Woodpecker automatization process

As well as developing the mechanical components, the automatization of the Woodpecker was a debugging process until the optimal performance was achieved.  

Woodpecker First Prototype

After both manufacturing and automatization process, the first Woodpecker fully operational prototype was created.

The Woodpecker is the perfect combination of art and engineering which provides the possibility to anyone to explore their artistic side.

The Woodpecker acquired its name because of the way it stamps. The solenoid performs a series of quick hits every time a stamp is needed, this was done in order to assure that the stamp gets all the color possible 

Product Comments

It should be mentioned that even though for this first prototype the Woodpecker is constrained by a small area of action with just 4 choices of colors, The Woodpecker can easily increase its work area and add more color choices without compromising the basic design 

One of the main challenges during the manufacturing process was figuring out a way to fix the end effector to the stepper motor so it can withstand constant hits from the solenoid every time a stamp was performed. This was achieved by setting a set screw between the end effector color wheel cap and the stepper motor.

Comments

One component that needs to be improved in the Woodpecker are the stamps more specifically how they are manufactured. Because their surfaces were not completely flat which does not allow the stamp to completely hit the paper surfaces and deliver all the color possible.
