Rob has been putting together a great little series of LEGO robots, each with a different designation and function. The building techniques are good, with some smart connections and solid color choices, but it’s the presentation of the models which really sets these creations apart — detailed technical spec sheets accompany shots of the bots in action.

The Hazardous Environment Suit gets a technical breakdown plus a “hero shot” of it exploring a newly-discovered planet…

And if you need some robotic assistance closer to home, every space station hangar bay should have access to one of the Utility models…

This bad boy has clearly got a fairly hefty lift capacity…

I’d heartily recommend a visit to the builder’s photostream to check out more images of robot companions at work.
