Ok you may now be thinking 'OMG - this project is way too complicated and expensive for me' ..... Well, if that is the case, I'd have to say you're probably wrong. For a start, there currently is no automation so it really is just a robotic aid, like a prosthetic arm that will do things on a microscopic scale.
This is a manually operated machine - an array of sliders, knobs and buttons are used to pick up, move the components and place them - so its all done through finger action by looking at a small video screen for the microscopic facility.
The actual CNC parts come from an engraver kit which itself is relatively cheap and easy to assemble. The PCB is easy to assemble and, of course, has no SMT parts. Seriously, if your hands aren't steady enough to work with SMT components or you just don't want to mess up a complicated board fabrication then this machine might be the solution.
