Iteration of Initial Design 

...

Iterations between the original design of the casting mechanism include the changing of link 3 to have a slot for the connector rectangle, which connects the casting and positional adjustment mechanisms. When laser cutting the parts, we had iterations for the links due difficulty in assembly because of lengths and diameters of holes.

Output Link

The output link initially had a slider but after testing and analysis, it was concluded that a bearing connection was more effective. 

...

This rectangle was used to achieve 3D motion by connecting the position adjustment mechanism (XY plane) with the casting mechanism (ZY plane) while maintaining the angle of link 3. The casting mechanism link 3 had a rectangular slot at a 45° to be able to attached to the positional adjustment mechanism ground link perpendicularly.
