Building R2-IQI've been given the green light to build an R2-D2 out of VEX IQ. The current working name is R2-IQ, and my target completion date is 50 days from now, on December 18, 2015.
The plan is to build a full-sized astromech that can be driven by remote control, and has the ability to switch between standing on 2 legs to 3 legs and back to 2 legs. It will be able to drive when on 3 legs. I haven't decided if I want it to drive when on two legs.
The first challenge is creating the shape of the body. I tried out a couple ideas in SnapCAD (VEX cad software) to see where I got the best round shape.
My first try was image #2. The shape and size were very good (the body is just over 18" in diameter) however when I went to build it, I realized the pieces on the skin would not fit, because they were overlapping by about 1/2 inch. (silly drawing mistake)
The second version (#17) was the perfect shape, but not the best size. This version has about a 21" diameter.
Version #3 (image #1) has a less-perfect shape, but a better average diameter. (~18.5") This one will be a little harder to build, because of how some of the pieces will overlap.
I think the slightly larger diameter body will actually take less pieces internally, but I haven't decided, yet, if I want the better shape, or closer diameter.
