The secret is simple... prototyping & continuous improvement.

On the most successful robots each mechanism is prototyped, thoroughly tested, and improved before it goes into the final design. Try it.

After you figure out WHAT your robot is going to do, and you come up with some ideas on HOW the robot is going to do it, you need to prototype your ideas.
John,

From the pictures you post, it seems like 148 moves directly from cardboard and Vex into sheet metal and the production robot. Is this the case? For the robots I've worked on, we typically went from cardboard to plywood to plywood & shafts powered by drills to rough cut aluminum then to the final robot part. It seems like you skip by that rough aluminum step. I know you use a lot more CAD than we did, but do you just trust that your Vex and cardboard dimensions are "good enough"? Or do you end up rebuilding some manipulators if you find that your dimensions don't work as well as you anticipated?
