I saw the FebRovery event on flickr and enjoyed looking at all the unique rover creations. Classic space was one of my favorite themes as a kid, so I thought I'd build a little Lego rover and join in. It only took me about an hour or so, which wasn't enough for me. That's when I built this mobile space crane. It's somewhat functional, with manual controls. The crane rotates 360 degrees and goes up and down.
