Hi everyone,

I am looking to make a small machine that can draw using a marker pen.

A3 kind of size
I would like it to be fast
light weight
Wall mounted
Small Z movement - only needs to lift the pen from the drawing surface
Control - I would like control the machine using something like an arduino - just drawing predefined images.
The machine will be on display so the final look is important.
The drawing "head" of the machine needs to be able to move out of the way so the view of the finished drawing is not obstructed.

Any advice/ideas/links where to start? I was thinking something like a Delta Robot (is this the right term?) type of thing would be good - fits the looking interesting requirement! - looks very complicated mind....

Any input appreciated! :)

Jim
