Titan

Titan is a moon of Saturn. By the year 3000, it becomes a great mine of Titanium. A mine being built in Titan collapsed and trapped 1,000 robots workers who will be dead within 300 years. Because of that event, the Titanium price skyrocketed, and since Bender's body is 40% Titanium he sold it. It is unknown if the robots are still trapped or they're already free, though the plan was basically pave over the area and get on with our lives.
