Re: [CAD_CAM_EDM_DRO] Re: PWM vs Constant current and G-rex

Hi Simon,

Why wouldn't G-rex work for a hexapod? Now bear in mind that there is a hexapod
CNC machine center, and a hexapod robot. Mobile platform makes me think of a
robot. I was just reading papers on how they run simulations that "learn to
walk" by trying different combinations of leg movements.

In any event, I believe G-rex (G2000, right?) can coordinate moves for 2-6 axis
in CNC. Should make a dandy controller for either a robot or a machine center.

Which were you talking about? I probably missed an early post.

I wonder how hard it would be to write Gcode program to do a tripod stride for a
hexapod robot? I'm not ready to write the simulation software to "learn" the
stride!
