So, I decided to make a transformer, not as complicated as the Michael Bay ones, but more like the vintage toys from the 80's.
The difficult parts are the joints and that everything you make in the robot mode, you have to consider it in the car mode and vice versa.
- 2 arms (car sides)
- 1 main piece: torso, face and thighs (car front)
- 4 wheels
- 4 long pivots (for each limb)
- 4 short pivots (for each wheel)
About the 123D Design software, I have to say: I really like it. It's friendly, you don't need to be industrial designer or engineer to learn it, but having visual-spatial ability helps a lot (relax! most of the makers have it). And it's free! You can download the program in this link.
NOTES: I used the 123D Design 64bits version for PC. My laptop is a Samsung with Intel Core i3-2370M 2.40GHz processor, 4,00 GB RAM and Windows 7.
In the design, I used the orthographic view in almost all of this instructable.
I recommend: when you are working in a project, save it in your computer every time you can, because the program don't have auto-save.
