last night we installed a full-size wood router on the end of the sudoroom
robot, with a 1/4" diameter endmill, using the metal bracket Elisabeth
made. And we carved a shape into a piece of wood with it.
if you need to route any wood stuff please let me know. I can help you do
it. If you make a simple SVG file with the path you want to carve, the
robot can follow it, similar to the way it drew this dinosaur with a
sharpie:

the coil you're referring to in the video of the robot drawing the
dinosaur was used as a weight to hold the sharpie down in the holder, so
that the sharpie could write on the paper despite the robot not moving
exactly perfectly coplanar with the paper on the floor.
when the robot is in pen-up Z position, the pen is resting at the bottom
of the holder but still not touching the paper. When the robot moves to
pen-down Z height, the pen is resting on the paper with the coil's weight
pressing it down and it's writing. It was a kluge.
also a sharpie is tapered so it doesn't work very well because it's
sloppy in the hole, which is in a 3d printed plastic thing i made just for
holding sharpies. We need markers that are not tapered.
