Week 7 – Wood Cutting and Math

After finishing my garment, I should move on to the highlight of the project, the wings. So back to the drawing board where I have to look at the details and get exact measurements for the wings.

Here is the plan for the wings:

23945459-5af8-4aad-a07c-0f25fd2b91d8

The wings are made up on 3 major joints and has at least 3 servo each.

Servo 1: Rotating the from sideways to back

Servo 2:  rotating the wings upwards to down wards

Servo 3:  extending the wings.

Servo 1 and servo 2 is pretty tricky to attach as I need to make a mechanism to make it be able to be a semi-hinge ( so it can be moved on 2 axis). I asked around if there are similar mechanism around the school but the other equipments are far too bulky and heavy to be added on. I might be making it myself.

Servo 3 is the central servo that can manipulate many different gears (which controls the bones of the wings). Having different sized gears is able to make the each bone of the wing extend in the correct angel.

Thanks to Li Xuan again, I was apple to learn how to some basic wood cutting/drilling techniques so that I can make the basic frame of the wings.
