RE: [CAD_CAM_EDM_DRO] Re: Open (i think) design for a parallel robot (reprap may be interested)

Someone in this thread suggested that a hexapod would be difficult
for homebrew construction. I built my hexapod (two now) because it
was easier to homebrew.

Why is it easier?

For me, it was easier because:

1) no large cast parts are required
2) no precision flat surfaces. No scraping required.
3) there is much similarity between parts. You need six legs -- all the same.
4) it is not necessary to home-manufacture any precision parts that
move against each other. No matter if you use threaded rod or ball
screws, the only parts that slide against each other are the screws
and matching nuts.
5) the emphasis is on the control system (software and electronics),
rather then the mechanical implementation. I have better tools for
compiling code and making PC boards than I do for making metal parts
(which is part of why I want a machine in the first place).
