We have seen that is very hard to calculate a relational position of each joint in the trigonometric functions.

 

In order to intuitively design a linkage mechanism, I have already completed some new techniques. It is possible to flexible and quick 3D design. From this reason, no need exceptional program.

 

There is some standard technologies which equipped by 3DCG animation application softwares (like Blender or 3dsMax).

 

- Bones and Skeletons

- Inverse Kinematics

- Constraints

 

Using the techniques described above, We easily simulation of linkage mechanism can be. This is a idea of reversing the normal usage.

 

In this way, by the theorem that I have completed, it will be straightforward to design a complete kinetic mechanism. adding the fluctuation, incomplete movements also be able to design. (such as drunken staggering gait)

 

So, as a more intuitive approach, advantage of IK, there is a function given the value of stretch to the joint. this elongation margin lead us to a lot of opportunity for discovery.
