last night Leif and I installed a roto-zip rotary cutting tool on the end
of the robot arm.
it looks just like this one:

we don't have any tool bits for it though. It needs a sideways-cutting
bit with a 1/8" diameter shaft. they make them for wood. it would be
possible to cut metals too if you're careful, but a bit for that purpose
would be called an "endmill"
please let me know if you want to use the robot with its wood-cutting
tool. if you want to cut out a shape, for example, you will need an SVG
file for starters.
thank you
