Having done relatively well in a robotics competition that used Lego Technic, I got really annoyed using Legos to build something mechanically complex because of what I dubbed the "Lego Design Flaw." Legos have a 5:4 ratio of width to height (or height to width?) which makes it much more difficult than it should be to build in the full 3 dimensions.
