i have old robot built 10 years ago using tinytiger microcontroller, 2 nema23 4-wire stepper motors (1.8 degree), , pair of stepper motor drivers (cyberpak cy-41).
i want rebuild robot challenge local middle school's robotics club, using up-to-date arduino system. puts arduino system in hands of next generation of up-and-coming engineers. i'd rather introduce them modern system (arduino) instead of deprecated system (tinytiger).
this first experience arduino - know little it. professional embedded programmer, work 32-bit arm stuff in eclipse-based ide (i.e. freescale k20 , codewarrior real-time mqx operating system) or 8-bit pic controllers.
what recommendations?
1. arduino platform (i.e. arduino leonardo)?
2. keep existing cy-41 stepper amplifiers?
3. upgrade 2 motor shields maximize compatibility , system integration?
4. there alternative stepper motor driver boards designed arduino have code samples available?
how many shields can stacked? can stack 2 motor shields on single arduino card?
thanks.

don't whatever downgrade motor shields, these high current bipolar stepper motors!
you might want upgrade microstepping drives, these expensive - have
a working system already? use accelstepper library generate step/direction
interface.
arduino platform depends on want - how many i/o? how much
processor power? start uno or similar if unsure, should work out
of box, straightforward.
