Re: A "simple" Hexapod project

Zeroing the hexapod could be a challenge as I'd think that you'd want
to have all the struts at relatively equal tension / compression to
start with. If you used high-lead ballscrews or belts or cables then
powering off the motors and zeroing by hand might be simple and
effective. You'd also need to be able to accurately measure the
relative positions of all the joints and initial strut lengths in
order to model the hexapod in software and probably devise a means
for calibrating.
If I could put together the hardware for a reasonable cost then I'd
probably build a hexapod just for the fun although I'm currently
working on a hybrid design using 3 actuators to tilt the tool
platform in conjunction with 3 linear axes to position it, early
stages but has potential advantages over the 2 rotary axes I'm
currently using on my router.
If you get the hardware together then by all means use my CNC Toolkit
for the software side. It might not be very user friendly but that
could be fixed with some decent documentation and some work on the
user interface.
