I’m imagining the robotic arm picking up the grease and applying it to its hinges. What, that is exactly what you are planning to do, isn’t it? Will it replace its worn body parts too, before expiration? It is the obvious next step, isn’t it? You are right, this is a billion dollars market.

TBH, I recently finished the code for a product that did almost exactly what you are describing, but for a very specific domain and use case, so yeah, there's a market.
