So, with the new wave of Movie figures and the demand for a good Peterbilt Optimus figure, maybe even one that isn't based on the RofT figures transformation (gasp), and because I like procrastinating, thought I might have a go at designing a movie accurate transformation for a new optimus figure. I decided to do it in the most reasonable way possible, which was naturally with paper and Bionicle parts. I printed out orthogonal pictures of the peterbilt, and a render of Optimus that was scaled to be slightly more than 29ft* tall, compared to the 28ft truck I then made a CCBS skeleton that was the same size as his robot, so I could cut up the truck pieces and stick them onto it. The first part I decided to cut up was the rear wheels, but that kinda turned a bit messy, because of the curves and 3D-ness of it, so I conceded and made a drawing instead: Like the movie the legs are in the cab, but only the lower legs will use parts from the cab in my design. The upper legs are just a shell, which the rear wheels and fenders fold into as shown. Still haven't designed how they attack to the upper legs, because they need to move past the lower legs, in they are folded up like this: Maybe the outer shell of the thigh can fold out to allow the wheels to move into place. The next part I did, which is completely unrelated, is the grill, which I was able to do practically. The other main point of difference for this transformation to make it movie accurate, besides the legs forming from the cab, is to have the grill transform into the chest. After cutting out the grill and attaching it to the chest, as well as the windscreen which is nothing special, I found I could flip the grill around, fold in the sides and use it to form most of the inner chest detail (as in it's molded on the opposite side, not it transforms into it): The last piece I did for this first update is the forearms. Well, a forearm. The main innovation with this is that the top of the hood rotates around to create the top of the forearm. The side of the hood just stays the same, and the rest of the arm is just the forearm model, with the only other bit of transforming being the fist folding into the forearm to leave space for the grill, which isn't made yet. Wow, that's a lot of words, and I'm not sure if any of them make any sense. Hopefully some make sense, and some of the photos are visible. I'll add updates when I develop more of the transformation. *This project brought up a problem with Optimus's scale, which I'm sure I saw someone explain before, but I'll reiterate it. Basically, Optimus being 29ft tall works in terms of logic (28ft truck = 29ft robot), and in terms of scaling with other robots, both in movie and in toys. However, if you scale optimus according to the truck parts on him, like the windscreens, he ends up being way taller (I think that someone said it was 32ft). This not only puts him out of scale with most toys, assuming you keep his truck mode in scale with them, and puts him out of scale in most of the movies, but turing the truck into such a large figure is something I don't think even Peru-kill level black magic can achieve, at least while still having a movie-accurate transformation.
