Title: what about a robotic arm able to write
Post by: @Eric on July 07, 2010, 04:43:59 PM

so basically your pretty much looking at a cnc machine...

unless you can make the arm really strong and not bounce it'll be pretty difficult to make it write clear.

i'd google "CNC" or "DIY CNC Machine" there are heaps of tutorials out there so have a look and see what
you think  ;D

I think that you'd have a better bet with a constant-speed car with a servo off the end with a pen trailing behind the car. You could program different motor sequences for different letters.
