How do you achieve a gold robotics badge in The Sims 2 Open for Business?

You can get a gold robotics badge by continuing to work on the robotics station that you bought for your Sim from the Buy Mode. Be patient as it takes lots of time to build these talent badges. It would also help you to build it slightly faster if you have a better skill level in skills that are related to robotics, such as Mechanical and Cleaning.
