, for free, because it doesn't cost the robots anything to go out and do it. They rebuild their own worn out parts for free.
