Equipment Upgrades

The latest edition of Frontiersman (14) has some good stuff in it regarding upgrades. Though at first glance it appears to be more for cybernetics rather than traditional robots. What I would like to see in this thread is a compilation of possible upgrades, with suggestions on costs and a discussion on a way to limit the number of upgrades and estimate energy usage. We just need to keep some parameters for balance. I'd hate to see a two foot tall robot looking like a Swiss Army knife with "one of everything".
