The process is well, but the internal structure has a lot of problems, the organ of knife is using concept of whitworth quick return mechanism. Except this, also have to make sure the knife is move smoothly when control by servo motor, for the first maker it has using 3 layer of figure to stable the motor servo with knife and mouth, also the knife with auxiliary, and the shadow of figure must see it clearly when show in the screen.

The Problems:

-The knife is too longer to show out on the figure, so it have mo make it short and make sure other organ working normally.

-The shadow of 3 layer by figure is not very clearly to see, because their have 3 layer the on the shadow it also show 3 layer on the screen, it look like hazy.

-the figure is using cardboard box to made it so the durability is not longer.

The Arduino Nano part:

-So far the coding has no much problems, testing of sound sensor, servo motor, and DC motor.
