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.
