Bird Beak Mechanism

Thu, 17 Jul 2014

Back to work on my paper bird 🙂

As I’m sure you remember, I’m aiming to
make the beak move and the wings flap by running separate pushrod, one up each leg. In the original I had used a strip of paper as a pull strap but in this version I’ve used a triangular sectioned rod so that it can be both pulled and pushed. This means that I can drive the beak open rather than having to let gravity do the job.


The beak mechanism works quite nicely, I think the push rod should be clear of where the wing hinges onto the body so there will be no problem with both mechanisms colliding with each other.

Here’s an Instagram animation showing the mechanism in action. Looking good so far!

    It looks so natural, so nice.

      yes whatever happened to this

      yes whatever happened to this project

      everything seemed to be running smoothly with it

      i would like to see it compleated as well unless you encountered some sort of fatal flaw in the design

        I agree with Mr. Cool: this

        I agree with Mr. Cool: this project and many others from Rob Ives, like the office toys (newton craddle, for example) are amazing and really worth doing them. Maybe in this bird project Rob uses a pendulum, I mean, it can be a counterwheight model. It would be really nice the combination of two or more mechanism, for example, the open/close the peak and a sound ones. What do you think, Rob?
