As I use the 123D Design software more, I am starting to understand the quirks of the software but I have also found an excellent series of youtube videos from a public library that explain how the current version of the software works.
I have also learnt an important word in animatronics- Swash Plate. The swash plate is the connector between the control cables and the part being moved. So in the animatronic eyes, the swash plate will snap into the interior of the eyeball and because the control cables are tied to the four holes, the plate will pull the eyeball around according to the cables that are being pulled by the servos. I do really like how this design is drawn with all the part sketches in orientation to each other. It means I can see where there are parts that might get in the way of other parts when the whole project is assembled.
I am looking forward to designing the E-Bar bracket next. In the meantime, I am trying to negotiate the loan of a 3D printer from the Industrial Arts Faculty at my school so I can print my mechanism!
