Bird Automaton

This mechanical bird automaton is completely 3D printed and requires no assembly. Rotation of the crank is transformed into vertical motion by a scotch yoke mechanism which in turn makes the body of the bird go up and down. At the same time, links are connected to each of the wings, resulting in a lifelike movement.

​Hyperbola Automaton

This model illustrates a property of hyperbola and twisted cylinders. A tilted rod revolved around an axis will create the contour of a hyperbola. It is completely 3d printed in one part and requires no assembly.

Hinged Dissections

Introduction
A hinged dissection is a sort of geometric dissection where the individual parts are hinged together amd rearrangement of the parts can change the appearance of the object. 
​
​Design Algorithm
The following hinged dissections are generated by simplifying two target shapes into pixelated enitities and figuring out a way to transform between them. The design process can be described by the  following steps:

1. Pixelate two or more target shapes.
2. Make sure the shapes are of the same area.
3. Overlay the target shapes and select the largest common area as a fixed piece.
4. Divide extremities into right angled equilateral triangles. This prevents self-locking.
5. Hinge the pieces so that they reach the target shapes. Simplify if possible.
