Update: Movie Poster Drawing Robot

We got our robot drawing! We had to mess around with the wiring a bit, but we now have the robot drawing.

The Pen Plotter

We 3D printed the pen holder with 2 holes for the screw mounts. 

As we tested this layout, it was way to flimsy. It kept turning and becoming misaligned.

We then decided to create a backplate to prevent the twisiting and turned due to the ACME screw. This is to make sure the pen is stable enough for drawing.

We took the measurements from the steel plate and laser cut a new one with various holes for adjustment purposes. This set up works ideally for what we want to do.


We also lser cut a board that matched up with the screw holes on the base. This was to make sure that the surface was completely flat for drawing. 4 out of 6 of our holes were off, but that does not affect the positioning of the base plate as it’s held in place pretty firmly.
