While this modification isn't extremely hard to handle on your own, out the the box support for motor feedback might make autonomous mode alot easier and more reliable for lots of teams. |
Okay, I just saw a robot application of this using Lego system motors yesterday. Charmed labs has created a new interface (Gameboy based) for Botball that uses back emf and reportedly has precision down to 10,000 cpr.
Is back emf possible using the victor speed controllers? Using the FRC 2005 system, would we need to add in a voltage sensing circuit between the motor and victor?
Mostly curious as we will attempt to add non-driven encoder wheels to help with autonomous this year.
Okay, I just found a lot more on this topic in this thread
