Is it possible ? Depends on whether you are resourceful or have resources ($$$).
I'm thinking of building something like this; http://axis.unpy.net/index.cgi/etchcnc
The software running these motors is EMC from linux cnc.org. It's intended to be used for metal and woodworking but can be adapted to other uses. I've used this software and had a lot of fun with it.
Those robots in the link you provided are on a whole different level of complexity and cost. Have you asked this question elsewhere ? There must be forums dedicated to robotics.
