Re: [CAD_CAM_EDM_DRO] controlling a servo or stepper by Remote Contorl?

Hi Jeff,

I think the battle bot's are all just R/C models. Bigger motors, with
bigger drivers. R/C is something like PWM, a .5 to 1.5 ms pulse width
drives the R/C actuators. Multiple "frames" of PWM in an R/C signal.
Not easy to get step/dir out out of PWM. The PWM width could be
measured, and converted to a variable pulse. search

HTTP://www.seattlerobotics.org/

for PWM and R/C motor control.
