You Don't Need Expensive CAD To Make Awesome Robots
We've been doing a lot of work with papercraft, and have even picked up a Craft Robo cutter (more on that later). Doing the research we ran across a recent Makezine post featuring a professional looking 5 DOF manipulator arm project created by Anton over at Let's Make Robots.
The robot arm is impressive enough by itself, but we were really intrigued by the fact that he did the whole thing on paper without the assistance of a CAD system, then laid out and cut all the polystyrene frame members by hand.
